AtlasToolkit v0.3.1

AtlasToolkit v0.3.1

Patch release focused on reliable silent self-update for installed Windows builds.

Installed builds from v0.3.0 can update in-app via Restart to Update. Portable builds still link to the releases page.

Self-update fixes

• Run the Inno Setup installer directly from the app (not via PowerShell) to avoid Windows Open File - Security Warning on signed installers downloaded to %LocalAppData%\AtlasToolkit\update\
• Remove Mark-of-the-Web (Zone.Identifier) after downloading the update installer
• Drop AppMutex from the installer script so silent /FORCECLOSEAPPLICATIONS can shut down the running app instead of aborting with /SUPPRESSMSGBOXES
• Use /FORCECLOSEAPPLICATIONS and a hidden relaunch watcher script to restore command-line arguments (e.g. opened .atlas files) after install
• Detach the update process tree with ShellExecuteW so the app can exit cleanly before Inno closes it

Installer

• SetupMutex still prevents concurrent installers; interactive [Run] launch unchanged

v0.3.0

AtlasToolkit v0.3.0

Major release — new UI, multi-page atlas support, Windows installer, and a full codebase refactor.

Migration from v0.2.2: Windows builds now ship as an installer (AtlasToolkit-Setup-x64.exe) plus a portable zip. If you used the old single-exe auto-update, download and run the installer once — older builds report "asset not found" when checking for this release.

UI overhaul

• Redesigned layout with an app bar and separate View / Edit modes
• Save image — export the current preview as a PNG
• Modular frontend — split the monolithic script.js / style.css into focused JS and CSS modules
• Multi-page atlas page switcher with per-page preview
• Missing-page modal when a referenced atlas page image is not found
• Preview cache for faster re-renders when switching pages or modes
• Drag-and-drop debounce to reduce flicker during file drag-over
• --debug CLI flag for troubleshooting

Multi-page atlas & modify mode

• Full multi-page repack pipeline (repack_multi_page) wired through modify mode
• Page switcher UI and preview API for atlases with multiple .png pages
• Repack toggle hidden in multi-page modify mode (not applicable)
• Full-canvas merge, sequential mod application, and repack toggle fixes

Atlas correctness

• Ported atlas parsing/rendering fixes from the js-project branch (offsets, rotation, page detection, and related edge cases)

Windows distribution & installer

• Nuitka onedir standalone build instead of a single bundled exe
• Inno Setup per-user installer — no admin / UAC required
• Fixed install directory (%LocalAppData%\AtlasToolkit) for reliable silent self-update
• Optional .atlas file association — open atlas files directly in the app
• Installer mutexes, version info, clean upgrade via previous-version uninstall, quick-launch shortcut
• Portable zip (AtlasToolkit-Windows-x64-portable.zip) still available for non-installed use

Self-update

• Installer-based silent self-update (installed builds only; portable links to the releases page)
• Revamped update flow with helper fallback and recovery UX
• Improved relaunch after update — multiple launch strategies, env-var preservation, delegated .old cleanup with retry

Codebase refactor

• Python code reorganized into the atlas_toolkit package:
  • atlas/ — extract, modify, repack, format conversion
  • core/ — document model, overlay, region operations
  • app/ — pywebview bridge, session, launch, preview cache
  • update/ — GitHub release check and update controller
• Removed legacy monolithic modules (atlas_modifier.py, atlas_extracter.py, updater.py)

Other

• README updated with link to the web version
• CI: Inno Setup build step, portable zip artifact, manual test builds no longer create accidental releases

Full Changelog: v0.2.2...v0.3.0

v0.2.2

• Fixed atlas page detection to avoid misreading region names as page images
• Hardened update notification rendering to reduce injection risk
• Fixed missing offsets handling when updating atlas text
• Added guard for empty selected regions in modifier flow
• Included minor reliability improvements and internal cleanup

Full Changelog: v0.2.1...v0.2.2

v0.2.1

🐛 Fixes

• Missing rotate in atlas output — Fixed a bug where the rotate property was not written to the atlas text when the original atlas didn't have a rotate: line, but the merged region required rotation (e.g. 90°)
• Incorrect bounds after rotation — Fixed atlas bounds being incorrectly swapped after rotation; Spine atlas format requires bounds to always store original (pre-rotation) dimensions

Full Changelog: v0.2.0...v0.2.1

v0.2.0

✨ New Features

• Atlas format converter — Automatically converts LibGDX atlas format to Spine format, enabling support for LibGDX-based atlas files
• Auto-update checker — Automatically checks for new releases on GitHub at startup with a slim notification bar
• Persist repack preference — Repack checkbox state is now saved across sessions via config file
• Version display — App version is shown in the window title

🔧 Improvements

• Code signing — CI pipeline now supports executable signing
• Atlas text cleanup — Cleaner atlas text reconstruction matching standard Spine format

🐛 Fixes

• CI: version resolution — Fixed manual builds incorrectly showing branch name as version; now falls back to pyproject.toml

📦 Dependencies

• Added requests for update checking
