WP Super Cache 0.9.9.2 has just been released! This version works with WordPress 3.0 and adds a number of new features and bug fixes:
- Cache Preloading will cache every post on your site.
- A cache tester that will check if your homepage is cached.
- Much better support for mobile plugins.
- Mod rewrite rules can now be updated from within the admin page.
- Lots and lots of bugs fixed. See the changelog for more details.
Preloading creates lots of files on your server so if you have many thousands of posts please be aware of this. Filesystem limitations may cause problems if you use a flat permalink structure. For example, ext2 or ext3 only allows 32,000 directories in a directory. If you have more than that number of posts you may run into problems.
The plugin does not preload category or tag pages but because your single posts will be cached you’ll find the load on your server will be reduced. Uncached pages will be served more quickly and your visitors will have a quicker and better experience on your site.
You may also see an increase in site traffic if your server was previously underpowered!
Update! I just released 0.9.9.3 to address the (mostly minor) bugs that were reported overnight. If you don’t notice anything wrong there’s no need to upgrade.
