As the new version (2.4.0) is rapidly coming closer to its release I wanted to inform you of a few important things before you decide to upgrade. I'm posting this now, so that visitors of the forum have already seen this information (some people just don't read readme files ;)).
As always you should be able to apply the upgrade to an already running pool. The data won't be affected. I tested this on some databases with test data, but to be perfectly save, please backup your database before you upgrade. It could go wrong. Maybe I made a mistake, or maybe the upgrade from WordPress is interrupted in the middle of the process.
If you made changes to the plugin's files (code, images, css, js or language files) also make a backup of your files. Those changes will be overwritten on an upgrade. Code changes will have to be done again and possibly rewritten to fit my new code.
If you used actions or filters (hooks) to extend the functionality of the plugin, please verify that they are still working and doing what you want. I did some rewriting of some parts of the plugin that as a whole make the plugin better (in my opinion ;)), but may break your changes.
And finally: I made some changes to the database that require a recalculation of the ranking; I can't automate this in the upgrade. So please do a full calculation after the upgrade.
That's all for now. If you have any questions, please don't hesitate to ask. Just reply to this post.
When will version 2.4.0 be released? I'm aiming for May 1.
