+[Keep a Changelog](https://keepachangelog.com/en/1.1.0/). Release notes on
+GitHub are taken from the matching section here.
+
+## [Unreleased]
+
+## [0.3.0] - 2026-09-18
+
+### Added
+
+- Custom Discord presence. `integrations.discord_rpc.text.title` replaces the
+  name in "Playing Nightcap", and `integrations.discord_rpc.images` sets the
+  large and small icons and their hover text. Text and image fields accept
+  `{place_name}`, `{place_icon}`, and `{creator_name}`. A field that expands
+  an empty placeholder is left out, and `text.state: ""` hides the state line.
+- The default Discord card now matches Sober: the title is "Roblox", the
+  details line is "Playing <experience>", the state is "by <creator>", and
+  the Roblox badge sits inside the experience icon. The creator comes from the
+  same Roblox games request that already fetches the experience name. With
+  `show_place_name: false` the creator is hidden too, so the card shows only
+  the title and timer.
+- `--profile <file>` writes a Chrome-format trace of the Vulkan adapter's
+  work: presents, GPU waits, submits, ETC2 texture decode, and pipeline and
+  shader creation. Open it in ui.perfetto.dev. `docs/BENCHMARKING.md`
+  describes the benchmark runs, and `scripts/summarize_profile_trace.py`
+  turns traces into a before and after table.
+
+### Fixed
+
+- Texture uploads stalled the frame they were submitted on. ETC2 batches
+  decoded on worker threads but were then resampled one upload at a time on
+  the submitting thread, which at the default 4x upscale is sixteen times the
+  decoded texels. Resampling now runs on the same worker pool, in two passes so
+  mip level 0 still resolves before the mips built from it. In a 70k-part
+  place the worst `vkQueueSubmit` fell from 167ms to 92ms.
+- Most ETC2 batches decoded on a single thread. Workers were created and
+  joined per batch, so the parallel floor had to cover that cost and sat at a
+  1024x1024 image; batches under it ran on the caller, which was 54% of all
+  decode time in a 70k-part place. Decode workers are now a persistent pool,
+  and the floor drops to a 128x128 image. Mean decode time in that place fell
+  from 8.2ms to 4.7ms, and 11.8ms before both texture fixes.
+- On CPUs with a wide core-speed spread, Feral GameMode pinned the process to
+  the few fastest cores, concentrating Roblox's worker pool onto them instead
+  of spreading it. With `performance.gamemode: auto`, a request that narrows
+  the CPU affinity is now released again, which releases the pin. Set
+  `pin_cores=no` in `~/.config/gamemode.ini` to keep GameMode without the
+  pinning, or `performance.gamemode: on` to accept it. See
+  `docs/PERFORMANCE.md`.
+- With `show_place_name: false`, Discord no longer shows the experience
+  thumbnail or its name on hover.
+- The host main thread no longer spins on the engine's message pump, which
+  cost about half a core and 146,000 empty calls a second. It now rests 100 µs
+  between polls: sleeping when the governor is `performance`, parking the
+  core with TPAUSE on CPUs that have it, spinning otherwise. With GameMode
+  setting the governor, process CPU in a 60k-part place fell from 216% to
+  107% at the same 120 fps. `MOCKTAIL_ENGINE_PUMP_REST` forces a mode; see
+  `docs/PERFORMANCE.md`.
+- ETC2 uploads with a `bufferRowLength` or `bufferImageHeight` larger than
+  the image read the padded rows as packed data and decoded garbage.
+- ETC2 resampling created and joined worker threads on every batch. It now
+  runs on the persistent decode pool.
+- A failed trace write left the profile writer thread waking every 250 ms
+  for the rest of the session. It now exits.
+- The `--profile` trace gains a `pump` slice for the engine's main-thread
+  step.
+
+## [0.2.0] - 2026-09-16
+
+### Added
+
+- FAQ covering Discord RPC, log locations, and VR, adapted from upstream.
+- `input.raw_mouse` in `config.yaml` sends mouse look deltas in the host's
+  own units. Turn it on when first-person aiming feels too slow or too fast
+  under fractional display scaling. Off by default.
+- Nightly AppImage builds, published as the `continuous` prerelease. They are
+  untested; use a tagged release for normal play.
+
+### Changed
+
+- Values in `fflags.json` now win over the performance preset instead of
+  stopping the launch. Startup prints each key it kept.
+- Discord Rich Presence uses Nightcap's own Discord application, so it shows
+  as "Playing Nightcap". Terms and privacy pages for it live on the
+  project site.
+- Discord Rich Presence is on by default. Set
+  `integrations.discord_rpc.enabled: false` to turn it off.
+- The AppImage build verifies its reduced dependency packages against digests
+  taken at build time, rather than a digest list kept in the repository.
+
+### Fixed
+
+- Mouse look keeps responding after a long turn. The tracked pointer position
+  could drift past the edge of the view, which swallowed every reversal until
+  the mouse travelled all the way back.
+- Nightcap no longer refuses to start with `cannot lock appStorage`. It
+  created its own credential directory using the process umask, then rejected
+  that directory for being group writable. Systems with a permissive umask,
+  such as `002`, failed on first run.
+
+## [0.1.0] - 2026-09-15
+
+First Nightcap release, forked from komaruworld/mocktail.
+
+### Added
+
+- ETC2 and EAC texture emulation on Vulkan, so games that use compressed
+  mobile textures render correctly on desktop GPUs. Decoding runs on worker
+  threads to avoid stutter.
+- PNG texture overrides in `~/.config/mocktail/textures`, keyed by upload
+  hash, with a dump mode to find the texture you want to replace.
+- Small textures are upscaled 4x by default. Set
+  `MOCKTAIL_SMALL_TEXTURE_UPSCALE=1` to turn it off.
+- AppImage and signed Flatpak builds on every release tag. The Flatpak repo
+  is published at https://coderdayton.github.io/nightcap/.
+- Roadmap in `docs/ROADMAP.md`.
+
+### Changed
+
+- Frames are presented as soon as they are ready instead of waiting in a
+  queue, which lowers input latency.
+- Roblox now sees the real host RAM and display size instead of a low-end
+  phone profile.
+- App ID is `io.github.CoderDayton.nightcap`, so Nightcap installs next to
+  upstream Mocktail. The binary and config paths keep the `mocktail` name.
+- New name, icon, and colors.
+- The desktop entry launches on Wayland and points at the installed binary.
+
+### Fixed
+
+- Servers no longer kick with error 319 shortly after joining.
+- The FMOD output-device bridge is optional, so the updater no longer fails
+  without it.
+- The AppImage build no longer fails on stale checksums for the slimmed
+  Arch packages.

