If you look at other Jetpack libraries and how quickly they move from first alpha to stable, it's quite a range.
androidx.work
goes through the whole sequence on average in about 4 months;
androidx.lifecycle
takes about 10 months. And some are longer than that (lookin' at you,
androidx.security:security-crypto
). So, when
I did this analysis a couple of months ago, I estimated Compose would take 6-10 months from first alpha to stable. Note that
1.0.0
took a year to go from first alpha to stable.
I did not attempt to analyze the average time from first alpha to first beta (ignoring RCs and stable). Plus, as Tolriq suggests, Google is big on event-driven development (they like to announce milestones at events). So, a
1.1.0
beta this week for Android Dev Summit seems plausible, if perhaps a bit quick.
