Version 0.6.0.

Why

• The precompiled NIFs now bundle FFmpeg 9.0.1 (was 8.1.3).
• exmpeg builds on our rubas/rsmpeg fork. The fork supports FFmpeg 9 and has the AVChannelLayout fix, so the copy_ch_layout workaround is gone.
• Source builds (EXMPEG_BUILD=1) now need FFmpeg 9. This breaks source builds against FFmpeg 8, so this is a minor release.

The 0.5.0 entry in CHANGELOG.md stays as it is. Its Hex publish still waits for the owner.

Included PRs

• chore: update NIF checksum for v0.5.0 #80 chore: update NIF checksum for v0.5.0 (no changelog line)
• chore: mark the channel layout workaround for removal #81 chore: mark the channel layout workaround for removal (no changelog line)
• feat: build on FFmpeg 9.0.1 through our rsmpeg fork #82 feat: build on FFmpeg 9.0.1 through our rsmpeg fork

What changed

• mix.exs: @version "0.6.0".
• CHANGELOG.md: new 0.6.0 entry from the Changelog section of feat: build on FFmpeg 9.0.1 through our rsmpeg fork #82, checked against its diff. The file had no Unreleased section.
• README.md: the install snippet is now {:exmpeg, "~> 0.6"}. No other doc names the version.
• checksum-Elixir.Exmpeg.Native.exs keeps the v0.5.0 entries. Step 3 of RELEASE.md replaces them after the release workflow tags v0.6.0.

Decisions

• The 0.5.0 entry says that rsmpeg resolves from crates.io and that a source build no longer fetches from GitHub. feat: build on FFmpeg 9.0.1 through our rsmpeg fork #82 made that untrue. The brief keeps the 0.5.0 entry as it is, so the 0.6.0 entry states the reversal.
• The removal of copy_ch_layout is not in the changelog. Callers see no change: the 0.5.0 fix for the channel layout crash stays in effect through the fork.
• The commit uses the chore: release X.Y.Z style of release: 0.5.0 #78. The PR title follows the brief.

Checks

With . /tmp/elixir-sweep/exmpeg-env9.sh (Arch system FFmpeg 9.0.1, libclang 20, EXMPEG_BUILD=1):

• task check: green (format, compile --warnings-as-errors, credo strict with no issues, clippy -D warnings, 43 Elixir unit tests, 17 Rust tests, zizmor with no findings).
• task test:integration: 104 passed.
• No dprint.json in the repository, so dprint fmt did not run.

Review findings for the 0.6.0 release:

• Opus, CHANGELOG.md line 16, Exmpeg.version/0 does not report FFmpeg 9.0.1: fixed in 950b9a1. The entry now names the library versions that Exmpeg.version/0 returns: avformat and avcodec 63.x and avutil 61.x (was 62.x and 60.x). A local build against FFmpeg 9.0.1 returns 63.1.101, 63.1.101, and 61.1.101.
• Astra, CHANGELOG.md line 16, the same finding: fixed in 950b9a1.

task check passes on 950b9a1.
