+## v1.50.0 (March 20, 2026)
+
+### Added
+
+- Added support for reading defined variables in `.nl` files (#2938)
+- Added `;generic_names` support to LP and MOF file formats (#2947)
+- Added add support for relaxing vector constraints (#2966)
+- Added support for [`ScalarCoefficientChange`](@ref) in
+  [`Utilities.MatrixOfConstraints`](@ref) (#2975)
+
+### Fixed
+
+- Fix `isapprox` for [`ScalarNonlinearFunction`](@ref) and comparison to Number
+  (#2934)
+- Fixed performance issue parsing each line of an MPS file (#2940)
+- Fixed MPS reader to allow the RHS name to be optional when reading (#2942)
+- Fixed [`Bridges.print_active_bridges`](@ref) for some constrained variable
+  cases (#2943)
+- Fixed error messages for unsupported keyword arguments in file format models
+  (#2946)
+- Fixed missing `Utilities.operate` in various `Bridges.Constraint.map_function`
+  (#2948)
+- Fixed a bug with open intervals in `Bridges.Constraint.SemiToBinaryBridge`
+  (#2963)
+- Fixed deleting some bridges before `Bridges.final_touch` was called (#2974)
+- Fixed a bug so that we re-throw appropriate errors when modifying constant
+  vector in [`Utilities.MatrixOfConstraints`](@ref) (#2976)
+
+### Other
+
+- Added ParallelTestRunner.jl to parallelize the tests (#2932), (#2960)
+- Removed Julia `1-ubuntu-latest-x64` from CI (#2935)
+- Added an explicit test for method redefinitions instead of parsing logs
+  (#2936)
+- Made minor formatting changes to the docs (#2939)
+- Installed `Dependabot` (#2949), (#2950), (#2951), (#2952), (#2953), (#2954),
+  (#2958), (#2968)
+- Add a new test for solving a multiobjective problem (#2970)
+- We experimented with an `LDLFactorizations.jl` package extension before
+  ultimately reverting it (#2933), (#2956), (#2959), (#2961), (#2972)
