I have installed WordPress 2.0.7, which was just released a few hours ago.
This time, I did not merely upgrade the previous installation; I uploaded a fresh copy of all files so I could do some tinkering without affecting what little live content I have more than necessary. I moved the content from /wordpress to /blog, but I encountered some difficulties of which troubleshooting is presently less compelling than preparing or purchasing some sustenance—updating the permalinks did not seem to update part of the database that my custom index-generator uses and I was not happy with the plain 404 Not Found messages that appeared in place of the previous content pages—so I moved it back for now.
Despite having a content management platform of my own in PageDrive, I like WordPress well enough that I have been tempted to spend some time customizing it—making my custom installation preferences work better, of course, but hopefully also improving some of the things I do not like about WordPress—and release my customizations under a compatible license.
As always, please let me know if you encounter any problems or oddities.
