v44.0 - 2024-04-10:
Trace Processor:
* New modules added to standard library: `frames.timeline`,
`frame.per_frame_metrics`, `sched.time_in_state`.
UI:
* Per-cpu scheduling tracks now distinguish real-time priority threads with
a hatched pattern and name prefix. Based on priority during switch-in.
* Added ftrace event cropping for traces recorded by perfetto v44+.
Events are ignored if they precede the earliest timestamp covered by all
per-cpu data streams. This should significantly improve the presentation
of RING_BUFFER traces, removing artifacts such as never-ending slices
starting at the beginning of the trace.
* Significantly improved trace load times.
* Improved counter track view modes, including log scale, expanded view, and
the ability for plugin authors to link scales of several counter tracks
together.
* Add dominated size and objects to Java heap graph view.
Added hotkey Q to open and close bottom drawer.
* Fixed bug where timeline header and tracks could become horizontally
misaligned when using browser zoom.
* Fixed crash when hot-reloading Sass during development.
* Fixed bug where crashed debug tracks could not be closed.
* Fixed missing flame graph details for area selections.
* Consistent reporting of durations for incomplete slices.
* Switch to using prettier for formatting TS & Sass instead of ESLint.
SDK:
* "track_event" categories are disabled by default in the C API, if they
don't match anything in the data source config. This behavior differs from
the C++ API. Configs should include either `enabled_categories: "*"` or
`disable_categories: "*"` to explicitly specify the desired behavior that
work both for C and C++.
