Every time PM gets an update, the gct has to be decoded, rewritten and tested, files have to be replaced and relocated, costumes and features have to be re-added, and other things need to be done to prevent crashes. This takes a lot of time. The update to BrawlEx is already done. If you go to the kcmm thread, you can download v2 there. BrawlEx can be confusing and time consuming at times, so don't worry. Also, if you download a BrawlEx pack and want to add characters to it, you have to use files from the same version in the pack, which you can also download from the thread.
