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

Adds support for lambda expressions in curly braces in C++ function names. #175

Changed

Stop pruning () expressions in template position. #174

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)

Changed

Replace chashmap with dashmap (#155 by @koushiro)
Replace fnv with ahash (#155 by @koushiro)
Update some outdated dependencies (#155 by @koushiro)
Upgrade MSRV to 1.40.0 (required by dashmap) (#155 by @koushiro)

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
