+ - Add `FileFormats.NL.read!(::IO, ::Model)`
+ - Add `MOI.modify` that accepts a vector of modifications
+
+### Bug fixes
+
+ - Fixed a bug in `Test` which attempted to include non-`.jl` files
+ - Fixed a bug in `FileFormats` for models with open interval constraints
+
+### Performance and maintenance
+
+ - Fixed a performance issue in `Utilities.DoubleDict`
+ - Various minor improvements to the documentation
