The 0.21.1 to 0.22.0 changelog batch (#1112) landed on 2026-07-03. Four user-visible changes merged between then and the 0.22.0 release on 2026-08-11 never got an entry:

• Improve Meta overloads #700, overloads on the Meta stub, so type checkers reject mixing gt with ge and lt with le
• place null last in anyOf for optional unions in JSON schema #1028, null placed last in the anyOf generated for optional unions
• Fix __struct_encode_fields__ check in CI #1114, __struct_encode_fields__ added to src/msgspec/__init__.pyi (its companion Add __struct_encode_fields__ to type stub #813 only touched tests/typing, so it needs no entry of its own)
• Fix json.encode of a dict keyed by a plain str Enum #1118, json.encode raising TypeError for a dict keyed by a plain str-valued enum.Enum

I went over every PR merged in that window. The rest need no entry: #813 and #1117 are tests only, #1121 fixes an unreleased regression from #1028, #1145 is an unused variable under free-threaded builds, and #1146 and #1148 are CI and tooling. #1127, #1135 and #1080 already have entries.

Docs build clean with --fail-on-warning.

Note for whoever retries the release: the section is still headed Version 0.22.0 (2026-08-11), and that date will need updating, since the tag was deleted after the upload failed. Refs #1134.
