+- Added the ability to cache the last region by @borgmanJeremy in https://github.com/flameshot-org/flameshot/pull/2615

+
+- Pinned screenshots can now be copied to the clipboard or saved to a file if a user right clicks on the pinned image by @zhangfuwen in https://github.com/flameshot-org/flameshot/pull/2519
+
+- Users can now specify their own Imgur API Key from ```Configuration > General > Imgur API Key```. This is encouraged because as Flameshot has gotten more popular we have started exceeding the upload limit of the default API key by@borgmanJeremy in https://github.com/flameshot-org/flameshot/pull/2503
+

+
+- Many Flameshot widgets have been reworked to use .ui XML files and Qt Designer. This has been done to allow non C++ developers to more easily contribute to the graphical side of Flameshot.