+# FAQ

-[How do I change my FPS?](/FAQ.md#how-do-i-change-my-fps)
+## How do I turn Discord RPC off?

-### How do I change my FPS?
+RPC is on by default. It never signs in to Discord and never reads an
+account token. To turn it off, launch Nightcap once to create the config,
+then close it. Open `config.yaml`:

+- Native / AppImage: `~/.config/mocktail/config.yaml`
+- Flatpak: `~/.var/app/io.github.CoderDayton.nightcap/config/mocktail/config.yaml`

-Go to $HOME/.config/mocktail, there is a file called config.yaml (appears after opening for the first time mocktail)
+For native installs, a custom `$XDG_CONFIG_HOME` replaces `~/.config`.

+Set `enabled` to `false` under `integrations.discord_rpc`. If the block is
+missing, add it under the existing `integrations` section:

-<img width="460" height="241" alt="image" src="https://github.com/user-attachments/assets/b30b1fea-4937-4858-937a-3096a9e8b2ad" />
+```yaml
+integrations:
+  discord_rpc:
+    enabled: false
+```

+Save the file and restart Nightcap. Set `enabled` back to `true` to turn
+RPC on again.

-with your text editor of preference search for "graphics" 
+## Can Discord count Nightcap as Roblox play time or quests?

+No. Discord only credits play time and quests to games its own scanner
+detects, and Rich Presence never counts. On Linux the scanner only matches
+games with a Linux entry in Discord's list. Roblox has none, so no process
+name Nightcap could use would be detected. Only Roblox or Discord can change
+that.

-<img width="1022" height="619" alt="image" src="https://github.com/user-attachments/assets/f86791e9-7ac3-4d13-b81b-3cf9e3e64c3d" />
+## Where can I find logs for a bug report?

+Nightcap saves logs automatically. Reproduce the issue, close Nightcap, and
+attach `latest.log`:

-change the display value to your desired fps, also turn off vsync if you want more fps than your display supports
+- Native / AppImage: `~/.local/state/mocktail/logs/latest.log`
+- Flatpak: `~/.var/app/io.github.CoderDayton.nightcap/.local/state/mocktail/logs/latest.log`
+
+For native installs, a custom `$XDG_STATE_HOME` replaces `~/.local/state`.
+
+## Can I play in VR?
+
+VR is experimental and lives on upstream's `vr` branch, which does not
+include the Nightcap changes. Install the
+[build dependencies](README.md#building), then switch to that branch and
+build:
+
+```bash
+git remote add upstream https://github.com/komaruworld/mocktail.git
+git fetch upstream
+git switch -c vr upstream/vr
+git submodule update --init --recursive
+cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DMOCKTAIL_ENABLE_VR=ON
+cmake --build build -j4
+```
+
+Start WiVRn or SteamVR/ALVR, connect your headset, then run:
+

+## About this fork
+
+Nightcap is a fork of [komaruworld/mocktail](https://github.com/komaruworld/mocktail)
+with extra fixes for playing on a PC. The program and config paths keep the
+`mocktail` name so upstream fixes still apply cleanly. The app ID is
+`io.github.CoderDayton.nightcap`, so Nightcap and upstream can be installed
+side by side.
+
+- **Lower input lag.** Frames are shown as soon as they are ready instead of
+  waiting in a queue.
+- **Sharper textures.** Small textures are upscaled 4x by default, and you
+  can replace any texture with your own PNG in `~/.config/mocktail/textures`.
+  A ready-made crosshair is in [`textures/`](textures/README.md). Set
+  `MOCKTAIL_SMALL_TEXTURE_UPSCALE=1` to turn the upscale off.
+- **ETC2 textures on any GPU.** Games that use compressed mobile textures now
+  render correctly on desktop GPUs, without stutter.
+- **No more error 319 kicks.** Servers no longer drop you shortly after
+  joining.
+- **Correct device info.** Roblox sees your real RAM and screen size.
+- **Better desktop launcher.** Runs on Wayland and always finds the installed
+  binary.
+
+Everything else works the same as upstream. See the
+[roadmap](docs/ROADMAP.md) for what is coming next, the
+[changelog](CHANGELOG.md) for what each release changed,
+[performance](docs/PERFORMANCE.md) for CPU load, heat and the knobs that change
+them, and the [FAQ](FAQ.md) for Discord RPC, logs, and VR.

