Bug fixes
---------

### Cohesion no longer switches the site into and out of maintenance mode when rebuilding via drush 

#### What is it?

In certain circumstances, users were seeing the error "MySQL has gone away" after running 'drush cohesion:rebuild'

This was caused by a combination of MySQL configuration and/or a long running CRON or drush command process that running 'cohesion:rebuild' command contributed too.

More information: https://www.drupal.org/node/259580

It was decided that developers working with Cohesion should be responsible for bringing the site into and out of maintenance mode if required and that Cohesion should not enforce this.    

#### What impact will there be?

When running 'drush cohesion:rebuild' note that your site will no longer go into and out of maintenance mode when running this command. 

#### What actions do I need to take?

If you require this functionality, you will need to implement it yourself inside your build scripts.  
More information: https://www.drupal.org/docs/user\_guide/en/extend-maintenance.html

#### Are there any risks I should be aware of?

See above.

### Fixed an issue where icon and font files were not showing 

#### What is it?

In certain configurations of Acquia Cloud and Acquia Cloud Site Factory hosting, it was possible that font and icon files were not being referenced on the front end correctly. This resulted in missing font and icons on the front end of the website. 

#### What impact will there be?

Users that reported this issue will see it has been resolved.

#### What actions do I need to take?

A Cohesion import and rebuild is required after upgrading to the latest version of the module.

#### Are there any risks I should be aware of?

No

### Initial page rendering performance improvements 

#### What is it?

We've improved the time to build Cohesion layout canvas enabled pages for the first paint (before the cache has been built).  

#### What impact will there be?

Users making changes to Cohesion powered content entities will see their page rendering more quickly.

#### What actions do I need to take?

No actions are required.

#### Are there any risks I should be aware of?

No
