1.0.4 - 2026-04-07
Maintenance under BeAPI: clearer docs, automated code-style checks in CI, and small hardening in PHP.
For the full patch, see commit fc1a475.
- Automated checks with PHPCS and the WordPress Coding Standards on push and pull request (GitHub Actions).
- Local commands
composer cs(check) andcomposer cbf(auto-fix) for the same rules. - This changelog file, linked from the README.
- A
.gitignoreso Composer’svendorfolder (and lockfile, if you choose) stay out of version control by default.
- README rewritten: what the loader does, how to install with Composer or by hand, and how to ship your own MU plugin.
composer.jsonbrought in line with the 1.0.4 release (license, dependencies, BeAPI as maintainer).- Plugin headers updated for BeAPI (#4).
mu-loader.phpadjusted to match coding standards and current usage of WordPress APIs (including how subdirectory plugins are listed in the admin).
- If
mu-loader.phpis missing, the admin notice now escapes the displayed path so the message is safe to output.
1.0.3 - 2016-08-26
- Install and upgrades: the loader does nothing while WordPress is installing or updating (
WP_INSTALLING), so it does not get in the way (#3). - Multisite: cache flushing works more reliably for network administrators.
- Discovery: plugin matching is no longer case-insensitive, so behaviour is easier to predict.
- Subdirectory plugins are required without waiting for all MU plugins to finish loading first.
- Author and package metadata updates, plus other small improvements from contributors.
1.0.2 - 2015-01-21
- Fresh installs: no confusing errors when the database tables are not there yet (commit e1fcd9b; change originally came from the upstream project via rexblack).
1.0.1 - 2014-12-10
- README gains more detail on installation and usage.
1.0 - 2014-02-06
- First release: load must-use plugins that live in subfolders of
wp-content/mu-plugins/, not only single PHP files at the root.
