The first 1.17 pre-release is here!
\nFrom now on, you should mostly see bugs being fixed. In addition to that, pre-releases doesn't follow the regular snapshot cadence of releasing on Wednesdays, so keep an eye out!
\nAddtionally, based on feedback from the community, we have decided to include candles in part 1 of Caves & Cliffs again. Candles will become available in Bedrock shortly after the release of part 1.

The exact metrics, output format, and names are susceptible to change between versions. Our plan is to continue iterating on which metrics to capture.
\nPressing F3+L while in the game will start a recording for 10 seconds capturing metrics such as tick durations, used heap sizes and other more detailed stats.
\nPressing F3+L before the 10-second limit will end the recording early.
\nThis shortcut is always available to clients, even on multi-player servers where it will record client-side performance.
\nperf start will start a recording for 10 seconds capturing metrics such as tick durations, used heap sizes and other more detailed stats.
perf stop before the 10-second limit will end the recording early.
