Changelog

[v0.2.52] - 2026-03-29

Added multi-arch Docker image publishing via GitHub Actions, producing linux/amd64 and linux/arm64 images from a single workflow run. Pushes to main tag :development; version tags publish both :latest and the semver tag.
Added per-app custom HTTP headers so any additional headers (e.g. reverse-proxy auth tokens, vendor-specific headers) can be saved against an app and automatically merged into every outbound request Launcharr makes for that app.

All app API fetch paths now merge custom headers on top of their default auth headers, allowing custom values to override defaults where needed.
Docker CI build arg now correctly resolves to the semver tag on releases and development on main branch pushes.

No schema migration required.
Existing installs will gain the Custom HTTP Headers field in Settings → Apps → [any app] → Connection after upgrade.
Custom headers are opt-in and empty by default — no existing app config is affected.

Custom HTTP headers card appears in app connection settings form.
Headers saved persist across settings saves and are reflected in outbound app requests.
Docker image on Docker Hub shows both amd64 and arm64 manifests for v0.2.52.
Version string in Launcharr shows v0.2.52 (not vmain or vdevelopment) on tagged builds.
