  - Added `SplitComplexZerosBridge` and `SplitComplexEqualToBridge` which bridges
    complex-valued equality constraints into their real and imaginary parts
- - Added support for generic nunmber types in `Utilities.loadfromstring!`
+ - Added the `HermitianPositiveSemidefiniteConeTriangle` set, with bridges to
+   `PositiveSemidefiniteConeTriangle`
+ - Added support for generic number types in `Utilities.loadfromstring!`
  - Add new optimizer-independent options `RelativeGapTolerance` and
    `AbsoluteGapTolerance`
  - Updated `FileFormats.MOF` to MathOptFormat v1.1, enabling support for
    constraint programming sets in the `MOF` file format
  - Added support for quadratic constraints and an objective to `FileFormats.MPS`
  - Added support for indicator constraints to `FileFormats.MPS`
+ - Added support for quadratic constraints and an objective to `FileFormats.LP`
