   - COMBINING LONG DOUBLE SOLIDUS OVERLAY (`U+20EB`).
 * Generate TTFAutohint control files for better glyph display for variant glyphs (#1963).
 * Make the shape of motion-serifed and serifed variants of toothed/tailed `u` no longer identical under Italic. Now "serifed" `u` will always preserve all serifs (#1967).
+* Make the fully-serifed form of cursive lower `y` match the serifs of lower `u`.
 * Make MICRO SIGN (`µ`) tailed under italics by default, to match `u`.
 * Improve glyphs for COLON SIGN (`U+20A1`), GUARANI SIGN (`U+20B2`), and CEDI SIGN (`U+20B5`).
