Only four days from the release of PHP 5.2.7, the new PHP 5.2.8 has been released due to regression found on 5.2.7 which affected magic_quotes_gpc setting. This issue can be easily resolved by changing "filter.default_flags=0" in php.ini, but this is not done at installation time, so a new release is the best solution for end users who SHOULD NOT be bothered by this kind of operation when they wanted to install PHP on their computer.
It's really a shame though. Spending seven months of development time and when it should be a *good* release, the previous version got a serious flaw for something that will be removed in PHP 6. I think the QA team should have aware of this issue when they test the build, but unfortunately, they missed it. It's a good lesson for PHP developers and hopefully the next release will be better.
