1.9.0

• changes in HTML debug comment: instead of the former, single comment, now 2 comments are added. The first is added when the cache entry is generated; the second only appears if the page was served from the cached entry. Please note that this last bit will – should – change with every single refresh.
• backend code is now split into separate files
• more debug code

1.8.3

• added additional debug condition of WP_FFPC__DEBUG_MODE constant to be true

1.8.1

2015-04-29

• fixing the wrong release of 1.8.0

1.8.0

2015-04-29

What’s new:

• backend keys are now sha1 hashes instead of full url; this is to prevent too long key error with memcached

Under the hood:
* wp-common is removed; no more git submodules
* logging method changed

1.7.9

2015-02-02

What’s new:

• detailed log messages for other log message clarification
• added auto-upgrade for advanced-cache.php on plugin upgrade

1.7.8

2015-01-30

What’s new:

• merged pull request for wp-ffpc-purge

1.7.7

2015-01-14

What’s fixed:

• fixed alert backwards compatibility for PHP < 5.3

1.7.6

2015-01-09

What’s fixed:

• anonymus function call only for PHP 5.3

1.7.5

2014-12-29

What’s fixed:

• wp-ffpc was not actually alerting when it had issues; this should be fixed now

This was a really bad bug and it could have cause a lot of issues since the plugin was probably not working in some cases when the alerts went unnoticed. Due to WordPress restrictions on admin_notices hook I had to use PHP features only present since 5.3. Please keep this in mind.

1.7.4

2014-12-17

What’s changed:

• localhost cache forced exclude removed; instead please use define('WP_CACHE', $_SERVER['REMOTE_ADDR'] !== '127.0.0.1'); instead as pointed out by plescheff if required
• compatibility tested up to WordPress 4.1

1.7.3

2014-12-17

1.7.0

2014-09-19

What’s new:

What’s changed:

• dropped Xcache support: the reasons behind this is the outstandingly terrible documentation of Xcache
• dropped persistent memcache mode: no one was using it and even if the were only caused trouble
• removed ‘/wp-‘ hardcoded cache exception; this is now the default in the regex exceptions field as ^/wp-; please add this manually in case you’ve already been using the regex field

What’s new:

• additional cookie patterns to exclude visitors from cache, contribution from Harold Kyle
• syslog dropped; using “regular” PHP log instead
• pre-cache from wp-cron
• changeable key scheme ( was fixed previously ); possibility to add user-specific cache if PHPESSID cookie is present

What’s fixed:

• logged in cookie check fixed ( was not checking all WordPress cookies )
• global error messages to show if settings are not saved

Dropped functionalities

• there’s no info log on/off anymore, it’s triggered when WP_DEBUG is active
• sync protocols has been removed for two reasons: this has to be done by other systems and causes issues in special cases

For Devs

• the abstract class have been moved into a separate Github repository, wp-common. Because PHP is not capable of replacing/redefining classes, there’s a versioning with the abstract and the utilities class, please be aware of this.

What’s fixed:
