Cascadia Code 2008.25 Released (August 26, 2020) Website Download Spoiler: Changes 2008.25 This update to the Cascadia family of fonts brings the following changes: We are now generating static TTFs for every named variant These static instances will be hinted using ttfautohint, and so will look different than the variable font at small and intermediate point sizes We've temporarily stopped shipping variable OTFs due to some concerns about overlapping and psautohint The heaviest weight of Cascadia has been made a little lighter We have aligned the Powerline glyphs and the box-/line-drawing glyphs better to their metrics and to the letter glyphs Diacritic anchors have been added to all alphabetic characters (#282, #330) The font now ships with decomposed fi and fl ligatures The horn combining diacritic has had its weight fixed somewhat for Bold Primes have been redesigned to give them a more "angled" feel (#294) Acute and grave have been given additional weight to help differentiate them from dot (#268) The contextual alternate for x used to signify hexadecimal numbers has been disabled (#285)
As this is a Microsoft font I am disappointed that they don't make it easier to update. Having to manually remove previous copies and reinstall the updated version is far more tedious than it needs to be.
