 ### explcheck v0.16.0

 #### Development

 This version of explcheck has implemented the following new features:

 - Support specifying cut-off dates for deprecations from the file
   `l3obsolete.txt` and prefixes from the file `l3prefixes.csv`.
   (suggested by @YDX-2147483647 in #147 and #149, added in #150)

   For example, here is how your config file `.explcheckrc` might look if you
   would like to only take into account the deprecations and prefixes from
   TeX Live 2024 and earlier:

   ``` toml
   [defaults]
   l3obsolete_max_deprecated_date = "2024-03-30"
   l3prefixes_max_first_registered_date = "2024-11-18"
   ```

   You may get these dates by running the script `generate-explcheck-latex3.lua`
   with files `l3obsolete.txt` and `l3prefixes.csv` from TeX Live 2024 placed in
   the current working directory or other locations indexed by the KPathSea
   library. Here is the output of the script:

   ```
   LPEG parsers and other information extracted from LaTeX3 data files.
   Generated on 2025-11-06 from the following files:
   - "l3obsolete.txt" with the latest obsolete entry from 2024-03-30
   - "l3prefixes.csv" with the latest registered prefix from 2024-11-18
   ```

   You may also just use the dates of the last update to TeX Live 2024
   (2025-03-09) for both options, see https://tug.org/historic, directory
   `systems/texlive/2024/tlnet-final`.

 #### Fixes

 This version of explcheck has fixed the following bugs:

 - Fix an attempt to index a nil value in function `count_segments()` from the
   file `explcheck-evaluation.lua`. (#150)

   This bug would surface when printing results for files whose processing
   stopped before the syntactic analysis step.

 #### Continuous integration

 This version of explcheck has made the following changes to our continuous
 integration:

 - Use historic files "l3obsolete.txt" and "l3prefixes.csv" in CI. (#150)

 - Include example files from the `doc` subtree in regression tests. (#150)

   This has reduced code coverage from ca 24% to 21% of all expl3 tokens on
   TeX Live 2024 and from ca 22% to 20% on current TeX Live 2025 (2025-11-06).

 - Check if the configuration is minimal even for expl3 files without any
   issues. (#150)

   This is necessary to prevent incorrect recommendations to remove unnecessary
   default settings from the file `.explcheckrc` in the script
   `prune-explcheck-config.lua`.

 - Bump actions/checkout from 5 to 6. (contributed by @dependabot in #151)
