GitHub will migrate the ubuntu-latest label to the Ubuntu 26 image between 2026-10-19 and 2026-11-19. This pins every tracked workflow to ubuntu-24.04 (supported for another two years) until the jobs are validated on 26.

  • 77 references across 58 workflows under .github/workflows/.
  • Includes matrix values (javase-cef-ffmpeg-smoke, linux-browser-link, linux-build-run, parparvm-parallel-mark, starter-canary, starter-launchers) and the runner chosen in a script for the scripts-fidelity-desktop gnome leg, whose screenshot baselines depend on the runner's fonts.
  • starter-canary reads its report artifact by canary-${{ matrix.os }}; the read(...) lookup is renamed in step.
  • Jobs whose names include the matrix value will show ubuntu-24.04 instead of ubuntu-latest. There are no required status checks on master, so no check names need updating.

Not changed: macos-latest/windows-latest, the vendored PaperMod theme's workflow, and the sample workflow in the initializr skill docs (that runner is the user project's choice).

GitHub is moving the ubuntu-latest label to the Ubuntu 26 image between
2026-10-19 and 2026-11-19. Several jobs depend on the exact image (apt
package names, the desktop session, and the font metrics behind the
fidelity screenshot baselines), so pin to 24.04 until 26 is validated.

Matrix values and the starter-canary artifact name that is derived from
matrix.os are renamed together so the report lookup keeps matching.

Compared 172 screenshots: 172 matched.
Native Windows port (x64 / Intel-AMD): full hellocodenameone screenshot suite rendered offscreen with Direct2D/DirectWrite, plus the real benchmarks (base64 native/CN1/SIMD, image createMask/applyMask/modifyAlpha/PNG/JPEG, SSE2 SIMD kernels). Compared against the in-repo baseline in scripts/windows/screenshots.

Metric Duration
SIMD kernel backend SSE2 (x64) / NEON (arm64) native kernels
SIMD int-add (64K x300) java 46ms / native 3ms = 15.3x speedup

SIMD kernel correctness PASS (native result == scalar reference)
Base64 native bridge unavailable (CN1 + SIMD + image benchmarks only)

Native Windows port, REAL shipping pipeline: the hellocodenameone screenshot suite rendered by a binary CROSS-COMPILED on Linux (clang-cl + xwin, WebView2 linked) and RUN on a Windows x64 runner. Compared against the in-repo baseline in scripts/windows/screenshots.

Benchmark Results

Detailed Performance Metrics

Metric Duration
SIMD kernel backend SSE2 (x64) / NEON (arm64) native kernels
SIMD int-add (64K x300) java 60ms / native 4ms = 15.0x speedup
SIMD float-mul (64K x300) java 58ms / native 4ms = 14.5x speedup
SIMD kernel correctness PASS (native result == scalar reference)
Base64 native bridge unavailable (CN1 + SIMD + image benchmarks only)
Base64 payload size 8192 bytes
Base64 benchmark iterations 6000
Base64 SIMD byte path gated to scalar (CPU autovectorizes scalar; explicit SIMD not beneficial here)

Native Windows port (arm64 / Apple Silicon - Arm): full hellocodenameone screenshot suite rendered offscreen with Direct2D/DirectWrite, plus the real benchmarks (base64 native/CN1/SIMD, image createMask/applyMask/modifyAlpha/PNG/JPEG, NEON SIMD kernels). Compared against the in-repo baseline in scripts/windows/screenshots.

Skip the legacy Android tools package in the AI cn1lib check
fa727eb 
android-actions/setup-android@v3 installs `tools` by default, which
cmdline-tools 16.0 on the current ubuntu-24.04 image no longer offers, so
the setup step fails before the job starts. Install platform-tools only;
the following step installs the platform and build-tools explicitly.
