### Changed

* Updated What's New page

## [1.2.0] - 2023-01-02

### Added 

* Added support for removing vsync time, so we can see actual CPU duration over multiple frames. A drop down has been added to 'remove' a marker from the analysis and has entries for "FPS Wait", "Present Wait" and "Custom" where you can select any marker from the table using the right click context menu to "Remove Marker".
* Added optional standard deviation (SD) column into marker table (on single view) for sorting data based on variation of marker timings in over the frames.
* Added export of the comparison table as CSV.

### Changed

* Improved profile analysis performance.
* Updated minimal suppourted version to Unity 2020.3.

### Fixed

* Fixed bug when depth filter and marker vsync removal both applied.
* Fixed commas in CSV export file.

## [1.1.1] - 2021-10-04

### Fixed
* Fixed pulling frame data from the Profiler to exclude first and last frames if their main thread profiler data is incomplete, so that they don't skewer the analysis results [(case 1359686)](https://issuetracker.unity3d.com/product/unity/issues/guid/1359686/).
* Fixed IndexOutOfRangeException thrown when using Profiler or selecting Profiler frames in Profile Analyzer. [(1366931)](https://issuetracker.unity3d.com/product/unity/issues/guid/1366931/)

## [1.1.0] - 2021-07-23

### Fixed

* Fixed x axis display on frame time graph when capture doesn't match Unity Profiler contents.
* Fixed selected marker name to be updated even when Profiler fails to sync selection.

## [1.1.0-pre.2] - 2021-04-16

### Changed

* Ensured forward compilation compatibility of ProfilerWindow API usage.

### Fixed

* Fixed Frame View Dropdown not showing time in Microseconds when Microseconds are set as display unit type.
* Fixed ArgurmentOutOfRange exception on 'Clear Selection' usage in Frame Control.
* Improved loading and analysis progressbar progression to be monotonously incremental and reflect actual stage correctly.
* Fixed the marked frame time overlay so that it works on loaded data (case 1327888).
* Fixed keyboard frame controls so that they do not play an error sound (case 1327931).
* Fixed RangeSettings.IsEqual so that it doesn't throw an exception when there is a different dataView.selectedIndices.

## [1.1.0-pre.1] - 2021-02-22

### Changed

* Used the new `EditorWindow.docked` API on 2020.1 and later to replace reflection usage.  
* Made the **Thread Selection** window a utility window.
* Added a progress bar, which shows data loading progress.
* **All** no longer collapses in the thread view because it was superfluous and held no discernible purpose.
* Added information to the frame summary tooltip to show the selected ranges.
* Selecting the **Frame**, **Thread**, and **Marker Summary** title labels now also toggles their foldout.
* Timings in tooltips now display up to seven digits with a unit type change if below 0.01. This ensures the value is readable and correct.
* Frame Time Graph selection modifiers (Next, Previous, Grow, Shrink etc.) now work when multiple regions are selected.
* Added new (hidden) columns to the comparison tab for **Percentage Diff** for each of the diff types
* The **Depth Slice** drop-down is searchable and scrollable for Unity versions 2019.1 or newer.
* Improved tooltips on the top 10 marker duration time.

### Fixed

* The Thread Summary and Marker Summary views now correctly clip their contents when scrolling on 2018.4 and below.
* Marker detail bars are no longer drawn on top of the list's headers when scrolling.
* Fixed an issue with saving when there is no data loaded, which previously caused a null reference exception.
* **Add to** and **Remove from** name filter is no longer case sensitive.
* Optimized frame selection with **Show Filtered Threads** option enabled and **All Threads** turned on.
* Fixed an issue where the **Upper Quartile of frame time** option did not fit in the Graph scale dropdown in **Thread Summary**.
* Improved the error message when the Profile Analyzer fails to load a .data file.
* Fixed an issue where changing the depth slice and right-clicking on a marker caused an error in 2018.4 and earlier.
* Fixed the automatic increase of an unsaved file counter in Single view.
* Improved the Marker Column mode so that it is separate for Single and Compare view.
* The tooltip of the frame graph's scale control is now clearer and matches the documentation.
* Fixed an issue where a frame of '0' was incorrectly shown in the **Marker Summary** when the marker had a duration of 0ms.
* Fixed an issue with **Selection Synchronization** between Profiler Window and Profile Analyzer in Unity 2021.1 or newer.
* Added a log message when the loading or analysis fails due to domain reload.
* Fixed an issue with the table context menu, where it was not disabled during data processing.
* Fixed an issue where exporting a marker table that contained markers with commas or quotation marks to the .csv format would break the format.
