## Highlights

Major changes since 6.0.0:

* `Zope`:
  * Set the published default Content-Type header to text/plain if none has been set explicitly to prevent a cross-site scripting attack.  Also remove the old behavior of constructing an HTML page for published methods returning a two-item tuple.  This fix was already included in Plone 6.0.0.1 and 6.0.0.2.
  * Various other packages have fixes for this to avoid regressions.
* `plone.restapi`:
  * Internationalization of `@users` endpoint error messages.
  * Add pt_BR and fr translations.
* `plone.base`: Add missing TinyMCE plugin `autolink` to selectable plugins.
* `Products.CMFPlone`: When autologin after password reset is enabled (this is the default), use the same adapters as during normal login. Specifically: the `IInitialLogin` and `IRedirectAfterLogin` adapters.
* `plone.recipe.zope2instance`: Add new option `asyncore_use_poll` to waitress config file. You might need this when you have fast-listen enabled, which is the default, and run into [100% cpu usage on all Plone instances](https://github.com/plone/plone.recipe.zope2instance/issues/188).  But investigation on that problem is ongoing.
* More Zope community packages have gotten official, tested Python 3.11 support.


## Volto frontend

The default frontend for Plone 6 is Volto. Latest release is [16.9.0](https://www.npmjs.com/package/@plone/volto/v/16.9.0).  See the [changelog](https://github.com/plone/volto/blob/16.9.0/CHANGELOG.md).
Note that this is a JavaScript frontend that you need to run in a separate process with NodeJS.
The Classic UI is still available when you only run the Python process.
