0.10.1 - 2020-10-05

Added

  • Support kernel annotations for versioned vmlinux and kernel modules in collapse-perf. #182
  • Support of AsyncProfiler generated stack trace in java palette. #183
  • --deterministic for deterministic colors without weighting. #190

Changed

  • Trimmed down a few unnecessary dependencies. #188

0.10.0 - 2020-06-20

Added

  • Flame chart mode. Flame charts put the passage of time on the x-axis instead of the alphabet. #125
  • cargo hack to check that all features compile. #181

Changed

  • All Options are now marked as #[non_exhaustive] so that we can add options without making that a breaking change. This also makes feature-dependent fields (like func_nameattr on flamegraph) okay. Unfortunately, it also means that function record update syntax won't work any more (Options { ..., ..Default::default() }). See rust-lang/rust#70564 (comment) for details. #181

0.9.9 - 2020-06-03

Changed

  • In icicle/inverted mode, the details bar is now at the top where it can actually be seen. #177

Changed

  • Fixes a regression where anonymous namespaces would be pruned. #175
  • Adds support for lambda expressions in curly braces in C++ function names. #175

0.9.7 - 2020-05-29

Changed

  • Stop pruning () expressions in template position. #174

0.9.6 - 2020-05-07

Added

  • Support for combined event/stack lines. #168

Changed

  • Fix crash on empty traces. #168
  • Also parse last sample in file. #168

0.9.5 - 2020-03-18

Added

  • Add a new color option, color diffusion, that makes wider frames redder. This visually draws the eye towards places that need optimization. #165 by @itamarst.

0.9.4 - 2020-02-02

Changed

  • Fix bug where subtitles would often be hidden (#161 by @itamarst)

0.9.3 - 2020-02-02

Added

  • Overly long frame lanes can be shortened either on the left or the right (#157 by @itamarst)

Changed

  • By default, overly long frame lines are now shortened on the left (#157 by @itamarst)

0.9.2 - 2020-01-30

Changed

0.9.1 - 2019-10-31

Added

  • Support for collapsing the CSV output of the VTune amplxe-cl tool (#148 by @jasonrhansen).

Changed

  • The sample collapser now returns errors where it used to just log them in places where it doesn't make sense to continue.

0.9.0 - 2019-09-11

Changed

  • Support for multi-threaded collapsing was moved behind the multithreaded feature flag which is on by default (#146).
  • The structopt dependency has been updated, which bumps the minimum supported Rust version to 1.36.0 (#145).
  • Support for nameattr files was moved behind the nameattr feature flag which is on by default (#147).

Removed

  • The demangle option for collapsers; we instead rely on the sample generator to demangle names, and then just do some post-processing fixups for common issues (#144).
  • The dependency on rand. Reduces the footprint of the crate, and also makes the random color choices seeded by the same number each run (#146).

0.8.0 - 2019-07-24

Added

Changed

  • Moved to IndexMap and FNV hashing (#127)
  • Moved CI to Azure DevOps Pipelines
