Currently, the asset converter stores the openage nyan API as hardcoded nyan objects. It would be much better if the converter could read the API objects from the filesystem with a parser. There would be two ways to do this. Either we implement a new Python parser for nyan or we extend libnyan's already existing C+

We currently only have file decoders in d2fileformats. Most of the Load functions take a byte slice as an argument, and parse the bytes into a struct for that file type. We need to be able to convert a struct instance back to a byte slice.

Currently, if credentials are in use, they are authenticated in the master’s onUpdate method. For example:

https://github.com/boardgameio/boardgame.io/blob/9f6f80fda9f7b77ad7ac18c1dd2543e49463e4ae/src/master/master.ts#L198-L202

However, this is not the case for onSync or the new onConnectionChange (#839) methods, which presents a potential security flaw. If a match is using credentials

We moved from Jenkins to GitHub Actions for CI in amethyst/amethyst#2382 -- we wanted to ship that so we can get CI working in general for folks again. Here's a list of other things we would like to do soon. Please comment if you have more ideas!

Each item should have individual issue(s) and/or PR(s) opened for them. Let me know in a comment and I'll add a link next t

It would be nice to set a texture to tile or repeat on a mesh instead of stretch.

With #4150 merged we have a new model format: glTF ! This should be a much easier and long-lived format than the old md5 one. There are still some bits of cleanup and bugs to fix. Not necessarily all needed as part of this issue and some bits might be worthwhile to split out
