 * Add `clean_qgis_layer` decorator back alongside with automatic cleaning [#45](https://github.com/GispoCoding/pytest-qgis/pull/45)
 
-
 ## Fixes
 
-* [#55](https://github.com/GispoCoding/pytest-qgis/pull/55) Allows using MagicMocks to mock layers without problems
+* [#53](https://github.com/GispoCoding/pytest-qgis/pull/53) Allow using MagicMocks to mock layers without problems
 * [#60](https://github.com/GispoCoding/pytest-qgis/pull/60) Allows using CRS properly again
+* [#62](https://github.com/GispoCoding/pytest-qgis/pull/62) Map does no longer zoom to the first added layer upon processing the events when using `qgis_show_map` marker
