v3.0.0 (2024-05-28)

The first part of the version was increased from 2 to 3 to indicate a backwards-incompatible Node.js API change.

• Node.js API change: Packager#package()'s return object data property is now always a Uint8Array rather than being either a string or an ArrayBuffer. Depending on what you do with data, this might not actually break anything.
• Node.js API change: The packager now uses @turbowarp/jszip instead of the normal JSZip. It helps projects load faster. This doesn't break anything but it will may add an extra dependency to your tree.
• Added option to hide window controls
• Fixed running very large projects as HTML files in Chrome
• Fixed packaging very large projects as HTML files in Chrome
• Fixed window size for Electron apps using custom stage size
• Fixed error packaging projects that have variables with non-string names. These are technically invalid but sb3fix tolerates it

v2.0.0 (2024-04-07)

The first part of the version was increased from 1 to 2 to indicate a semver-major change. The license has changed from permissive-style to a weak copyleft, specifically the Mozilla Public License version 2. You can ask a lawyer to figure out what that means for you.

• Updated VM with new extension APIs, bug fixes, etc.
• Scratch font is back, sort of. It's been replaced with a new font that looks quite similar but without legal ambiguity
• Allow customizing behavior of escape key
• Fixed WKWebView apps
