• bytes command (Implement the bytes command #284)
• →Num and →Q (Implement ->NUM #255, Implement ->Q #282)
• if (Implement if-then-else #290) and iferr (Implement iferr #291)
• errm, errn, err0, doerr

• Add the glyph for the ⇄ sign and xth root (on ∜ in Unicode)

Bug fixes:

• Avoid null-dereference for out-of-range complex cos (Bug computing cos on complex values #253)
• Do not leave input argument for C->R and R->C conversions (Convertion from polar to rectangular does not drop argument #252)
• Fix display of "Seconds" marker in setup (Setup: display seconds toggle does not work #247)
• bignum: Read int values using correct endianness (Wrong endianness in bignum::value() #267)
• complex: More careful handling of angle units for polars (Conjugate gives wrong result for polar form #251)
• display: Do not display trailing digit separator after rounding (Regression in test for bug #116 #256)
• editor: Do not insert separators while typing symbols or text (Do not insert digit separators in symbols or text #260)
• header: Fix off-by-one in month name (Month name is off by one in header #248)
• help: Better scanning to find names with special Unicode characters (Help has trouble finding non-ASCII commands #286)
• logical: Check the type of stack level 2 (Bad type check on logical operations #272)
• modulo: Fix the case of -360 mod 360 (-360 mod 360 returns 360 and not 0 #264)
• settings: Default value for FractionSpacing is 5, not 3 (Do not emit FractionSpacing for default value 5 #261)
• state: Do not emit 'AutoSimplify' since it's the default (state: AutoSimplify incorrectly emitted to state file #257)
• state: Truncate state name for display (State name not correctly truncated #246)
• ui: Repair drawing of current command
• Allow xshift-ENTER to insert text while not editing (xshift-ENTER should work in non-alpha program mode #293)
• Multiplication by -1 had no effect (abusive simplification) (Multiplying by -1 does nothing #288)
• Argument of negative numbers should be pi, not 0 (Arg() returns zero for negative numbers #287)
• Emit error message for 0/0 (0/0 does not fail #279)
• Restore missing glyphs for atan2 and hypot (font: Lost glyphs for hypot and atan2 #295)
• arg for (1+i) returned a negative value (complex: Negative argument for 1+i #277)
• List + Text returns a list, not text (Text + List should return a list #297)
• Complex tan computation (Complex tangent result is wrong #300)
• Wiring of some missing menu entries (thanks @camillew)

Improvements:

• Change license to GPLv3
• doc: Add section about Unicode support
• doc: Change the level of sub-headings
• doc: Document changes regarding list
• state: display state file name on the right of date/time (Display the name of state file at end #258)
• tests: Run tests with default settings (Run the tests with default settings instead of custom ones #259)
• Rename graphics class to blitter
• Add 'make clangdb' makefile target
• Add documentation for arithmetic operations (+, -, *, /, ^)
• Expand documentation on autosimplify
• New SVG template contributed by @spiff72
