Major Changelog will be posted when the alpha is released. We are working very hard on it to try and get it out by the end of this month.
Fixed major issues with character controller and swallow animation. Both of these were game breaking since January-March that were extremely complicated.
Dash works 100% now
Main Menu is functional and player prefs are saved
Loading Level screen is created and functional
Miu will 100% of the time catch the player unless he dashes away which uses a majority of stamina.
Thousands of minor improvements to UI, small snippets of code, cleanup, unused code removed, now using a different input system to support all controller types

These are major game breaking fixes that were fixed in the last couple days that heavily progressed game development towards the alpha.
The alpha will be released in waves. Each wave will bring a ton of new content, with a bunch of bug fixing in between until we meet our goal for release or 1.0 which will come especially with all the tremendous support we are receiving.

We are doing waves of content to further ensure high quality gameplay, and thorough bug testing from our supporters.

As for additional characters, content, alpha, hairstyles, hair color changes, customization, sound. Some will be presented in the first release but with potentially hundreds of different accessories to add it will take time to optimize.
Additional characters will come when they are ready. Since they have new internals, each one will take quite some time until all 5-6 characters are completed. It takes at least 4 months to stitch, and test all the internals to a new model and ensure no visual inaccuracies and that's after it's been completed.

The idea for waves are simple.
Month 1 will fix all critical bugs, and hopefully all small bugs.
Month 2 will be focused 100% on adding all the additional content for that content update. Since the foundation of the game will be there, big excitement for each wave :D
