I’m excited to announce Hologram v0.5.0, a major evolution of the full-stack Elixir web framework! This release brings massive performance improvements - we’re talking execution times improved from milliseconds to microseconds in core client-side operations, making it fast enough for real-time interactions like mouse move events.

Key highlights:

- Complete bitstring rewrite with ~50x rendering speed improvements!

- Comprehensive session and cookie management

- Live reload functionality for enhanced DX

- Incremental compilation (2x-10x faster builds)

- New pointer and mouse move events

- HTTP-based transport layer

- CRDT support for future distributed features

Check out the SVG Drawing Demo that showcases smooth, responsive drawing using the new pointer move events - it really demonstrates the performance leap! https://hologram.page/demos/svg-drawing

With over 950 commits since v0.4.0, this release delivers significant architectural enhancements while maintaining the unique developer experience that makes Hologram special.

the performance increase is tangible - before, opening the hamburger menu on the site required a second or so, now it's fast enough to not notice

		The previous slowness was actually due to a temporary bitstring implementation we had in place. Now the full page renders at 60+ FPS, which is a massive improvement. And this is just the beginning - I'm working on component-level selective rendering that should make things an order of magnitude faster still. Instead of re-rendering the entire page, only the specific components that actually changed will be updated. It's exciting to see the performance gains become so noticeable in real usage. The hamburger menu responsiveness is exactly the kind of instant interaction that Hologram is designed to enable! :)
