build.yml runs git submodule update --init --recursive, but release.yml checked out only the top-level submodules. A submodule with its own submodules, such as Mbed TLS's framework in #3897, would leave the release configure step without them.
Build SDL's Wayland backend next to X11 and ask SDL for "wayland,x11"
on Linux, so the window runs natively under a Wayland compositor instead
of through XWayland. SDL loads libwayland, xkbcommon and libdecor at run
time, so systems without them, or sessions without WAYLAND_DISPLAY, keep
using X11. SDL_VIDEODRIVER still overrides the choice.

Since #5263 the Linux job restores a lavapipe shader cache keyed by the
runner's /proc/cpuinfo flags. llvmpipe compiles shaders with LLVM's host
CPU *name* (from vendor, family and model) plus the detected feature bits,
and keys its cache only by the feature bits, so two runners with the same
flags but different models share cached code. A hull shader JIT-compiled
on a znver4/znver5 or Ice Lake class host uses GFNI (vgf2p8affineqb);
loaded on a Zen 3 host with the same flags it raises SIGILL, which is what
agc_driver_tessellation has been hitting on main and on dispatched builds
since the first main build after #5234 saved that hull variant.
Hash vendor_id, cpu family, model and flags into the key, so a runner only
restores code compiled for its own CPU model, and print the model name so a
future mismatch can be read off the log.
The cache from #5107 was keyed by Mesa version only, so a runner restored
llvmpipe code compiled on another runner's CPU and about 85 agc tests died
with SIGILL (Illegal instruction) on main.

pr-overlap and area-labels walked every open PR on each run, spending the
1000 requests/hour that GITHUB_TOKEN gets per repository and starving the
other workflows (HTTP 403 'rate limit exceeded for installation').
pr-overlap keeps a hash of each report in actions/cache and only reads the
comments of PRs whose report changed. area-labels keeps head SHA plus the
labeler.yml blob per PR and labels only the changed ones, at most 40 per
run. conflict-label gets a concurrency group so pushes in a row don't stack
full passes.
tools/progress_history.py measures the first-parent history of main with
the rules of tools/progress.py, one point per day, and writes history.json,
history.svg and history.html. The Progress workflow runs it after
progress.py; the README shows the chart under the map and links the page.
Labels and points compact as days accumulate.

.github/ISSUE_TEMPLATE/performance.yml asks for the title and scene, what is
slow or what changed, the summary lines and traces of APS5_TRACE_FRAMES
captures, the trace digest and optionally the worker's collapsed stacks,
and states the capture protocol: warm caches, the same scene and settings,
no other profiling switch, the same machine and session. The pull request
template and CONTRIBUTING ask a pull request that claims a change in speed
for the summary lines of main and of the change, captured the same way.

The bundled SDL builds its PipeWire, PulseAudio and ALSA drivers only
when their development files are found, and otherwise keeps just the
silent dummy and disk drivers without an error. The Linux CI and
release jobs install none of them, so the v0.1.1 Linux libraries
(libSceAudioOut, libSceAgcDriver, libfmod) contain no audible driver.
Fail configuration on Linux when SDL found none of the three, install
the Debian development packages in the Linux build and release jobs,
and list the packages in the build instructions.
Authors with no merged pull requests can have 1 open, with at least 1
merged 20, and from 20 merged there is no limit. Reopening a pull
request runs the check again.

No job saved its ccache, so every build restored a day-old cache and
recompiled about half the tree (971/2038 hits). Main push builds now
save it, and they no longer cancel each other, so one finishes and
refreshes it. Pull request builds still only restore, so PR code never
writes the shared cache.
macOS has no counterpart to userfaultfd write-protect or
MEM_WRITE_WATCH, so GuestWriteWatch had no backend there and the driver
re-read every guest buffer on each use.
The macOS backend write-protects watched pages. The first write to a
page faults, the SIGBUS/SIGSEGV handler records the page and restores
its protection, and Collect reports the recorded pages and protects
them again. A page is protected before its record is cleared, under the
lock the handler takes, so a write that lands in between is recorded.
The lock hands out turns in order: an unfair one starved writers under
Rosetta.
The protection is real, which adds three entry points:
- GuestWriteWatchBeginHostWrite/EndHostWrite lift it around a system
call that writes guest memory, which would otherwise fail with
EFAULT. GuestArena::HostWrite calls them, as it calls the Windows
equivalent.
- GuestWriteWatchProtectionChanged tells the watch the protection given
to watched pages by mprotect or a new mapping.
- GuestWriteWatchProtection reports that protection, since a watched
page is read-only between a collection and the next write.
Register keeps the recorded protection of a page it already watches:
read from the kernel it would be the watch's own read-only protection,
and the page would never be watched again.
The tests build without the prx libraries and run natively and through
Rosetta.

Install lavapipe on Linux release builds and set ANYPS5_REQUIRE_VULKAN and GALLIUM_OVERRIDE_CPU_CAPS for ctest so GPU execution tests run instead of skipping. Scope SSL_CERT_FILE to Windows winlibs download and CMake configure steps only so Linux FFmpeg fetch is not broken. Leave release ctest as a single strict run.
Check out the repo when labeling open PRs so actions/labeler reads .github/labeler.yml locally instead of fetching it from the API once per pull request.
GitHub refreshes merge_commit_sha only when the pull request's branch
changes, so a manual build could test the pull request against a main
from days earlier. Each job now checks out main as it is when the build
starts and merges the pull request head into it.
gh label create exits non-zero for a label that already exists, and the
step runs with bash -e, so the first existing unforced label stopped the
job. Skip labels that already exist, keeping hand-set colors.
