The Evolution of Evolution: Steady Progress - page 4
Obtaining EvolutionThe release schedule for Evolution is about to step up, which means users will be able to watch the project progress more promptly. Though no firm dates have been set, within the next few weeks more frequent builds will become available. The process of trying Evolution out will become much easier as many of the libraries it relies on begin to firm up and slow their development cycles, becoming more readily available as distribution-native binary packages.
Depending on what kind of mail user you are, the current binary release may be enough to use daily. If you're waiting for something to replace your tried-and-true mail setup and rely heavily on fine-tuned filtering, it's probably best to wait.