+## Install with Flatpak
+
+```bash
+flatpak install --user https://coderdayton.github.io/nightcap/nightcap.flatpakref
+flatpak run io.github.CoderDayton.nightcap
+```
+
+Updates arrive through `flatpak update`. Nightcap is not on Flathub yet.
+
+## AppImage
+
+Grab the AppImage from the
+[latest release](https://github.com/CoderDayton/nightcap/releases/latest),
+make it executable, and run it:
+
+```bash
+chmod +x Nightcap-x86_64.AppImage
+./Nightcap-x86_64.AppImage
+```
+
+Or build and install it from source using the steps under
+[Building](#building). There are no AUR, DEB, or RPM packages of Nightcap.
+Upstream ships those for unmodified Mocktail, see
+[komaruworld/mocktail](https://github.com/komaruworld/mocktail#readme).

+# Benchmarking
+
+A pull request that claims a speedup shows before and after numbers taken
+the way this guide describes. Numbers from different machines are not
+compared with each other. Each run is compared with a run on the same
+machine.
+
+## Two layers, two tools
+
+Roblox measures its own work. Nightcap measures the layer between Roblox and
+your driver.
+
+| Layer | What it covers | Tool |
+| --- | --- | --- |
+| Roblox | Scripts, physics, rendering jobs, network | Roblox's stats overlays, Shift+F4 and Shift+F5 in game |
+| Nightcap | Vulkan adapter: present, swapchain and GPU waits, submits, ETC2 texture decode, pipeline and shader creation | `--profile` |
+
+A Nightcap change should move the `--profile` numbers. If it only moves the
+Roblox overlay numbers, say so in the pull request, since the cause is then
+less direct.
+
+## Recording a trace
+
+```sh
+mocktail --profile ~/nightcap-before.json
+```
+
+The Vulkan adapter writes a Chrome-format trace to that file, a few times a
+second. The file is valid JSON after every write, so a session that crashes
+or is killed still leaves a readable trace. Exit from the Roblox menu when you are done. Open the file
+in [ui.perfetto.dev](https://ui.perfetto.dev) or `chrome://tracing`.
+
+Expect about 130 bytes per event, around 15 MB per minute at 240 FPS.
+Profiling is off unless `--profile` is given, and `MOCKTAIL_PROFILE_TRACE`
+does the same thing as the flag.
+
+### What the trace contains
+
+Each slice is named after the call it times, on the thread that made it.
+
+| Category | Slices | Arguments |
+| --- | --- | --- |
+| `present` | `vkQueuePresentKHR`: the whole adapter present, including the text overlay | `result` |
+| `present` | `host present`: the host driver's present, nested inside the slice above | |
+| `wait` | `vkAcquireNextImageKHR`, `vkAcquireNextImage2KHR`, `vkWaitForFences`, `vkWaitSemaphores`, `vkWaitSemaphoresKHR`, `vkQueueWaitIdle`, `vkDeviceWaitIdle` | |
+| `submit` | `vkQueueSubmit`, `vkQueueSubmit2`, `vkQueueSubmit2KHR` | `submits` |
+| `texture` | `etc2 decode`: CPU decode of ETC2 textures before a submit | `uploads`, `compressed_bytes`, `decoded_bytes` |
+| `pipeline` | `vkCreateGraphicsPipelines`, `vkCreateComputePipelines` | `count`, `cache` (1 when a pipeline cache was passed), `result` |
+| `pipeline` | `vkCreateShaderModule` | `bytes`, `result` |
+| `pipeline` | `vkCreatePipelineCache` | `initial_bytes`, `result` |
+| `pump` | `nativeCallMessagesFromMainThread`: the engine's main-thread step, on the host main thread. Only calls of 20 µs or more are recorded; the empty polls between them are not. | |
+
+The `frame interval (ms)` counter is the time between successive adapter
+presents. `vkQueuePresentKHR` time minus `host present` time is the adapter's
+own cost per frame.
+
+## The benchmark runs
+
+Run every scenario before and after the change, on the same build type
+(`make build`), with the same `config.yaml`. Close other GPU-heavy apps.
+Record `graphics.frame_rate_limit` and `graphics.vsync` in the pull request,
+because a frame cap hides frame time gains.
+
+| Scenario | How to start | What to do | What it shows |
+| --- | --- | --- | --- |
+| Home screen, cold | `mocktail --profile home-cold.json` with an empty shader cache (below) | Wait 30 s on the home screen, exit | First-load stutter: `pipeline` and `texture` slices |
+| Tower of Hell | `mocktail --profile toh.json --launch-uri "roblox://experiences/start?placeId=1962086868"` | Stand still at spawn for 60 s, exit | Steady-state frame time on a light scene |
+| Murder Mystery 2 | `mocktail --profile mm2.json --launch-uri "roblox://experiences/start?placeId=142823291"` | Stay in the lobby for 60 s, exit | Frame time with many players and a busier scene |
+
+For the cold run, point the driver's shader cache at an empty directory, so
+your normal cache is left alone:
+
+```sh
+cache=$(mktemp -d)
+MESA_SHADER_CACHE_DIR="$cache" __GL_SHADER_DISK_CACHE_PATH="$cache" \
+  mocktail --profile home-cold.json
+```
+
+`MESA_SHADER_CACHE_DIR` applies to Mesa drivers (AMD, Intel) and
+`__GL_SHADER_DISK_CACHE_PATH` to the NVIDIA driver.
+
+Run each scenario three times and keep the median run, since one run can
+catch a background stall.
+
+## Comparing runs
+
+```sh
+scripts/summarize_profile_trace.py toh-before.json toh-after.json
+```
+
+This prints a Markdown table with one column per trace: frame count, frame
+interval mean, p50, p95, p99 and max, then count, total, mean, p99 and max
+for every slice name, largest total first. Paste the table into the pull
+request and attach both traces.
+
+For frame time, compare p95 and p99 as well as the mean. Stutter shows up in
+the tail first. For first-load work, compare the `total (ms)` rows of the
+`pipeline` and `texture` slices from the cold run.

