Here’s what the post says TG 0.8.7 includes:
This update primarily solves installation issues and is not required otherwise.
* quickstart corrected to properly produce egg-info directories (previously, directories could be created with “-” when it should have a “_”). Note that setuptools 0.6a9 will warn you if you have a - in your egg-info directory name. Just rename the directory, and you’ll be fine.
* Installation issues that people may have had earlier are resolved in this setuptools update.
* version number set to 0.8.7 to reflect that this is considered the “stable” version of TurboGears vs. the current 0.9 code in svn.
* setuptools 0.6a9
* sqlobject 0.7.1dev_r1457 (updated to handle the setuptools change, but also includes other bugfixes)
But of course, you’ll want to be running the SVN version :-)
