Language

• Breaking Change - repeat ⍥ and do ⍢ with net-negative signatures now preserve lower stack values between iterations
• Breaking Change - atangent ∠ now interacts with under ⍜ similarly to couple ⊟ and complex ℂ
• Add subscripted on ⟜, by ⊸, with ⤙, and off ⤚
  • These preserve N arguments rather than just the first or last
• Add data definition methods
• Stabilize most of data definitions
  • A new section has been added to the tutorial
  • Things not stabilized:
    • Data functions
    • Methods
    • Field validators
• Stabilize subscripted random ⚂
• Signature comments can now use a $ rather than a ? to automatically label arguments and outputs
• Change backward ˜'s glyph back. 𝄈 will continue to work and will be formatted as ˜.
  • This glyph has much better font support
• Stabilize backward ˜
• Add anti ⌝ keep ▽ for parity with select ⊏
• Add subscripts for bits ⋯ to force the number of bits
• Allow tuples ⧅ to take infinity ∞ as a first argument
• Deprecate over ,
  • It is part of a stack manipulation paradigm that Uiua is slowly moving away from
  • with ⤙ and below ◡ replace the vast majority of over ,'s use cases
  • You can find a short blog post about this change here
• Stabilize sided subscripts for both ∩ and bracket ⊓
• Add un ° with ⤙ and un ° off ⤚
• Add sided subscripts for reach 𝄐
• Add the # External! semantic comment to mark functions that are provided via Rust code
  • These functions don't require a Uiua implementation and will show up in the LSP
  • Calling an # External! function that hasn't been bound will throw an error
• Add experimental self ˙ modifier
• Add experimental subscripts to negate ¯
  • This will multiply × a number by the Nth root of unity
• Remove &clget alias for &clip
• Remove previously deprecated &httpsw

Interpreter

• Add UIUA_MAX_MB environment variable to set the maximum size of an array in megabytes
  • This allows catching memory errors on different systems
• Optimize absolute value ⌵complex ℂ to not create intermediate complex ℂ array