+# Performance and CPU load
+
+What Nightcap does to your CPU and GPU, which knobs change it, and how to
+measure rather than guess.
+
+## GameMode core pinning
+
+Nightcap asks Feral GameMode for a performance session at startup
+(`performance.gamemode`, default `auto`). GameMode raises the CPU governor and
+the process priority, which helps.
+
+On a CPU with a wide spread of per-core maximum frequencies — Intel P-core and
+E-core parts, AMD parts with preferred cores — GameMode also pins the process
+to the fastest cores. On a 32-thread host that can mean 4 usable threads out of
+32. Roblox spreads its work across a worker pool, so the pin concentrates that
+pool onto a couple of physical cores instead of spreading it. Those cores sit
+near their boost ceiling and run hot while the rest of the chip idles.
+
+GameMode re-applies the pin roughly every 5 seconds, so widening the mask from
+inside the process does not hold. Releasing the request does release the pin.
+
+Under `auto`, Nightcap therefore checks its CPU affinity immediately after the
+request. If GameMode narrowed it, Nightcap ends the request and prints:
+
+```
+  [gamemode] released: it pinned this process to a subset of the CPUs, ...
+```
+
+The trade is that GameMode's governor and priority boost go with it. To keep
+those and lose only the pinning, turn pinning off for every game on the host:
+
+```ini
+# ~/.config/gamemode.ini
+[cpu]
+pin_cores=no
+park_cores=no
+```
+
+GameMode reads `$XDG_CONFIG_HOME`, `/usr/share/gamemode` and `/etc`, in that
+order. It does not read anything under Nightcap's own config directory, so this
+file has to live in one of those three places. The daemon reads it when it
+starts, so restart it after editing: `systemctl --user restart gamemoded`.
+
+The governor switch runs through polkit. Debian and Ubuntu only allow it for
+members of the `gamemode` group; without that, the daemon's journal shows
+`cpugovctl set performance: Not authorized` and the governor stays put while
+the session is otherwise active. Add yourself and log in again:
+
+```bash
+sudo usermod -aG gamemode "$USER"
+```
+
+Fedora and Arch allow any logged-in local user.
+
+Setting `performance.gamemode: on` accepts the pinning instead: `on` is an
+explicit request for GameMode, and Nightcap keeps the session whatever it does
+to the affinity. `off` never contacts the daemon.
+
+To see which CPUs the process may use:
+
+```bash
+taskset -pc $(pgrep -x mocktail)
+```
+
+## The main-thread pump
+
+Roblox posts its per-frame main-thread step at a time of its own choosing,
+and nothing signals the host when it does. The host main thread therefore
+polls `nativeCallMessagesFromMainThread`, and a post that waits more than a
+fraction of a millisecond costs a whole frame. Between polls the thread rests
+for 100 µs, and how it rests decides the CPU clock:
+
+| Mode | When | What it costs |
+| --- | --- | --- |
+| `sleep` | The governor is `performance`, which GameMode sets | The thread idles at about 3% of a core. The governor holds the clock. |
+| `tpause` | Otherwise, on a CPU with WAITPKG (Intel 12th gen and newer) | The core stays awake in a light C0 state. Frame rate holds; the OS books the time as busy, so the thread shows around 70% of a core, at lower power than a spin. |
+| `spin` | Otherwise | The core stays awake at full power. |
+
+Under a power-saving governor the CPU clocks a bursty core down unless some
+core stays awake, and Roblox's render thread then runs slower and drops
+frames. That is why `sleep` is not the default there. Startup prints the
+chosen mode:
+
+```
+  [main] engine pump rest: tpause (MOCKTAIL_ENGINE_PUMP_REST=sleep|tpause|spin)
+```
+
+`MOCKTAIL_ENGINE_PUMP_REST` forces a mode. `sleep` without the governor's help
+runs cooler for a few frames per second less; measure before keeping it.
+
+## Small texture upscaling
+
+`MOCKTAIL_SMALL_TEXTURE_UPSCALE` (default `4`) redraws ETC2 textures of 64px or
+smaller at N times their width and height. At the default that is 16 times the
+pixels per affected texture.
+
+The cost lands in two places. Decoding and resampling is CPU work on up to 8
+threads while textures load, which shows up as a burst rather than a steady
+load. The enlarged textures then stay in GPU memory for the session and cost
+extra sampling bandwidth on every frame that uses them.
+
+Set it to `1` to turn upscaling off:
+
+```bash
+MOCKTAIL_SMALL_TEXTURE_UPSCALE=1 mocktail
+```
+
+## Frame rate and present mode
+
+`graphics.frame_rate_limit` (default `-1`) leaves Roblox's own in-game
+framerate cap in charge; Nightcap sets no `DFIntTaskSchedulerTargetFps`
+override. A fixed value forwards that number to the scheduler.
+
+`graphics.vsync` (default `auto`) selects the presentation mode. `auto` and
+`on` both pick the lowest-latency synchronized mode the driver offers, in
+order: `FIFO_LATEST_READY`, `MAILBOX`, `FIFO_RELAXED`, `FIFO`. The first two do
+not block the render thread on the display refresh, so the frame rate is
+governed by the in-game cap rather than by presentation. `off` selects
+`IMMEDIATE` and does not synchronize at all.
+
+If the frame rate is higher than your refresh rate, the extra frames are work
+you cannot see. Lower the in-game cap to your refresh rate first.
+
+## Measuring
+
+Shift+F4 in game shows Roblox's own scheduler jobs, with a millisecond cost and
+a percentage for each. It does not show Nightcap's threads — the Vulkan
+adapter, the ETC2 decode workers, the libc shim — so it is a reading on the
+game, not on the process.
+
+For the whole process:
+
+```bash
+top -H -p $(pgrep -x mocktail)      # per-thread CPU, sorted
+ps -L -o psr=,pcpu=,comm= -p $(pgrep -x mocktail)   # which core each thread is on
+nvidia-smi --query-gpu=utilization.gpu,temperature.gpu,power.draw --format=csv
+```
+
+A thread pinned near 100% while the frame rate is steady is a busy-wait. The
+one exception is the host main thread in `tpause` mode, which the OS reports
+as busy while the core is parked (see above). Load spread across many
+`RBX Worker` threads is the game's own scheduler, and its cost tracks the
+place you are in — part count, moving parts and joints all show in the
+Shift+F4 World section.

