+- better handling messages with no id (shunf4)
+- removed dependency: uuid, now it's on Qt (shunf4)
+- better requesting latest history (shunf4)
 
 ### Improvements
 - slightly reduced the traffic on the startup by not requesting history of all MUCs
-- completely rewritten message feed, now it works way faster
+- completely rewritten message feed, now it works way faster and looks cooler
 - OPTIONAL RUNTIME dependency: "KIO Widgets" that is supposed to allow you to open a file in your default file manager
 - show in folder now is supposed to try it's best to show file in folder, even you don't have KIO installed
 - once uploaded local files don't get second time uploaded - the remote URL is reused
+- way better compilation time (vae)
+
+### New features
+- pasting images from clipboard to attachment (shunf4)

 Squawk requires Qt with SSL enabled. It uses CMake as build system.
 
+Please check the prerequisites and install them before installation.
+
+#### For Windows (Mingw-w64) build
+
+You need Qt for mingw64 (MinGW 64-bit) platform when installing Qt.
+
+The best way to acquire library `lmdb` and `boost` is through Msys2.
+
+First install Msys2, and then install `mingw-w64-x86_64-lmdb` and `mingw-w64-x86_64-boost` by pacman.
+
+Then you need to provide the cmake cache entry when calling cmake for configuration:
+
+```
+cmake .. -D LMDB_ROOT_DIR:PATH=<Msys2 Mingw64 Root Directory> -D BOOST_ROOT:PATH=<Msys2 Mingw64 Root Directory>
+```
+
+`<Msys2 Mingw64 Root Directory>`: e.g. `C:/msys64/mingw64`.
