Note: There is no guarantee that version mismatched client and server will
be able to talk with each other. Network protocol breakages won't be listed
here.
2018-05-25 19:24:18 +00:00
Note: Release numbers are nothing more than numbers. There are some
"missing" versions due to trace file changes during development. This is not
a mistake.

v0.3.1 (xxxx-xx-xx)
-------------------
2018-04-05 17:20:28 +00:00
2018-04-21 13:21:50 +00:00
- Breaking change: the format of trace files has changed.
- Previous tracy version will crash when trying to open new traces.
- Loading of traces saved by previous version is supported.
- Tracy will no longer crash when trying to load traces saved by future
versions. Instead, a dialog advising to update will be displayed.
- Tracy will no longer crash in most cases when trying to open files that
are not traces. Some crashes are still possible, due to support of old,
header-less traces.

- Ability to track every memory allocation in profiled program.
- Allocation event queuing must be done in order, which requires exclusive
access to the serialized queue on the client side. This has no effect on
the rest of events, which are stored in a concurrent queue, as before.
- You can search for a memory address and see where it was allocated, for
how long, etc. This lists all matching allocations since the program was
started.
- All active (non-freed) allocations may be listed. This shows the current
memory state by default, but can go back to any point in time.
- Graphical representation of process memory map may be displayed. New
allocations/frees are displayed in a bright color and fade out with
time. This feature also can look back in time.
2018-04-28 14:25:45 +00:00
- Memory usage plot is automatically generated.
2018-05-27 18:23:48 +00:00
- Basic allocation information is displayed in memory plot tooltips.
2018-05-02 16:20:28 +00:00
- A summary of memory events within a zone (and its children) is now
printed in zone info window.
2018-04-05 17:20:28 +00:00
- Support loading profile dumps with no memory allocation data (generated by
2018-04-14 13:47:09 +00:00
v0.2).
2018-04-05 17:31:46 +00:00
- Added ability to display global statistics of a selected zone from the
zone info window.
2018-04-09 12:29:22 +00:00
- Fixed regression with lock announce processing that appeared during
worker/viewer split.
- Allow selecting/unselecting all locks for display.
2018-04-20 21:29:02 +00:00
- Performance improvements.
2018-04-21 14:58:23 +00:00
- Don't save unneeded lock information in trace file.
2018-05-25 19:18:51 +00:00
- Don't save thrash in message list data.
2018-04-21 14:58:23 +00:00
- Allow expanding view span up to one hour, instead of one minute.
2018-04-21 22:58:17 +00:00
- Added trace comparison window.
- An external trace has to be loaded first.
- Zone query in both traces (current and external).
- Both results are overlaid on the same histogram.
2018-04-27 17:27:45 +00:00
- Graphs can be adjusted as-if there was the same number of zones
collected.
- Read time directly from a hardware register on ARM/ARM64, if possible.
- User-space access to the timer needs to be enabled in the kernel, so
tracy will perform run-time checks and fallback to the old method if the
check fails.
- Prevent connections in a TIME-WAIT state from blocking new listen
connections.
2018-04-28 14:46:53 +00:00
- Display y-range of plots.
2018-04-29 23:19:37 +00:00
- Added ability to unload traces loaded from files. To do so close the main
profiler window. You will return to the connect/open selection dialog.
Live captures cannot be terminated this way.
2018-05-02 17:28:04 +00:00
- Zones previously displayed in zone info window are remembered and you can
go back to them. Closing the zone info window or switching between CPU and
GPU zones will clear the memory.
2018-05-25 19:18:51 +00:00
- Improved message list window.
- Messages are now displayed in columns.
- Originating thread of each message is now included in the list.

-----------------
- Fixed broken TRACY_NO_EXIT behavior.
- Visual refresh (new color scheme).
- Added optional support for live in-depth zone analysis.
- Ability to search for zones matching a query.
- Histogram of zone time spans.
2018-03-20 13:39:10 +00:00
- List occurrences of a zone, grouped by thread, or by user text.
- Zone groups can be selected and highlighted on histogram graph.
2018-03-18 12:55:44 +00:00
- Support for linear and logarithmic display of time and values.
- Histogram bins can show zone counts or total execution time.
- Listed zones can be narrowed down by data range selection on histogram.
- Separation of server data handling code from the visualisation.
- Implementation of a command line capture utility.
- Support libraries have been updated.
- Fixed an issue that prevented de-duplication of source location payloads.
- Fixed an issue that prevented the ability to disable threads in settings
menu, if two threads had the same name.
- Performance optimizations.
- Visual clean up of the settings menu.
2018-03-28 00:00:29 +00:00

- Display zone stack trace.
2018-03-24 13:46:44 +00:00
- Hide pause/resume button if there's no data connection (i.e. trace was
loaded from file).
2018-03-24 14:22:08 +00:00
- Source location statistics view has been added.
2018-03-24 21:09:46 +00:00

was performed before.
2018-03-24 21:21:34 +00:00

executable.
2018-03-30 21:45:48 +00:00

delayed until first use of thread local variable.
2018-03-30 23:24:11 +00:00
- Store full thread name if pthreads (with 15 character name limit) are
used.
2018-03-31 12:14:49 +00:00
- Properly handle unaligned memory access (no performance impact).
