 - `test_ambiguities` now excludes the keyword sorter of all `exclude`d functions with keyword arguments as well. ([#203](https://github.com/JuliaTesting/Aqua.jl/pull/204))
 - In `test_deps_compat`, the two subtests `check_extras` and `check_weakdeps` are now run by default. ([#202](https://github.com/JuliaTesting/Aqua.jl/pull/202)) [BREAKING]
 - `test_deps_compat` now reqiures compat entries for all dependencies. Stdlibs no longer get ignored. This change is motivated by similar changes in the General registry. ([#215](https://github.com/JuliaTesting/Aqua.jl/pull/215)) [BREAKING]
+- `test_deps_compat` now requires a compat entry for `julia` This can be disabling by setting `compat_julia = false`. ([#236](https://github.com/JuliaTesting/Aqua.jl/pull/236)) [BREAKING]
 - `test_piracy` is renamed to `test_piracies`. ([#230](https://github.com/JuliaTesting/Aqua.jl/pull/230)) [BREAKING]
 - `test_ambiguities` and `test_piracies` now return issues in a defined order. This order may change in a patch release of Aqua.jl. ([#233](https://github.com/JuliaTesting/Aqua.jl/pull/233))
 - Improved the message for `test_project_extras` failures. ([#233](https://github.com/JuliaTesting/Aqua.jl/pull/233))
