+# CHANGELOG
+
+## Version 0.8.0
+
+### Important Changes:
+
+- Added an [initializer_example.rb](https://github.com/ddnexus/pagy/blob/master/lib/pagy/extras/initializer_example.rb) that you can use as an easy template for pagy configuration
+- Integrated extras from `pagy-extras` gem into pagy, now optionally required in the initializer
+- Refactored I18n: simpler code and simpler configuration now based on the `I18n` extra
+- Reorganized documentation and added a few more how-to topics
+- Added the `:page_param` variable used to get the page number from and create the URL for the page links
+
+
+### Breaking changes:
+
+- Extras are now integrated in pagy. The `pagy-extras` gem has been discontinued: you should remove it and update your code as indicated [here](https://github.com/ddnexus/pagy-extras)
+- Pagy I18n has been refactored and it's simpler to use. The main change is that the `Pagy::I18N[:gem]` variable has been removed, so if you want to use the `I18n` gem in place of the internal pagy implementation you need just to `require 'pagy/extra/i18n'` in your initializer. (see https://ddnexus.github.io/pagy/api/frontend.md#i18n)
+- `pagy_url_for` now requires the page_param argument and is called with 2 params: if you have overridden it, you should add the extra param.
+- `pagy_get_vars` now requires the vars argument and is called with 2 params: if you have overridden it, you should add the extra param.
+- `pagy_array_get_vars` now requires the vars argument and is called with 2 params: if you have overridden it, you should add the extra param.
