v0.5.0 (unreleased)

Introduce thin strips above tracks that indicate tiny spans, merged spans, events, and CPU samples. This moves events out of the main track.
Add tooltips for spans in GC and STW timelines
Add shortcuts for opening traces and quitting Gotraceui
Don't slow down UI trying to compute accurate span durations
Display time spans in addition to (or in place of) durations
Display durations of flame graph spans in proportion to their parents, zoomed-on roots, and global roots.
Fix the display of call stack depth in the tooltips of stack spans
Reduce memory required to load traces by 20-30%
Reduce time required to load traces by 10-30%
Implement redo for navigations
Add support for traces produced by Go 1.22
Processor timelines more accurately represent processor states

v0.4.0 (2024-01-09)

Require Go 1.21 for building Gotraceui
All tables now have resizable and sortable columns
Added flame graphs
Links to timelines and spans now default to opening information
Links that open things and links that navigate use different colors (red and blue, respectively)
Clicking on spans in GC and STW timelines no longer crashes
Hovering table rows highlights them
When hovering timestamp links, their targets will be indicated in the timelines view
Spans have a new context menu item, to open their span information
Switch to a tabbed user interface instead of using multiple windows
Added a Goroutines tab that lists all goroutines in the trace
Panels can be converted into tabs
Added context menu to goroutine labels in timelines view
No longer create empty GC or STW timelines
Merged spans now display a detailed representation of the contained spans
Fixed a rare crash at startup
Fixed a rare crash for some traces
Handle DPI changes while Gotraceui is running
Display user-friendly strings instead of <unknown> for unknown timestamps
Hovered and highlighted spans are now indicated with a gradient instead of the border color
Span borders more accurately show if the span's beginning or end are outside the visible area
Merged spans no longer stop at the screen boundaries
Lowered peak memory usage
"active" spans in goroutine timelines now have a label
Improved rendering of graphs with many points

Added support for traces produced by Go 1.21
Improved the formatting of durations in statistics
Made minor improvements to visual appearance
Replaced foldables with a tabbed interface
Allow selecting and copying stack traces
Added list of spans to goroutine panel
Added parent goroutine to goroutine panel
Added statistics to spans panel
Added individual spans' stack traces in spans panel
Added function panel
Navigating to timestamps now places them at the configured axis origin
Fixed ctrl+scroll zooming on Windows
Fixed a crash when loading traces that start in the middle of a task
Truncate long span labels instead of hiding them
Added a button to select all instances of a user region
Added histograms
Stop-the-world spans now display the reason for the STW
Made various performance improvements
Drastically lowered memory usage for traces with a lot of deep call stacks
Holding shift while scrolling vertically will cause horizontal scrolling, and vice versa
The info panel of user regions now displays events that occurred on the goroutine during said regions
Improved accuracy of computation of durations of merged spans
Added more features to the context menu of span links
Expensive computations, such as creating goroutine statistics, now run in the background and no longer prevent the UI from updating.

Added a button for copying statistics as CSV
Added context menu to links to processors
Added a list of spans to the span panel for merged spans
Added display of span tags in span panel
Added a dialog for highlighting spans based on their states
Automatically turn off the memory graph's "auto-extents" feature when manually resetting the extents
Syscall spans now include the syscall's name in the span label
Toggling compact mode now keeps the timeline under the cursor at its position
Disabling stack tracks or compact mode ensures the cursor stays on the current timeline
Improved the formatting of durations in statistics
Minor performance improvements
Fixed the display of the ⌘ sign in shortcuts
Fixed displaying context menus in additional windows
Fixed crash when clicking on link to processor
The checkboxes for filtering event lists now wrap to multiple lines if necessary
Minor improvements to the manual