+# Nightcap roadmap
+
+What Nightcap is working toward, in priority order. Items move to
+[Shipped](#shipped) when they land on `main`. Open an issue to propose a
+change to this list.
+
+## 1. Settings UI
+
+Nightcap is configured by editing `~/.config/mocktail/config.yaml`. Most
+people never open it, so they never find the FPS unlock or the vsync switch.
+
+Goal: a small GTK4 settings window, reachable from the app menu and from a
+`--settings` flag, that reads and writes the same `config.yaml`.
+
+- Graphics tab: backend, frame rate limit, vsync, small texture upscale.
+- Input tab: the `input.raw_mouse` toggle and controller options.
+- Advanced tab: FFlag overrides with a plain text editor for `fflags.json`.
+- Discord tab: every field in the `discord_rpc` block, so a friend can see
+  what you are playing and you can switch it all off in one click.
+- Changes apply on next launch. A restart button restarts Nightcap.
+
+Done when every option in `config/mocktail.example.yaml` that a player would
+touch can be set without a text editor.
+
+## 2. Controller button glyphs
+
+Upstream added Xbox and PlayStation gamepad support through SDL. Controllers
+already hot-plug and release their held inputs when unplugged. One rough edge
+is left.
+
+- Correct button glyphs for the connected pad. `SDL_GetGamepadType` is only
+  read for Xbox and PlayStation pads, so a Switch Pro, a GameCube pad, or any
+  generic pad SDL reports as `SDL_GAMEPAD_TYPE_STANDARD` reaches Roblox as
+  type 0 and draws generic glyphs. `SDL_GetRealGamepadType`, and the vendor
+  and product IDs, are available and unused.
+
+Done when a plugged-in pad shows its own buttons.
+
+## 3. First-load stutter
+
+The `--profile` trace now shows shader compiles and pipeline creation, so
+the stutter on first entering an experience can be measured.
+
+- Cut the stutter the trace shows, and prove it with a before and after
+  trace per [BENCHMARKING.md](BENCHMARKING.md).
+
+Done when entering a fresh experience no longer drops frames on shader
+compiles.
+
+## Shipped
+
+- Lower input latency: frames are presented as soon as they are ready.
+- Controllers hot-plug without a restart, and a pad that is unplugged mid-game
+  releases its held buttons and sticks instead of leaving them stuck.
+- Mouse look keeps responding after a long turn, instead of going dead until
+  the pointer travels back from past the screen edge.
+- Optional raw mouse input: `input.raw_mouse` in `config.yaml` sends look
+  deltas in host units, so fractional display scaling no longer changes
+  first-person sensitivity.
+- Small textures upscaled 4x by default, with PNG overrides in
+  `~/.config/mocktail/textures`.
+- ETC2 textures decoded on desktop GPUs without stutter.
+- No more error 319 kicks after joining a server.
+- Roblox sees the real host RAM and screen size.
+- Desktop launcher that works on Wayland and finds the installed binary.
+- Discord Rich Presence on by default, with the experience name, creator,
+  elapsed time, the experience icon with a Roblox badge, and a join button
+  when the server is public. See the [FAQ](../FAQ.md) to switch it off.
+- Custom Discord presence: title, details, state, and large and small icons
+  from `config.yaml`, with `{place_name}`, `{place_icon}`, and
+  `{creator_name}` placeholders.
+- `--profile` writes a Chrome-format trace of the Vulkan adapter's work,
+  including shader and pipeline creation, readable in `ui.perfetto.dev`.
+  [BENCHMARKING.md](BENCHMARKING.md) fixes the experiences to measure and
+  `scripts/summarize_profile_trace.py` builds the before and after table.
+- Texture uploads no longer stall the frame they land on: ETC2 decode and
+  resampling run on a persistent worker pool.
+- The host main thread rests between engine polls instead of spinning, and
+  GameMode's core pinning is released, so Roblox's workers spread across
+  every core. See [PERFORMANCE.md](PERFORMANCE.md).
+- Own app ID `io.github.CoderDayton.nightcap`, so Nightcap installs next to
+  upstream.
+- AppImage and signed Flatpak releases on every `v*` tag, with the Flatpak
+  repo on GitHub Pages.
+
+## Not planned
+
+- Replacing the `mocktail` binary and config names. Keeping them makes
+  upstream merges clean.
+- DEB, RPM, and AUR packages. Upstream ships those for unmodified Mocktail.

