, this time covering some war stories from the past 12 months of getting Tiliqua hardware ready to ship, and all the new features added to the DSP/RTL library since then. Well cover some fun topics such:

* Dynamic frequency scaling for display switching
* New DSP cores and example projects
* How we are adding first-class fixed-point types to the Amaranth language
