Doesn't really fix much does it? Considering the amount of stuff that is broken.
We really need a sticky that explains why you're not going to see many fixes in release maintenance branches of code.
Simplistically, Frontier have two concurrent threads of development. The first is commonly known as the trunk, and is what developers working toward the next major release (in this case, 2.1) will be working on. It's likely to be highly fluid, in that it will be changing rapidly as new features are added and bugs fixed. The second thread is the release maintenance branch -- a branch being a snapshot of the trunk taken at a particular point in time, which may then diverge -- and that's what Frontier have pushed out to us today.
If a bug is fixed on the trunk, it doesn't automatically get copied across to the release maintenance branch. Similarly, if a bug is fixed on the release maintenance branch, it doesn't automatically get copied across to the trunk. This presents a number of configuration dilemmas for the developer: do they fix on the trunk or on the branch? What's the effort required to port that fix across? How important is it that the fix is made? Generally speaking, the cost of porting a fix increases in a non-proportional manner as the trunk and branch diverge. If the underlying code has been reworked on the trunk, the bug may no longer be present, or the fix may differ between trunk and branch; in the former case, the question is whether it's worth the effort of fixing in the branch, and in the latter case, it's whether it's worth the effort to implement the fix twice. Generally speaking this means that minor issues tend to get made on trunk only, and showstoppers or seriously detrimental ones tend to be implemented in both.
As I said, that's the simplistic explanation. In reality there'll be far more than just the two threads of development, which makes it all the more complex to manage. But the bottom line is that release 2.1 will fix many of the outstanding issues, there'll be pages and pages of bugfixes, and Frontier will introduce a whole raft of new bugs because that's just the way these things work.
