Here are the most notable changes in each release. For a more detailed list of changes, see the Github Releases page.

The default path of the scratch file has changed. The first time you start the new version of Heynote, your existing buffer file will be migrated to the new note library. If you're using the default buffer location, that means that the existing Scratch buffer file will be moved from %APP_DIR%/buffer.txt to %APP_DIR%/notes/scratch.txt. If you are using a custom buffer location the existing scratch file will be moved from %CUSTOM_DIR%/buffer.txt to %CUSTOM_DIR%/scratch.txt. Before the migration, the existing buffer file will be backed up to %APP_DIR%/buffer.txt.bak or %CUSTOM_DIR%/buffer.txt.bak.

If you are running a previous version of Heynote with the buffer file synchronized across multiple machines using a file synching service such as Dropbox or OneDrive, you should make sure to upgrade all machines to Heynote 2.0 at the same time (closing Heynote before) in order for the file to stay in sync, since the file path for the buffer file has changed.

Apart from the default Scratch buffer, you can now create and switch between multiple note buffers. Ctrl/Cmd+N opens up a dialog for creating a new buffer. By pressing Ctrl/Cmd+S you can create a new note from the current block (the current block will be moved into the new note). New note buffers are saved to the note library which is basically a directory (with sub dirs) on the disk with a .txt file for each buffer. You switch between buffers by pressing Ctrl/Cmd+P.

• The file format for the buffer files has been updated to include some JSON metadata at the top of the file.
• The cursor(s) location is saved between sessions.
• Improvements when using a file syncing service (e.g. Dropbox, OneDrive) to sync the note library between machines.
• The setting for changing the color theme is now located in the program settings, instead of in the status bar.

• Performance optimizations
• Add default redo cmd that works on all Platforms. Mod+Shift+Z
• Fix bug causing editing to break for empty blocks in some cases
• Add setting for configuring the default block language
• Vue language support
• Dart Syntax
• Fix error on startup for large buffers

• Added support for having Heynote in the Mac Menu Bar / Tray icon
