build(ci): drop macos-15-intel from the test matrix#39
Merged
Conversation
release.yml stopped producing native x86_64 macOS binaries in e3a4d28 — cargo-packager's create-dmg step bombed on the macos-15-intel image with no recoverable diagnostic, and the fix was cross-compiling x86_64 macOS from macos-26 alongside the native arm64 build. CI was never updated to match: it kept testing natively on macos-15-intel while release shipped the cross-compiled output. That's the worst of both worlds — we test one path and ship another with no overlap. The native-x86_64 CI run only verifies "the code that would have been built natively works," not "the cross-compiled output we actually distribute works." This commit takes the consistent stance: both CI and release are Apple-Silicon-only on macOS. Drops the macos-15-intel matrix entry, updates the inline comment to link the decision back to e3a4d28's release-side rationale, and notes the path back if native Intel builds ever return (unlikely given Apple's transition timeline and GitHub's macos-15-intel sunset schedule). Saves ~5–7 min per CI run on a path that wasn't providing shipping confidence anyway. No x86_64-specific code in the tree (no SIMD, no arch-gated cfg, no x86-only deps that aren't well-tested upstream) so the loss of native-x86 coverage is low-risk.

Moves the DXGI probe entry from [Unreleased] into a versioned [0.13.0] section dated today (the day all four PRs landed on main: #38 audit + probe, #39 macos-15-intel drop, #36 gpui bump that subsumed #37 gpui_platform bump). Adds a [Changed] entry for the gpui upstream-rev bump. Per CONTRIBUTING.md, dev-tool / internal-refactor changes stay out of CHANGELOG — the file splits, cargo-deny, workflow_dispatch, fmt + scripts CI gates, Tauri-residue deletion all land in the audit but don't surface to users beyond "things compile + run as before." git log carries the per-commit detail for anyone spelunking; the CHANGELOG entry is what shows up in the GitHub Release body. The release date is set to today (2026-05-24) since that's when the v0.13.0 content was finalized on main. If the stable tag lands days after the beta, the date can be bumped — but since all content is already merged, today is the accurate "this is what the release contains" anchor.

Why this is a separate PR
This commit was originally part of #38's audit branch but landed on the branch ~32 minutes after #38 was merged, so the squash-merge didn't pick it up. Cherry-picked clean onto a fresh branch off
mainto avoid the 28-commit re-PR confusion that'd result from re-opening from the original branch (whose history no longer shares ancestry with main's squashed equivalent).Test plan

Low. No x86_64-specific code in the tree (no SIMD, no arch-gated cfg, no x86-only deps that aren't well-tested upstream).
