 - The docs sidebar outline now lists `h3` headings as well as `h2` — per-flag and per-pattern detail (27 headings on Command line, 24 on Common patterns, 23 on Coverage) was hidden from the "On this page" navigation
 - The `--parallel` unsupported-OS warning no longer claims Alpine is excluded: Alpine has been a supported parallel platform since the race conditions were fixed, the message was simply never updated
 
+### Removed
+- `bin/create-pr`, a 476-line vendored copy of [Chemaclass/create-pr](https://github.com/Chemaclass/create-pr) v0.10. Nothing referenced it — not the `Makefile` targets, the workflows, or the docs, which link the upstream project rather than this copy — and having no `.sh` extension it escaped `make sa` until #863, so it sat in the tree written in a Bash 4 style the project's own rules prohibit. Use the upstream tool (#867)
+
 ### Fixed
 - `--parallel` no longer discards stderr written inside a worker but outside a test body, which made the same run report differently depending on the mode. Each file worker had been spawned with `2>/dev/null` since #358 to keep its noise off the progress line; its stderr is now captured per file and rendered afterwards as a `Stderr from <file>` block, so data-provider diagnostics, hook-plumbing messages and scratch-dir errors survive. Output written by a test *body* was never affected — it is merged into that test's captured stdout and already appeared in its failure block (#864)
 - The minimum-bash gate now compares the minor version as well as the major, so it enforces whatever `BASHUNIT_MIN_BASH_VERSION` declares. It previously accepted any `3.x` regardless of the stated minimum, and a version string carrying a suffix (`5.2.37(1)-release`) is now parsed instead of tripping the comparison. The floor itself is unchanged at **Bash 3.0+**; `printf -v`, `+=` and `[[ =~ ]]` are now rejected in `src/` by the compatibility gate, since 3.0/3.1 lack the first two and 3.2 changed quoted-pattern semantics for the third
