internals: Add a changelog for the 0.4.1 release
In Nashville, in the work to get `primitives` out we rushed an
`internals` minor release that was actually breaking and should have
been a major release. For some reason at that time I omitted a
changelog, in hindsite now I look at the diff to `macros` I am not
surprised I missed the breaking change.
git diff internals-0.4.0 bitcoin-internals-0.4.1 -- internals/src/macros.rs
Add a changelog for the `internals v0.4.1` release. Note in it that
the release violated semver rules.
What changed, and why it matters
This commit only adds a changelog file documenting that a previous minor release (internals v0.4.1) accidentally included breaking changes and will be yanked. It changes no source code, build scripts, or runtime behavior. There is no security vulnerability here—just a documentation note about a semver policy mistake.
No security action needed. Treat as routine documentation/maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies internals/CHANGELOG.md to record that v0.4.1 violated semantic versioning by shipping breaking changes (MSRV bump, removal of impl_from_infallible usage, removal of impl_array_newtype) in a patch release, and that both v0.4.1 and v0.4.2 are being yanked. No executable code is altered.
