Sorry for the upcoming complaint, but it did say this is where you go with "criticism". :-)
First off, I love my WordPress blog. I've been with 2.0.10 since it came out. I tried upgrading to early 2.x versions and they were too buggy for me, so I restored and stayed with 2.0.10. This week I upgraded to 2.5, which I was relieved to find is pretty decent (a few quirks, but not bad).
When I saw the notice for 2.5.1, I tried to download it and got a "file corrupted" error from the unzip utility. I redownloaded it and the 2nd copy unzipped (I posted on this). Fortunately, I went to the forum before prepping my upgrade and found tons of posts with very troubling results.
How is it possible there are so many problems, several of them being the same 5 or 10 show-stopping problems in many posts, with no word on fixes? Is it possible that, like 2.2, someone bad had access to the source code and messed with the code? Whether yes or no, why is 2.5.1 still available for download? It doesn't work. Why hasn't someone addressed this huge problem?
