* Added Android SDK version to the SystemInfo trace packet.
* Changed compiler flags. Assume recent x64 CPUs (-msse4.2 -mavx -mpopcnt).

* The java heap profiler now rescans all the processes every time for
continous_dump_config. The scan_pids_only_on_start can be used to restore
the old behavior.

+ * Added support for building on ARM Macs.
+ * Added support for the rss_stat_throttled event on Android via
+ FtraceConfig.throttle_rss_stat. In newer Android kernels the base rss_stat
+ event is now unthrottled. rss_stat used to be throttled by a downstream
+ kernel change, unnecessary after https://lkml.org/lkml/2021/10/25/1411 .
+ atrace.rc configures throttling from userspace at boot.
+ * Fixed a bug that caused IPCs to stall traced and hit the watchdog if in
+ the middle of a suspend/resume. Switched from SND_TIMEO to poll(POLLOUT).
+ * Added "linux.sysfs_power" data source to poll /sys/class/power_supply/
+ and report periodically battery charge and drain rate if supported.
Trace Processor:
+ * Speeded up proto trace ingestion by 2x (~20 MB/s -> ~40 MB/s).
* Changed LIKE comparisions to be case-senstive. This may break existing
queries but was a necessary from a performance perspective.
+ Going forward, GLOB must be used, instead of LIKE, for checked in metrics
+ to avoid unnecessary slowdowns.
* Changed compiler flags, assume recent x64 CPUs (see above).
* Changed how displayTimeUnit is handled in JSON traces to match catapult.
+ * Added websocket endpoint to RPC interface to reduce query latency.
+ * Added support for hot-reloading metrics (see //docs/analysis/metrics.md).
UI:
- *
+ * Added ability to save/restore record config. Remember last used config.
+ * Fixed bug causing the recording page to hold onto the USB interface making
+ adb unusable after a recording session.
SDK:
* Added UpdateDataSource() descriptor IPC endpoint to allow updates of the
data source capabilities (e.g., category list for track event).
