My conclusions after reading the TSS thread carefully:
So basically for example when spring 3.0 comes out, you'll get all 3.0.1, 3.0.2, etc releases after that like before, for 3 months. Then you yourself, or some nice volunteer on the web must build the jar files from the source. Or in other words, for users of Maven you'll always find latest and greatest jars in the public repo even if it's not build and uploaded by spring guys but by a volunteer.
And, if you report a bug against an older version don't expect it to get fixed, because old releases are maintained for paying customers only. They are trying to cut costs by just supporting latest version for normal users.
I personally don't have much of a problem with this arrangement. Most people stick with ancient major releases anyway!! I try to keep up with the latest version though. But if you lag behind and use older versions and find a bug then you're in a little trouble depending on the situation: if the bug is fixed already in a later version than yours then you should build a snapshot of their svn with the fix in it, or it's not fixed and you report it and it gets a very low priority. Moral of the story: hereafter don't lag behind anymore