+  <h1>Privacy Policy</h1>
+  <p>Nightcap is a Linux runtime for the Roblox Android client. This policy covers Nightcap itself and its Discord application. Roblox and Discord have their own policies for the data they handle.</p>
+
+  <h2>What Nightcap collects</h2>
+  <p>Nothing. Nightcap has no server. It does not collect, store, or send telemetry, analytics, crash reports, or account data to the Nightcap project.</p>
+
+  <h2>What stays on your machine</h2>
+  <ul>
+    <li>Configuration in <code>~/.config/mocktail/</code></li>
+    <li>Session logs and support bundles in <code>~/.local/state/mocktail/</code></li>
+    <li>Roblox login session under <code>~/.local/share/mocktail/</code></li>
+    <li>Roblox cache, downloaded payloads, and shader cache under <code>~/.cache/mocktail/</code></li>
+  </ul>
+  <p>Flatpak installs keep the same layout under <code>~/.var/app/io.github.CoderDayton.nightcap/</code>.</p>
+
+  <h2>Discord Rich Presence</h2>
+  <p>When Rich Presence is on, Nightcap sends the current experience name, its public icon URL, elapsed time, and an optional public server join code to the Discord desktop client on the same machine over a local socket. Discord displays this on your profile under its own privacy settings. Nightcap never signs in to Discord, never reads a Discord token, and never contacts Discord's servers.</p>
+  <p>Set <code>integrations.discord_rpc.enabled: false</code> in <code>config.yaml</code> to turn it off.</p>
+
+  <h2>Roblox</h2>
+  <p>Nightcap talks to Roblox's services exactly as the Roblox client would. That traffic is covered by the Roblox Privacy Policy.</p>

