I regularly push new commits to the PKSM's repository on GitHub, and the wondercard database has been updated the last time yesterday. Even though I can't release an official stable release for now, the code is open source so you can download it and compile it to get all the new contents that are still to be released officially.
Also, if you really want to donate something, there's a link in the readme on the github page, somewhere near the end.
Not everyone has the knowledge to compile, nor have the means to do it themselves. But I understand what you are saying be that as it may.
