Language

• Breaking Change - un ° fix ¤ now does pattern matching
  • under ⍜ fix ¤ retains the old behavior
  • Collapsing the top two dimensions of an array can still be done with reduce /join ⊂
• Breaking Change - un ° on ⟜ now does pattern matching in some cases
  • This makes its bevahior conform to the rule that a function's inverse must have the opposite signature
  • Some other cases, such as °⟜+, now properly invert the function
• Breaking Change - keep ▽ with a scalar counts array now copies each row that many times
  • This matches the behaviors of APL and BQN, and is generally more useful
  • The old behavior can be achieved with /⊂↯
• Breaking Change - fill ⬚ values are no longer accessible through function calls
  • This makes it harder to accidentally use a fill value without meaning to
  • This does not affect un °pop ◌
  • This can be circumvented with fill ⬚un °pop ◌
• Stabilize by ⊸!
• Stabilize repr
• Add experimental stack swizzles, which allow for more flexible stack reordering
  • Swizzles are written with a λ followed by a list of letters
  • Capital letters fix ¤ the corresponding value
  • The λ formats from ' when it is in front of the letters
• Add experimental array swizzles, which allow extracting rows from an array in a concise way
  • Swizzles are written with a ⋊ followed by a list of letters
  • Letters up to m start from the first row, Letters back from z start from the last row
  • Capital letters un ° box □ the corresponding value
  • The ⋊ formats from '' when it is in front of the letters
• keep ▽ now works with un °
  • It splits an array into counts and an adjacent deduplication
• Add the json function, which encodes and decodes JSON strings
• Add the xlsx function, which encodes and decodes XLSX data
• bits ⋯ can now take negative numbers
• un ° bits ⋯ can now take non-booleans
• Add un ° duplicate . pattern matching
• Add un ° min ↧ and un ° max ↥ pattern matching
• insert can now be used with un ° to extract a map entry and pattern match it
• fill ⬚ed keep ▽'s fill value may now be a list
• infinity ∞ can now be passed in a list to take ↙ or drop ↘ to take/drop every row along an axis
• reduce / can now take a function with more than 2 arguments
  • Each additional argument increases the number of arguments passed to reduce / by 1
  • Additional arguments are passed to the function on every iteration
• try ⍣ signature checking is now more permissive
• Switch function signature checking is now more permissive with branches that have an assert ⍤ that always triggers
• first ⊢, first ⊢ reverse ⇌, rise ⍏, and fall ⍖ can now be used on scalars
• Add the &exit system function, which exits the program with a status code
• Add the experimental &memcpy system function, which copies the data from &ffi pointers to an array
• Add the experimental &memfree system function, which frees memory allocated by &ffi functions
• Add &tlsc and &tlsl system functions, which allow making TLS connections
  • &tlsc replaces &httpsw, which is now deprecated
  • &tlsl is currently experimental and mostly untested
• &rs will now attempt to read additional bytes to resolve a UTF-8 character
• [&gife] and [&gifs] now support binary transparency
• Signatures can now be specified in stack array notation immediately after a [ or {
• Change how long decimal numbers are formatted
  • Sequences of repeated digits are now replaced with …
• Add argument documentation comments
  • You can read more about this in the new Documenting Code tutorial
• Add some useful shadowable constants for working with compile-time file paths
  • ThisFile - The relative path of the current source file
  • ThisFileName - The name of the current source file
  • ThisFileDir - The directory of the current source file
  • WorkingDir - The compile-time working directory
• Deprecate function strands
  • They ended up making code less readable
• Remove previously deprecated primitives:
  • this ↬
  • recur ↫
  • all ⋔
  • cascade ⪾
  • bind λ
  • types
  • shapes
• Remove several backward compatibile glyphs from the lexer
  • This frees up some glyphs that can now be used as function names

Interpreter

• Lots of optimizations
  • Optimize the pattern /F⊞F to use much less memory and be an order of magnitude faster in some cases
  • Optimize group ⊕ and partition ⊜ with length ⧻, first ⊢, and first ⊢reverse ⇌
  • Optimize iterating modifiers with a top-level fork ⊃ or bracket ⊓
  • Optimize ≡⋅constant and ∵⋅constant patterns
    • The speed improvement is on the order of 70x
  • Optimize the pattern [⍥⚂…
  • Optimize length ⧻ deduplicate ◴
• setinv now emits a warning if the functions do not have opposite signatures
• Add the --io flag to the uiua fmt command, which formats code from stdin to stdout
• Lots of bug and crash fixes

Website

• Add a Documenting Code tutorial
• Add a Files and Streams tutorial
• Add an Experimental Features page
• Rewrite the pad code to use a <textarea> rather than a contenteditable <div>
  • This should make it work better in more browsers, especially on mobile
• You can now ctrl+click on a glyph in the editor to open its documentation