vii	9e8afb233a	feat(discord-rpc): show the Roblox badge as the default small image Defaults images.small to the roblox_small asset on the bundled Discord application, with "Roblox" as its hover text.	2026-09-18 18:54:12 -05:00
vii	7fda1eb239	feat(discord-rpc): show the experience creator and title the card Roblox Default title is Roblox, details "Playing {place_name}", and state "by {creator_name}". The creator comes from the games API response already fetched for the place name. A text field that expands an empty placeholder is left out, so the state never shows a bare "by".	2026-09-18 18:45:11 -05:00
vii	f128e28b83	docs(perf): describe the main-thread pump rest modes and GameMode's governor permission	2026-09-18 18:26:32 -05:00
vii	718e67f9e1	perf(runtime): rest the engine pump between polls instead of spinning The main thread polls nativeCallMessagesFromMainThread 146k times a second with nothing to do. Between polls it now rests 100 us: nanosleep when the governor is performance, TPAUSE (C0.2) when the CPU has WAITPKG, a spin otherwise. Sleeping under a power-saving governor lets the render thread's core clock down and drops frames, which is why TPAUSE is the default there. MOCKTAIL_ENGINE_PUMP_REST=sleep\|tpause\|spin overrides. The profile trace gains a slice for pumps that ran a message.	2026-09-18 15:36:54 -05:00
vii	c6c354fdb1	perf(graphics): emit ETC2 uploads on the decode pool and stop the trace writer after a failed write EmitPass reuses the decoder's persistent workers through RunOnDecodeWorkers instead of creating and joining threads per batch. A failed trace write stops the writer thread rather than leaving it ticking every 250 ms.	2026-09-18 12:42:36 -05:00
vii	25930d14ff	fix(graphics, runtime): honor ETC2 source stride and cut main-loop overhead ETC2 uploads read bufferRowLength/bufferImageHeight instead of assuming packed rows. MakeFileObject retains the path field. The main-thread pump caches its JNI attach, but not the GetJNIEnv fallback, so a VM swap retries. An idle launch-broker drain skips both locks.	2026-09-18 12:21:29 -05:00
vii	65030d8df1	fix(input): hold the pointer position during relative mouse capture Relative-mode motion carries zero absolute coordinates. The router used to accumulate the deltas into its pointer position, so a long camera turn parked the reported position at the viewport edge and Roblox drew its cursor there when the capture ended. The position now stays where it was captured while deltas pass through. Zero-coordinate wheel and button events keep it too, and an unknown position defaults to the viewport center.	2026-09-18 02:51:03 -05:00
vii	0be5e808c5	fix(runtime): restore the affinity of every thread, not just the caller sched_setaffinity binds one thread, so the fallback that undid a GameMode pin only freed the thread that called Start(); the worker threads the fix exists to protect stayed on the daemon's cores. Walk /proc/self/task instead, and treat a readdir failure partway through as a failed restore rather than a finished one. Also stop chrome_trace_writer emitting a valueless "ts" on to_chars failure, or a bare inf/nan, either of which costs the whole trace instead of one field.	2026-09-18 02:00:58 -05:00
vii	1b030a57eb	perf(runtime, graphics): release core-pinning gamemode and parallelize texture uploads Release the GameMode request when the daemon narrows the CPU mask; the pin concentrates Roblox's worker pool and is re-applied every few seconds, so ending the request is the only thing that lifts it. `gamemode: on` keeps it. Emit texture uploads on worker threads instead of serially inside vkQueueSubmit, in two passes so mip 0 lands before the levels scaled from it. Decode ETC2 through a persistent pool and lower the parallel floor to one 128x128 image, so small batches stop running single-threaded. Document all three in docs/PERFORMANCE.md.	2026-09-18 00:47:57 -05:00
vii	2f5527b8b5	perf(libc_shim): cut path translation cost per file call Mappings are kept sorted longest prefix first, unmapped paths skip allocation, and the path trace switch is read once.	2026-09-16 21:22:31 -05:00
vii	579cedbf1d	perf(textures): pool ETC2 staging buffers and speed up resampling Staging buffers stay mapped and are reused instead of allocated per upload. Box resampling precomputes column spans and copies repeated rows, with identical output.	2026-09-16 21:22:31 -05:00
vii	a7b90e5919	fix(jnivm): stop leaking JNI handles until the table fills FindClass and GetObjectClass reuse one handle per class, detached threads release their local refs, and local ref deletes and singleton checks no longer scan. A full table logs the classes holding handles. Stale handles above slot 4096 no longer read as C strings.	2026-09-16 21:22:31 -05:00
vii	3bba795ea3	feat(profile): add --profile Chrome trace of Vulkan adapter work Records presents, GPU waits, submits, ETC2 decode, and pipeline and shader creation for ui.perfetto.dev. Adds a benchmark guide and a trace summary script.	2026-09-16 21:22:30 -05:00
vii	5ce4487d4f	feat(discord): add custom presence title, state, and icons text.title sets the activity name, images.* set the large and small icons and hover text, and text.state may be empty to hide it. Text and image fields expand {place_name} and {place_icon}; fields that render empty are omitted. show_place_name: false now also hides the place thumbnail.	2026-09-16 11:45:30 -05:00
vii	c544389dd0	fix(textures): make the crosshair arms symmetric Move the right and bottom arms out 1px so every arm reaches 12px from the center pixel with a 4px gap.	2026-09-16 11:11:06 -05:00
vii	bdb84142d7	docs(textures): ship a crosshair override people can copy in Adds textures/ with the crosshair PNG named by its ETC2 hash and a README covering install, naming and how to dump hashes for other textures. Nothing installs or loads it; copying into ~/.config/mocktail/textures is opt-in.	2026-09-16 04:53:53 -05:00
vii	40698efb7d	docs(changelog): release 0.2.0	2026-09-16 03:25:39 -05:00
vii	3d2a2b3d98	docs(changelog): record the input, storage, and packaging changes	2026-09-16 02:56:11 -05:00
vii	78a314b761	ci(packages): reduce to a branded nightly AppImage The workflow built DEB, RPM and pacman packages on every push to main and every pull request, then published them as "Mocktail continuous" with assets named Mocktail-* and a continuous tag pushed as komaruworld. Nightcap ships the AppImage and the Flatpak, so the three native package jobs are removed along with the APT and RPM repository step, which could not work here regardless: it downloads .deb and .rpm from this repository's latest release, and the release workflow publishes neither. What remains runs nightly and on demand rather than per commit, skips the build when the continuous tag already points at HEAD, publishes Nightcap-nightly-x86_64.AppImage with a checksum beside it, and tags as github-actions[bot]. A manual run from another branch builds and smoke-tests without touching the release.	2026-09-16 02:51:20 -05:00
vii	2d1dd3788b	ci(release): pass GH_TOKEN to the AppImage dependency installer install_anylinux_dependencies.sh now queries the GitHub API for the rolling release's asset IDs and digests. Without a token it uses the unauthenticated rate limit, which shared Actions runner IPs exhaust. packages.yml already passes the token; the release workflow runs the same script in the same container and did not.	2026-09-16 02:42:06 -05:00
vii	56d3160641	Merge upstream komaruworld/mocktail into main Takes upstream's AnyLinux dependency rework: the checked-in digest list is replaced by a name list, and the installer snapshots GitHub asset IDs and SHA256 digests together at build time, verifying each archive before installation. This removes the manual hash refresh `a998754` had to do. Keeps Nightcap's FAQ.md over the upstream copy; ours is the same document with Nightcap paths, RPC on by default, and the Discord play time section. Keeps TextureManager2 enabled rather than upstream's revert to TM1. Their mip regression is described on the mobile MipPackStream path, and this fork already reports real host memory and a PC device profile. Hours of play show no texture problem, so the workaround is not adopted without evidence it is needed here.	2026-09-16 02:37:08 -05:00
vii	5db99041bc	docs: rewrite the input roadmap items and trim the donation list Discord Rich Presence item 1 is custom presence fields; the private-server join item is dropped. The profiling item names the Chrome trace format instead of Perfetto. Item 2 covered hot-plug and input release on disconnect, which already work, so it is now only the button glyph gap. Raw mouse and the pointer fix move to Shipped. Drops the BCH donation address from the README.	2026-09-16 02:29:07 -05:00
vii	9ec56338c3	test: fix umask, dash, and scheduling assumptions in three suites native_update_test wrote approval artifacts with the process umask, which candidate_approval rejects when group writable. The helper now chmods 0600. webview_helper_launcher_test drove its fake helper with `dd <&198` under #!/bin/sh. dash rejects multi-digit file descriptors, so the script never ran and the packet file stayed empty. It now reads the control socket in python3, as the adjacent tests in the file already do. audio_foundation_test asserted the poller thread had run before stopping it, without waiting for it to be scheduled; it failed about one run in two. It now waits for the first poll under a bounded deadline.	2026-09-16 02:28:09 -05:00
vii	894ebf8eb7	fix(services): create BrowserTracker storage directories private and usable The service created its own credential directory with create_directories and then refused it, because IsPrivateDirectory rejects a group-writable path and mkdir masks its mode with the process umask. On a umask of 002 that failed every first run; a umask carrying owner bits left the directory unwritable by its owner instead. CreatePrivateDirectories creates each missing component and tightens it to 0700 through a descriptor opened O_DIRECTORY \| O_NOFOLLOW. Components that already exist keep their mode and are still judged by IsPrivateDirectory.	2026-09-16 02:28:02 -05:00
vii	6bec8a6c5c	feat(input): add input.raw_mouse and keep the pointer inside the viewport Relative-mode motion reports zero absolute coordinates, so the router accumulates deltas. The accumulator was never clamped, only the copy sent to the engine, so a long turn pushed it far outside the viewport and every reversal was swallowed until the pointer travelled all the way back. input.raw_mouse sends look deltas in host units instead of guest surface units. Those differ only when the desktop display scale and the window's pixel density disagree, as under fractional scaling. Default off.	2026-09-16 02:27:56 -05:00
vii	b9e7bc761b	docs(roadmap): swap RPC join items for custom presence fields Name the Chrome trace format for --profile instead of Perfetto.	2026-09-15 22:53:19 -05:00

