I'm slightly skeptical of that data (although a quick look doesn't make it clear there's anything wrong with it, if there actually is) - but my understanding has always been that the uptake of new Firefox versions is slower than we'd like, but generally successful within the 6 week cycle. By contrast, if I look at 10% of all desktop Firefoxes that submitted a sync ping in the last 7 days I get: 49 - 1, 0.00 50 - 26527, 0.34 51 - 27602, 0.35 52 - 419814, 5.31 53 - 56468, 0.71 54 - 257171, 3.26 55 - 7002788, 88.63 56 - 83928, 1.06 57 - 26413, 0.33 so in that 10% sample, there was exactly 1 version 49. Looking at 52 (current ESR) and up gives ~99.3% of all pings. https://gist.github.com/mhammond/46906eb3de269f3969e2fffc6dd801eb FWIW, going back 28 days (still a 10% sample) shows the same basic pattern, although obviously 54 is higher due to it being the current release for some of that period. 49 - 5, 0.00 50 - 109896, 0.36 51 - 117934, 0.39 52 - 1829602, 6.03 53 - 231241, 0.76 54 - 6847774, 22.58 55 - 20751445, 68.42 56 - 343482, 1.13 57 - 98950, 0.33 (this is the same gist as above, but ndays=28 instead of ndays=7) Mark _______________________________________________ Sync-dev mailing list Sync-dev@mozilla.org https://mail.mozilla.org/listinfo/sync-dev
