 * Fix: load the backwards-compatibility aliases and the `msls_*()` functions when the plugin file is included instead of on `plugins_loaded`, and keep the settings page slug handed to `msls_admin_register` at its pre-3.0 value. Add-ons such as MslsMenu load before the plugin and check `class_exists( 'lloc\Msls\MslsOptions' )` before registering anything, which silently disabled them — no add-on settings section, and no switcher in the nav menu.
 * Fix: check authorization on the destination post during content import, and correct the ContentImporter permission and post type checks.

+
+* New: Quick Create - create the translated post straight from the editor metabox, or pick a source post on the new `Add from Translation` submenu (single and bulk). Backed by a REST endpoint and switchable in the settings.
+* New: `msls_quick_create_capability` lets integrations override the Quick Create permission checks. Additional filters cover the post data, the inserted post, the REST response, the untranslated-posts list and the mapped taxonomy terms.
+* New: filter hooks for the AJAX suggest results of the post and term metaboxes.
+* New: a developer reference in `docs/` - public API, every hook, integration snippets and the Playwright setup.
+* Changed: the `lloc\Msls\` namespace is split into per-concern sub-namespaces. Every pre-3.0 class name (`MslsOptions`, `MslsLink`, `MslsOutput`, ...) keeps working through a backwards-compatibility alias, so add-ons and custom code do not need changes.
+* Changed: the public helper functions moved to `includes/api.php`, and the `$attr` argument of `msls_get_switcher()` is now optional.
+* Fixed: add-ons such as MslsMenu and MslsSelect could be silently disabled because the plugin registered its classes too late. Aliases and API functions are now available the moment the plugin file is loaded.
+* Fixed: authorization is checked on the destination post during content import, and the ContentImporter permission and post type checks were corrected.
+* Fixed: no `home_url()` fallback for taxonomy and query archives anymore.
+* Fixed: broken links on the page for the latest posts.
+* Fixed: several issues in the blog collection.
+* Internal: strict typing throughout, PHPStan level 8 clean, `ABSPATH` guards, Plugin Check and PHPCS findings addressed, a wp-env based local multisite and a Playwright end-to-end suite.
+
+= 2.10.1 =
+
+* Fixed: deprecated function warning pointed to a non-existent function.
+* Documentation: README.md code snippets reflect the new function names.
+
+= 2.10.0 =
+
+* New: prefixed public helper functions (`msls_get_*`, `msls_the_switcher`) with deprecation shims for the legacy names.
+* New: action hook names are exposed as constants for safer programmatic use.
+* Accessibility: `aria-current="page"` on the active language link.
+* Fixed: path-related issue affecting asset/loader resolution.
+
+The full history is kept in the separate [Changelog](https://github.com/lloc/Multisite-Language-Switcher/blob/master/Changelog.md).
+
+== Upgrade Notice ==
+
+= 3.0.0 =
+
+Major release. The class structure moved into sub-namespaces, but every pre-3.0 class name
+still resolves through a compatibility alias, so add-ons, themes and snippets keep working.
+Requirements are unchanged (PHP 7.4, WordPress 6.1). Clear your opcode cache after updating.
