Won't work due to technical issues.

DISCLAIMER

This is a testing build of new IAS v9. It has some bugs (probably) and if you will rollback to v8, you will have to readd your accounts.

What's new in 9.0.0

• Rewritten all code from the ground up using modern Java (17) and modern Minecraft API. (Probably fixed some bugs and added some more due to this)
• Refactored the project to allow easier cross-loader and cross-version development.
• Added access/refresh token encryption with hardware or password key at your choice. (To combat token stealing and accidental token sharing; It's possible to opt-out of token encryption but it's UNSAFE and is disabled in the config by default)
• Added a lot of things to prevent token stealing and accidental token sharing. (Encryption mentioned above; Moved accounts out of config folder; Added disclaimers and "loud" file names into the new folder; Added info on how to "revoke" all tokens)
• Added Forge, NeoForge, and native Quilt support.
• Some authentication errors will now use more detailed/helpful messages.
• Authentication link will be now copied to clipboard.
• Improved security and fixed some bugs for Microsoft authentication. (Also added alternative authentication method similar to MultiMC/Prism)
• Used new skin widgets (used for skin reporting by Mojang) to preview skins.
• Added an option to show nick in the server list. (Enabled by default; Can be disabled)
• Enabled button in the server list by default. (Can be disabled)
• Auto-moving IAS button to the right if there's another mod button in the way.
• Added a lot of various tooltips.
• Prevent invalid offline names (too long, too short, containing invalid characters) by default. (Can be overridden)
• Added toast notification (warning) for invalid offline names when joining a server. (Can be disabled)
• Added an option to show current username in the game title bar. (Disabled by default)
• UI was rewritten. (Main UI is mainly untouched; Account adding/removing/editing/using screens remade into "fluent popups"; Config UI is changed slightly; Keybinds will work in some GUIs; Double clicking an account will use it; Accounts will show tooltips)
• Added a few unexpected pigs. (easter eggs)
• Added some help pages.

• Added 1.19.2 and 1.20.2 support.
