LogInLumberyard 1.22 is here, adding new features, improvements, and fixes.
First of all, there's the new asset dependency graph tracking which other assets a given asset depends on.
There's also a new command-line Asset Bundler tool to automatically pack assets for release with a game. You can basically save time on removing assets created during development but then removed from a game.
What is more, it adds several debugging features, including an experimental tool to analyze the memory used by each asset within a level, and more.
Users also get a new DevTextures Gem, a collection of textures for development and debugging.
