# Changes

## 2.2.2 (2025-06-24)

Continuous integration:

- Switch to the GitHub Action `softprops/action-gh-release` for automatic
  pre-releases. (contributed by @muzimuzhi in expltools#82, e0dad5ad)

Documentation:

- Document the current limitations of the MikTeX distribution and using shell
  escape to execute Lua code.
  (reported by @obskyr in [witiko/markdown#566][markdown-566] and by @viocha in
  [witiko/markdown#573][markdown-573], escalated upstream by @witiko in
  [miktex/miktex#1630][miktex-1630], documented by @witiko in
  [witiko/markdown#574][markdown-574] and #32)

  These are the current limitations:
  1. The filenames of your .tex files may not contain spaces, see also
     [witiko/markdown#573][markdown-573].
  2. If `-output-directory` is provided, it may not contain spaces and it won't be
     automatically detected by MikTeX, see also [miktex/miktex#1630][miktex-1630].

## 2.2.1 (2024-12-16)

Fixes:

- Prevent unintended expansion of `\input` and similar commands in
  `\luabridge_tl_set:Nn` in LuaTeX. (witiko/markdown#530, #29)

Continuous Integration:

- Use explcheck to check expl3 code in the continuous integration.
  (witiko/markdown#535, #30)

## 2.2.0 (2024-07-03)

Development:

- Automatically determine value of `\c_luabridge_default_output_dirname_str`
  based on the current output directory.
  (witiko/markdown#457, #26, #27, reported by @hongy19)

Continuous Integration:

- Automatically test the library on both Linux and Windows.

## 2.1.0 (2024-02-14)

Development:

- Define function `\luabridge_tl_set:Nn`.

## 2.0.2 (2022-10-24)

Fixes:

- Fix tokenization in error-reporting code. (#17, #19)
- Catch compilation errors in TeX engines other than LuaTeX. (#18, #20)

Refactoring:

- Remove useless uses of `\l_tmpb_tl`. (24e116d)

## 2.0.1 (2022-08-16)

Fixes:

- Apply proper error handling when executing Lua via shell escape. (#15)

## 2.0.0 (2022-08-08)

Breaking Changes:

- Use `\sys_get_shell:nnNTF` from l3sys instead of `\immediate\write18` and
  `os.execute()`. (#13)
    - Merges `\c_luabridge_method_write_eighteen_int` and
      `\c_luabridge_method_os_execute_int` into
      `\c_luabridge_method_shell_int`.
    - Removes `\g_luabridge_standard_output_filename_str` and
      `\c_luabridge_default_standard_output_filename_str`.

Fixes:

- Execute chunks that end with `end` or a Lua comment. (#11, #14)
- Sandbox direct Lua access. (#11, #14)
- Make nested calls defined behavior. (#8, #13)

Refactoring:

- Remove needless whitespaces in Lua code.
- Replace (plain) TeX primitives with `\iow_*` l3file functions. (#1, #3,
  latex3/latex3#1105, latex3/latex3#1114. latex3/latex3#1117)
    - Many thanks to @josephwright, @u-fischer, and @FrankMittelbach at
      latex3/latex3#1114, and Hans Hagen, @hmenke, and @mojca at
      [dev-context][1] for helping to make l3file compatible with ConTeXt MkII.
