+- Fixed some errors around dynamic changes of `ax.xscale` or `ax.yscale` [#3084](https://github.com/MakieOrg/Makie.jl/pull/3084)
 - Improved Barplot Label Alignment [#3160](https://github.com/MakieOrg/Makie.jl/issues/3160).
 - Fixed regression in determining axis limits [#3179](https://github.com/MakieOrg/Makie.jl/pull/3179)
 - Added a theme `theme_latexfonts` that uses the latex font family as default fonts [#3147](https://github.com/MakieOrg/Makie.jl/pull/3147).
