This update to the Cascadia font family brings the following changes:

• The full control pictures block has been added (u+2400 to u+2426). For purposes of rendering, the two letter abbreviations have been used instead of the standard three letter abbreviations (#219)

  • 
  • Additionally, ss20 includes the oft-unused graphical representations of these codepoints (for fun!)
  • 

• Full support for Fira Code's current ligature set (with a few exceptions). Now featuring infinite arrows!!! (#276)

  • 
  • This involved a full refactoring of the calt feature—for those interested, it now uses forward-looking substitutions instead of backward-looking substitutions and progressive substitution to reduce code. This also required some redesigning of the greater / lesser related ligatures. Please note, I have also removed all the obsolete ligatures now covered by the arrows code.

• There was a mismatch in the font's postscript naming conventions that was corrected. Should now render all weights in Word. Note there is apparently an additional bug in Mac Word's implementation of variable fonts which should be available in an update mid-Feb. (#329)

• Reworked the hints for the mod and superscript glyphs so that they're bottom-up rather than top-down. This allows for better bottom alignments.

New Glyphs

• ⏎ (#262)
• additional codepoints for control characters U+21B2, U+2771, U+2770, U+2423 (#264)
• U+211E ℞ (#324)
• U+2302 HOUSE (#359)

New Ligatures

• !: and !. added (#281)
• /\ and \/ added (#290)
• ??= added (#301)
• <:> and other variants implemented via the calt (#327) refactoring

Changes

• Added x-height instruction into ttfautohint to control the (#371) height of the lowercase.
• Completely redesigned quote marks for better recognition (#375)
  • 
  • Note: this only applies to curved/smart quotes
• updated hinting to achieve more consistent results (#377)
• increased height of thetamod (#381)
• reduced the width of the hooklefts (#382)
  • 
• updated heights on esh, glottalstop, glottalstopreversed (#383)
  • 
• tweaked hinting a little bit (#384)
• added remaining soft-dotting (#386)
  • 
• changed designs of the angled quotes (#392)
  • 
• changed former ~= symbol to a simpler component-based (#394) version. Should be less confusing now for Lua / Matlab users.
• made the underline thicker based on font weight (#395)
  • 
• increased size of degree (#400)

Aside from the above changes, this version also includes many other small updates including spacing, outline quality improvements, and fixing hinting.
