+# docstub v0.6.0
+
+We're happy to announce the release of docstub v0.6.0 on 2025-11-04!
+
+## Enhancement
+
+- Add the new experimental `--workers` option to `docstub run` to **generate stub files in parallel**. This can reduce runtime significantly for projects with many files. For now, multiprocessing has to be explicitly enabled by requesting a number of workers ([#110](https://github.com/scientific-python/docstub/pull/110)).
+- **Highlight help messages** (invoked with `-h` or `--help`) of the command line interface with colors and reformat. This should improve the readability ([#109](https://github.com/scientific-python/docstub/pull/109)).
+- Don't color output if the environment variable `NO_COLOR=1` is set ([#109](https://github.com/scientific-python/docstub/pull/109)).
+- Support using types from the standard library module `types` directly without requiring configuration or imports for them ([#106](https://github.com/scientific-python/docstub/pull/106)).
+- Provide file and line context in warnings that are emitted while parsing doctypes ([#108](https://github.com/scientific-python/docstub/pull/108)).
+- Add the short command line option `-g` as an alternative to `docstub run --group-errors` ([#109](https://github.com/scientific-python/docstub/pull/109)).
+- Hide additional debug information behind "verbosity 3" (`-vvv`). This makes the option `-vv` a bit more usable.  Also use a  more generally visible ANSI color for debug  information (bright_black) ([#104](https://github.com/scientific-python/docstub/pull/104)).
+
+## Performance
+
+- Speed-up how fast docstub's command line displays help text with  the `-h` or `--help` option ([#112](https://github.com/scientific-python/docstub/pull/112)).
+
+## Bug Fixes
+
+- Ensure that warnings are raised for partially documented signatures. Previously, no warning was raised for untyped parameters when at least one parameter was annotated ([#107](https://github.com/scientific-python/docstub/pull/107)).
+- Ensure that docstub still returns a non-zero exit code when it is run with output completely disabled (`-qq`). The same applies when running docstub with  `--quiet --fail-on-warnings` ([#110](https://github.com/scientific-python/docstub/pull/110)).
+- Ensure that warnings are raised for undocumented parameters and attributes. Previously, no warning was raised for parameters and attributes when at least that were mentioned in a docstring, but didn't have a doctype ([#111](https://github.com/scientific-python/docstub/pull/111)).
