No Cpp2IL release reads Unity 6.5's metadata yet ("We support 23-106, got 107"), so the text-field and MSAA
fixes were skipped for Wander 0.3570 (#198). When the release reports an unsupported metadata version, the
development branch's CI build (nightly.link, as Cpp2IL's README links it) is fetched into tools/cpp2il-nightly/
and used; cached errors of that kind get one retry with it. Checked with Wander 0.3570: it reads the v107
metadata and writes TMP_InputField, OVRDisplay and OculusLoader.
