The last update of DMD resulted in longer compiler times due to one of the bugfixes. Now, 1.039 and 2.023 have been released with that particular bugfix reverted. Compile times are back to where they should be. Additionally, Walter has sped up long division significantly in both versions. And the optimizer in 2.023 now makes use of immutable and pure to do its thing. Both versions also got a handful of new bugfixes as usual.
The usual warnings for newcomers to D. The 1.x series of DMD is stable and is the version you should use for production code. The 2.x series is still likely to pull the rug out from under you, so only use it if this is an acceptable risk.