vii	e1f7c8c06c	docs(changelog): add CHANGELOG.md and use it for GitHub release notes Release and Flatpak workflows take the release body from the tag's changelog section and fail early if it is missing.	2026-09-15 08:23:11 -05:00
vii	a9987546d5	fix(packaging): refresh AnyLinux debloated package hashes to 2026-09-15 pkgforge rebuilt six of the eight rolling packages, so the AppImage build failed on the ffmpeg-mini checksum.	2026-09-15 08:10:55 -05:00

vii	7cf24feef6	feat(branding): rename fork to Nightcap and add AppImage release workflow Show Nightcap as the app name in the desktop entry, window title, dialogs, and metainfo. Binary, config paths, and desktop ID keep the mocktail name. Publish Nightcap-x86_64.AppImage to GitHub Releases on v* tags. README points at the fork's releases instead of upstream packages.	2026-09-14 22:19:19 -05:00

vii	dd0655bfde	Merge branch 'pc-improvements' into main Resolve src/update/host_abi_deriver.cc: keep upstream's FMOD vtable layout versions and input-method derivation inside the optional output-device bridge, so a mismatch omits the bridge instead of failing derivation.	2026-09-14 16:09:33 -05:00
vii	d2d275706b	perf(graphics): present through fifo-latest-ready by default to cut input latency Roblox requests FIFO with 3 swapchain images, which queues up to two frames before display.
