The repo has no .gitattributes, so with core.autocrlf=true -- the default a Windows install sets -- every Go file checks out CRLF and `gofmt -l .` reports all 41 of them. There is no real drift; the tool just cannot see past the line endings. That makes the documented pre-PR check useless locally, and it hides genuine drift inside a wall of false positives. `* text=auto eol=lf` makes the working tree match what is committed. Verified: the same checkout goes from 41 files listed to zero, with no file content changing. pricing/defaults_gen.go is marked generated so it collapses in diffs. It is produced by `go run ./pricing/gen`, and reviewing a regenerated price table line by line is not a use of anyone's attention.
ROADMAP still told a reader that Config.EnablePromptCache was a flag waiting on langchaingo to expose cache_control. c84ce26 removed that constraint two weeks ago. The roadmap was therefore advertising the largest cost reduction in the library as unavailable -- HAL-546 fixed this same class of drift once already, and it recurred on the very next merge. Prompt caching moves into the status table as Phase 3c, with the measured numbers, and the note names Message.CacheBreakpoint so a reader knows what to reach for. The pricing bullet was half stale in the other direction: it claimed a regeneration job was still open when pricing/gen was added in 0c4550f. Only the schedule is missing, and now it says so. CONTRIBUTING, added alongside, makes roadmap review part of merging a feature rather than something to remember.
The next tag has to be v0.4.0, not v0.3.1, and nothing on main says so. PR #9 was authored as `feat(pricing)!:` because it changed the public Usage and Price structs, but the squash-merge took the PR TITLE as the subject and that title had no `!`. main reads `feat(pricing):`, with the marker surviving only inside the squashed body where nothing looks. A human cutting the release from the log would have read it as a patch. So three things, all pointing at that. CHANGELOG.md starts at 0.4.0 and leads with a Breaking section that shows Usage and Price before and after. Neither change is a rename or a removal, so named-field callers compile untouched and the break is invisible until someone's positional struct literal stops compiling -- which is exactly the kind of break that deserves a migration line rather than a mention. pricing.Compute and ComputeWithOK are recorded as deprecated, not removed. The rest of the release is the four independent ways cost was wrong (cache tokens uncounted, exact-match lookup pricing real model IDs at $0, missing usage reported as a priced zero, embedded rates drifted) and prompt caching finally doing something. CONTRIBUTING.md writes down the rule that was nearly missed: squash-merge discards per-commit subjects, so a breaking change must carry its `!` in the PR title. It also states the pre-1.0 versioning rule, that adding a field to an exported struct is breaking here, and that a release needs a changelog section before the tag. release.yml enforces that last one instead of trusting it. A Go module tag cannot be moved once the proxy has served it, so a release with no changelog section is not a mistake you can take back -- and pdftable shipped its v0.4.0 undocumented exactly this way. A grep is enough.
Reviewer's GuideThis PR prepares the v0.4.0 release by adding explicit changelog/versioning documentation, tightening release workflow checks, correcting roadmap/status docs for prompt caching and pricing, and ensuring consistent LF line endings via .gitattributes so local tooling behaves predictably.

Hey - I've found 1 issue, and left some high level feedback:
- The
.gitattributeschange appliestext=auto eol=lfto all files; consider scoping this to specific text extensions (e.g.*.go,*.md,*.yml) to avoid unexpected line-ending normalization of non-text assets. - The release workflow’s changelog check assumes headings exactly in the form
## [x.y.z]; if future changelog sections need qualifiers (e.g. prerelease labels or notes in the title), this grep will fail, so it may be worth either documenting that constraint explicitly or making the pattern slightly more flexible.

**suggestion (bug_risk):** Use fixed-string grep to avoid regex misinterpretation of version numbers.
Because `grep` runs in regex mode, dots in semantic versions (e.g. `1.2.3`) are treated as "any character" and can incorrectly match headings like `## [1x2y3]`. Use `grep -F` (or escape regex metacharacters in `${version}`) so the version is matched literally:
```sh
if ! grep -Fq "## [${version}]" CHANGELOG.md; then
...
fi
```
```suggestion
version="${GITHUB_REF_NAME#v}"
if ! grep -Fq "## [${version}]" CHANGELOG.md; then
echo "::error::CHANGELOG.md has no '## [${version}]' section"
exit 1

Use a literal changelog heading check.
The regular expression at Line 41 treats each . in ${version} as a wildcard. For example, ## [0x4y0] can satisfy the v0.4.0 tag. The release gate can therefore approve a non-matching changelog section.
Use a fixed-string, line-prefix check instead.
