Keeping PyReconstruct Up to Date

Keeping PyReconstruct Up to Date

The frozen Windows and macOS one-click builds can update themselves from within the app. The updater downloads the new build from GitHub Releases and verifies it against a published SHA-256 checksum before installing — if the checksum can't be reached or doesn't match, nothing is installed. (The Linux .sh installer updates by re-running install.sh — see Installing PyReconstruct.)

Update channels

PyReconstruct offers two update channels, selected under Series ▸ Options… (Shift+O) in the Updates section:

• Release (recommended) — stable builds, tagged vX.Y.Z.
• Pre-release (experimental) — the latest pre-release build (release candidates, tagged like vX.Y.ZrcN); newer features, less testing.

The default channel is Release.

Checking for updates

Choose Help ▸ Check for updates…. On an installed build, PyReconstruct checks GitHub Releases on your selected channel (off the main thread, so the UI stays responsive). If a newer build is found, an update dialog opens showing the new version, the download size, and the release notes, with a Download & Install button. The download is verified, then applied when you close the app, and PyReconstruct restarts on the new version.

If you are already current, you'll see a brief "You're already up to date" message; if no installer exists for your platform on that channel, it tells you so.

Checking automatically on startup

Under Series ▸ Options ▸ Updates you can enable Check for updates on startup. It is off by default. When enabled, an installed build does a quiet background check at most once per day; if an upgrade is available it shows a status-bar notice and asks whether you'd like to view it.

Source / pip installs

For a from-source install, Help ▸ Check for updates… instead reinstalls PyReconstruct from a chosen Git branch with pip and then restarts. The branch is configured under Series ▸ Options ▸ Updates (the Branch: field, default main). The channel/installer machinery above applies only to packaged builds.
