Development News  

New logo and further website refresh

The logo received a refresh, dropping "Hb" characters, making it fit in a square shape and refreshed, fewer colors. The website evolved further as well, with brighter and more modern look, larger fonts, responsive design and a new Donate button.

Website refresh

Continuing with the refactor, the site is now fully vector-based, sources have been cleaned up and further minimized, the look refreshed. The crew page and code examples are now automatically generated, thus much easier to update. Several pages have been converted to Markdown. Source size is now 64 kB (was 624 kB). Also added en edit button to each page.

Website refresh

Website refactored to use Jekyll, use pure HTML5, drop table based layout, drop JavaScript for a CSS menu, remove anything unused, fix things broken, use vector images instead of bitmaps where possible, deduplicate markup and content. This means 7.5x size reduction of page sources.
Content and design remained the same, but much easier to update now.
