The v6.4.3_rel version was repeated in the cache path, cache key,
download URL and extract command. Define it once as a workflow-level
env var and reference it everywhere.
GitHub Actions caches are branch-scoped: an entry written by a
pull_request run lives under refs/pull/<N>/merge and is invisible to
other PRs. The haproxy, mbedtls, nss, ntp, threadx and hostap-vm
workflows used combined actions/cache with fixed keys, so every PR
re-saved its own copy of the same dependency, yielding one duplicate
cache entry per PR.
Split each into actions/cache/restore (always) plus actions/cache/save
gated to refs/heads/master, and add a daily schedule so a master run
reseeds the single shared entry that all PRs restore. mbedtls/nss save
in their build job only; the test jobs restore-only.
Disable the setup-msys2 package cache: the action only toggles caching
on/off and cannot save on master while restoring on PRs.
GitHub Actions now emits "Node.js 20 actions are deprecated" warnings:
actions are forced to Node.js 24 by default starting 2026-06-16, and
Node.js 20 is removed from the runners on 2026-09-16. Update every
JavaScript action referenced by the workflows and the local composite
actions to the lowest release that runs on Node.js 24:
actions/checkout v4 -> v5
actions/checkout (SHA pin) v4.1.7 -> v5
actions/upload-artifact v4 -> v6 (v5 still Node.js 20)
actions/download-artifact v4 -> v7 (v5/v6 still Node.js 20)
actions/cache[/restore|/save] v4 -> v5
actions/setup-python v5 -> v6
actions/github-script v7 -> v8
docker/setup-buildx-action v3 -> v4
docker/build-push-action v5 -> v7 (v6 still Node.js 20)
docker/login-action v3 -> v4
microsoft/setup-msbuild v2 -> v3
open-watcom/setup-watcom v0 -> v1
Actions already running on Node.js 24 (jwlawson/actions-setup-cmake,
shogo82148/actions-setup-perl, msys2/setup-msys2, dorny/paths-filter)
are left unchanged. These bumps are runtime-only; no workflow uses an
input or output removed by the new majors, and v4-format artifacts
remain compatible across the upload v6 / download v7 backends.
