Changelog

0.11.0 - July 4, 2025

Breaking change: Fixed multiple merge duplication bug where running merge operations multiple times would create duplicate site entries in the master navigation.
Behavior change: When the same site is merged multiple times, existing entries are now replaced (not duplicated) to allow for site updates.
Documentation pipeline: Changed documentation publishing to manual trigger only.
Added comprehensive test suite for multiple merge scenarios including mixed existing/new sites and interaction with the unify_sites feature.
Formatting all code with black formatter.

Permanent fix for #20: replaced dir_util.copy_tree with shutil.copytree to use a built-in and maintained API in the directory merge functionality.
Added a test to verify the scenario of deleting paths and merging them again when using mkdocs-merge as a module.

Fixed bug of dir_util.copy_tree caused by setuptools moving to 70.2.0 (fixes #20).
Updated dependency on deprecated distutils package to use setuptools version.
Updated project to use pyproject.toml instead of setup.py (package version now has to be manually kept in sync).

Added support for section index pages feature from MkDocs Material (thanks to @Acerinth).

Breaking change: added support for added support for MkDocs 1.0 and dropped support for earlier versions.

Fixed the merge process ignoring the docs folder in the mkdocs.yml of the sites to merge.
Removed support for Python 3.3 due to pip removing support for it.

Separate CLI functionality from the Merge logic for a more module friendly package.
