2026-07-25

On behalf of the Rakudo development team, we announce the July 2026 release of Rakudo #195. Rakudo is an implementation of the Raku1 language.

The source tarball for this release is available from https://rakudo.org/files/rakudo. Precompiled archives will be available shortly.

New in 2026.07:

  • Improvements:
    • Make an unrecognized <| > regex boundary a no-op before 6.e and an error after
    • Bump mimalloc to v2.4.1
    • Explicitly mention the existence of the gdb python plugin

  • Fixes:

    • Make Blob stringification agree across every route
    • Render a parameter's declarator doc once under --doc
    • Compile the proxy readers with the Raku HLL
    • Smartmatch a Junction topic over its eigenstates
    • Smartmatch against a concrete Match matcher returns it as-is
    • Negated smartmatch against a Regex binds the caller's $/
    • Map a container-held foreign value when binding a value parameter
    • Give the experimental macros flag a load-independent value
    • NativeCall: enforce definiteness constraints on native signatures

  • Additions: Add Date/Datetime.yyyy-mm / mm-dd methods

  • RakuAST:

    • A lot of work on performance optimizations, and feature parity with the legacy compiler for ecosystem modules.

  • Internal:

    • Handle the runtime Failure in the constant-folding warn test
    • Remove dead code from Perl6::ModuleLoader

This release implements 6.c and 6.d versions of the Raku specification. 6.c version of the language is available if you use the use v6.c version pragma, otherwise 6.d is the default.

Upcoming releases in 2026 will include new functionality that is not part of 6.c or 6.d specifications, available with a lexically scoped pragma. Our goal is to ensure that anything that is tested as part of 6.c and 6.d specifications will continue to work unchanged. There may be incremental spec releases this year as well.
