ZakSync v0.1.0-alpha.4

Added

• Opt-in automatic update checks in Connection settings.
• Semantic release-channel handling: alpha builds can advance to newer alpha or stable releases, while stable builds ignore pre-releases.
• Verified in-place update installation and automatic restart.

Update security

• Release metadata is read from the public ZakovAU/ZakSync GitHub Releases API.
• Update assets must be named ZakSync.exe and include GitHub's SHA-256 digest.
• The downloaded executable is hashed before it can run.
• Update URLs must be HTTPS GitHub release URLs.
• Checks are limited to once every 24 hours unless the setting is newly enabled.
• The user is prompted before download, replacement, and restart.

Automatic replacement requires ZakSync.exe to be in a folder writable by the current Windows account.

Verification

• End-to-end tested by replacing alpha.3 with alpha.4 and confirming restart
• Replacement binary matched the verified package hash
• Settings dialog screenshot-checked
• GitHub Actions build and all 20 tests passed
• SHA-256: F021CC7C4101D6516DB76862BC02D9B3A25FC1D9EE0586E1EA162866B974E27B
