v1.1.9 - 2024-12-13

Release notes

Added

• aiken: Generate a default 'placeholder.ak' validator when using aiken new. See #1061 @waalge
• aiken-lang: New builtins unconstr_fields and unconstr_index. @MicroProofs
• aiken-lang: Added builtins from Chang2 hardfork (except for writeBits). @MicroProofs, @KtorZ
  • Bitwise operations
  • Ripemd-160 hashing
• aiken-projects: The generated documentation may now include maths typesetting rendered using KaTex. See #1070 @adrian052.

  • (Linux & MacOS only) Both inline (delimited by single $ symbols) and blocks (delimited by doubled $$ symbols) are now parsed and rendered as SVG upon generating documentation. For example:

    $$
    g^{z} = g^{r +c \cdot x} = g^{r} g^{x \cdot c} = g^{r} (g^{x})^{c} = g^{r} u^{c}
    $$
    

    will display:

    $$ g^{z} = g^{r + c \cdot x} = g^{r} g^{x \cdot c} = g^{r} (g^{x})^{c} = g^{r} u^{c} $$

• uplc: New builtins from Chang2 hardfork added to the VM along with costing. @hadelive, @MicroProofs

Changed

• aiken: Fix aiken blueprint policy computing hashes as PlutusV1, instead of relying on the plutus version from the Blueprint. @KtorZ
• uplc: Parse tild in identifiers for UPLC nodes. @SupernaviX
• examples: Update "Hello, World!" source code tutorial to match website, now using MeshJS. @jinglescode
• examples: Update "Gift Card" source code tutorial to match website, now using Lucid-Evolution and Weld. @rvcas
• aiken-lang: Fixed a code gen crash when using records in when is expressions. @MicroProofs
