I disagree with Rockphed's assessment and support Random_Dragon's sentiment:
0.43.05: 64 bits. 2/3 bugs fixed.
0.43.04: New compiler (not mentioned). 6/12 bugs fixed. This includes introduction of armor damage and new combat mechanics for forces which are listed as "tweaks".
0.43.03: 3/20 bugs fixed.
0.43.02: 5/2 bugs fixed.
0.43.01: 12 new things. 1/7 bugs fixed.
0.42.06: 6 new things. 5/6 bugs fixed.
0.42.05: 3 new things. 7/12 bugs fixed. This includes zombie nerfing/rework.
0.42.04: 2 new things. 7/9 bugs fixed.
0.42.03: 15/15 bugs fixed.
0.42.02: 6/3 bugs fixed.
This sums up to 6 "new stuff" releases out of the last 10 (one is a number bump prompted by the fact that the amount of new stuff bumped the number, which I don't see as a reason to exclude it from the count. It's still in the middle of the latest arc). I stopped there because the "too little bug fixing" complaint is mainly related to the latest arc, which started with 0.42.01. The main point is that the last two releases were mainly new stuff that wasn't noted in the release notes, and fairly thin in fixing bugs introduced 0.42.01 onward.
I realize we're in disagreement over what an appropriate amount of bug fixing vs progress is, and hope we can agree on disagreeing rather than starting a new flame war, though.
