Version 1.0.3019.1151

  • Introduced C API to Superluminal. The C++ API has been deprecated but will continue to function. New features will be added to the C API exclusively.
    • The C API can be found in PerformanceAPI_capi.h in the API directory in the Superluminal installation folder.
    • The InstrumentationScope and related macros are not deprecated and will continue to function.
  • Added support for coloring Instrumentation events to the API. Colors can be created through the use of the PERFORMANCEAPI_MAKE_COLOR macro.
  • Added context menu to the Function List headers. This allows you to hide/show columns, similar to the Call Graph.
  • Added Open In Editor button to the Source view. This button will open the current source file in the associated editor.
  • Added support for running Superluminal behind a proxy server. Superluminal will now automatically detect and use the proxy server, if necessary.
  • Fixed bug in Instrumentation Timings view: clicking on a bar will now correctly update the Call Graph again.
  • Fixed rare hang in the Source view, caused by the network port being stolen by another program.
  • Fixed support for Fibers in 64-bit applications.

Version 1.0.2952.1148

  • Fix for fiber support in 32-bit applications

Version 1.0.2948.1147

  • Added syntax highlighting for Rust files
  • Added support for demangling Rust symbol names
  • Fixed display bug in Instrumentation Timings window when there are a large number of instrumentation events in the trace
  • Fixed rare crash in symbol resolving when the target program has been linked by lld, caused by invalid debug data being emitted by lld

Version 1.0.2935.1144

  • The selection mechanics have been completely reworked
    • The timerange is only ever set by the user. When clicking on a function, we do not automatically make a timerange selection anymore. This makes it also possible to continue clicking on functions while having an active timerange, making navigation with the callgraph a lot easier.
    • All views are always filtered to the active timerange. The option to choose between 'entire session/selected timerange' has been removed from all UIs. If there is no active timerange, data for the entire session is displayed.
    • Find results separated. The Find results are now separate from your selection. This means you can now click through/interact with your Find results without losing them. 
    • Highlight changes. The Find result highlights are always displayed in yellow. The highlights that indicate your selection in the callgraph/function list are now always white.
  • We'd love to hear what you think of these changes!
