redis 7.x-2.7

This is both a bugfix and a feature release.

WARNING: path.inc replacement is experimental and does not flush correctly when aliases are updated: do not use this feature in production. New release will come soon.

The default automatic cache prefix has changed, be careful if you update, you may need to proceed to a Redis FLUSHDB command to avoid stalling entries.

If you are anot affected by a FLUSHDB then it is strongly recommended that you update to this release.

Changelog:

• Changed the default HTTP_HOST prefix to a more reliable one determined from database credentials, which makes it both more predictable and more robust; Allows Drush to fully work with Redis.
• Added a path.inc file replacement, faster than core, test and enjoy! Moreover it adds a new (default) behavior that denies all admin paths whether they are used as a source or an alias to be used as a path alais.
• Lots and lots of documentation changes thanks to many people of the community.
