Log message:
re2c: update to 4.5.1.

4.5.1 (2026-03-27)
~~~~~~~~~~~~~~~~~~

- Added missing include files to the distribution
  (`#573 <https://github.com/skvadrik/re2c/issues/573>`_).

- Updated the documentation to mention the new include files.

Log message:
re2c: updated to 4.5

4.5 (2026-03-23)

- Migrated include files to Unicode 17.0.0 standard.

- Added Unicode include files:

  + `include/unicode_blocks.re \ 
<https://github.com/skvadrik/re2c/blob/master/include/unicode_blocks.re>`_
  + `include/unicode_properties.re \ 
<https://github.com/skvadrik/re2c/blob/master/include/unicode_properties.re>`_

- Implemented Unicode case mapping for case-insensitive string literals

- Fixed `571 <https://github.com/skvadrik/re2c/issues/571>`_
  (segmentation fault on erroneous input during determinization).

- Updated paper `A closer look at TDFA <https://arxiv.org/abs/2206.01398>`_
  (applied corrections by Lisa Felidae).

Log message:
re2c: update to 4.4.

4.4 (2025-12-20)
~~~~~~~~~~~~~~~~

- Added generalized end-of-input symbol ``$``
  (`#525 <https://github.com/skvadrik/re2c/issues/525>`_).
  This change may break old code with conflicitng end-of-input rules,
  as they now have position-based precedence. The broken cases were
  reported with ``-Wdeprecated-eof-rule`` since version 4.3.

Log message:
re2c: updated to 4.3.1

4.3.1 (2025-12-01)

- Fixed bugs:
    (allow conditions that have no rules except for default rule)
    (use unsigned character type in C/C++ examples)
    (fix broken end of input rule $ with captures)

Log message:
re2c: updated to 4.3

4.3

Added warning -Wdeprecated-eof-rule, this will be turned to error in the future
Improved re2c performance

Log message:
*: use CMAKE_GENERATORS_INCOMPATIBLE

Log message:
re2c: updated to 4.2

4.2 (2025-04-23)

- Added Swift backend

- Added options:

  + ``--lang swift``
  + ``--computed-gotos-relative``

- Added configurations:

  + ``re2c:cgoto:relative``, ``re2c:computed-gotos:relative``
  + ``re2c:yyfn:throw``

- Added syntax file code templates:

  + ``code:cgoto``
  + ``code:cgoto_data``
  + ``code:yytarget_filter``
  + ``code:type_yyctable``

- Added syntax file conditionals:

  + ``.cgoto.relative``
  + ``.yyfn.throw``

- Added some C++ benchmarks without submatch extraction.

Log message:
re2c: updated to 4.1

4.1 (2025-02-16)

Added new syntax for actions
Added entry, pre-rule and post-rule actions
!entry action binds code at the start of the current finite state machine
!pre_rule action prepernds code to semantic actions of all rules in the current \ 
block or condiiton.
!post_rule action appernds code to semantic actions of all rules in the current \ 
block or condiiton.
Added syntax file option special_escapes that describes allowed escape sequences

Fixed bugs:

(allow using lookahead operator with captures).
(integer overflow caused a very long loop when generating tag names).
(segfault on !use directive in a block with conditions).
(regression with bit-vector optimization).
(failure to recognize escaped double quotes in character literals).
OCaml backend now uses unsafe_get instead of get as the default YYPEEK \ 
implementation.
Zig backend now uses const for yych declaration in --recursive-functions mode.

Benchmarks (C/C++):

Reimplemented benchmarks using google-benchmark library.
Added simple variants without buffer refill.
Removed Kleenex benchmarks.
Removed deprecated TDFA(0) and StaDFA algorithms.
Updated benchmark results.

Build system:

Migrated to Bazel 8 using bzlmod.
