If I'm a dev looking at engines to use, would now be the time to jump to Bevy, or is there expected to be significant changes to API and data structures moving forward still?
Things have started to stabilize, but unless you're willing to get your hands dirty and deal with regular breaking changes, I don't yet recommend staking your livelihood on it. That being said, by the end of the year I think we will be _much_ closer to our first stable release, and I expect the number of "serious projects" adopting Bevy to increase throughout the year. Now is the right time to start _evaluating_ Bevy for future projects (and experimenting with it).
