A 9,000-module app that v0.11.1 couldn’t build at all now compiles, and mix compile with nothing changed on it takes about a second, down from 107. Struct code now loads when a struct of that type reaches the browser, which took that app’s runtime bundle from 5.6 MB to 660 KB, 133 KB gzipped in production. Plus prop validation, props readable in actions, and actions that run in the order they were dispatched. https://hologram.page/blog/hologram-v0-12
