 ## Breakings changes
+### Version 0.5.0
+* As [`directories`] stopped being maintained we switch to [`directories-next`]. Both crates released a breaking change regarding default configuration path change on macos. For further information check their changelog.
+* The base functions `load` and `store` have been added an optionnal parameter in the event multiples configurations are needed, or ones with different filename.
+* The default configuration file is now named "default-config" instead of using the application's name. Put the second argument of `load` and `store` to be the same of the first one to keep the previous configuration file.
+* It is now possible to save the configuration as toml or as yaml. The configuration's file name's extention depends on the format used.
+
+### Version 0.4.0
 Starting with version 0.4.0 the configuration file are stored in the expected place for your system. See the [`directories`] crates for more information.
 Before version 0.4.0, the configuration file was written in the current directory.
