I can understand the frustration some of you are having with the changes to the new version and I sincerely apologize for that. Releasing something after 2 years and ensuring that nobody will have any issues is not easy, which is why the two-year delay in updates is not something I want to let happen again.
I'm actively fixing bugs and taking feedback for new features. If you want to report a bug or submit a feature request, please do so on GitHub.
@paontheweb If you're auto-updating plugins on hundreds of WordPress sites, you should really be testing each new version of the plugin prior to the update. (This applies to all WordPress plugins, not just Quick Cache.) The potential for something to go wrong with a plugin update is always there and auto-updating plugins on hundreds of WordPress sites warrants extra care and responsibility.
@snakesmaster @paontheweb If you're unhappy with the latest version of the plugin, you can always download the last release of the old version (v111203, released on December 3rd, 2011).
@Army Thank you for the support! :)
