-- all of the expandable roster items now get saved between launches
-- settings file on the disk is not rewritten every roster element expansion or collapse
-- removed unnecessary own vcard request at sturtup (used to do it to discover my own avatar)
-- vcard window now is Info system and it can display more information
-- reduced vcard request spam in MUCs
-
-### New features
-- now you can enable tray icon from settings!
-- there is a job queue now, this allowes to spread a bit the spam on the server at connection time

-- message height is now calculated correctly on Chinese and Japanese paragraphs
-- the app doesn't crash on SIGINT anymore
-
-### Improvements
-- there is a way to disable an account and it wouldn't connect when you change availability
-- if you cancel password query an account becomes inactive and doesn't annoy you anymore
-- if you filled password field and chose KWallet as a storage Squawk wouldn't ask you again for the same password
-- if left the password field empty and chose KWallet as a storage Squawk will try to get that password from KWallet before asking you to input it
-- accounts now connect to the server asynchronously - if one is stopped on password prompt another is connecting
-- actualized translations, added English localization file
-
-### New features
-- new "About" window with links, license, gratitudes

-- what() method on unhandled exception now actually tells what happened
-
-### New features
-- the settings are here! You con config different stuff from there
-- now it's possible to set up different qt styles from settings
-- if you have KConfig nad KConfigWidgets packages installed - you can choose from global color schemes

-- 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 and looks cooler
+- completely rewritten message feed, now it works way faster
 - 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

-#### For Windows (Mingw-w64) build
-
-**Building for windows is not mainteined, but was possible in the past, you can try, but it probably won't work**
-
-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:
-
-`<Msys2 Mingw64 Root Directory>`: e.g. `C:/msys64/mingw64`.

+Here is the list of keys you can pass to configuration phase of `cmake ..`. 
 - `CMAKE_BUILD_TYPE` - `Debug` just builds showing all warnings, `Release` builds with no warnings and applies optimizations (default is `Debug`)

-- `SYSTEM_LMDBAL` - `True` tries to link against `LMDABL` installed in the system, `False` builds bundled `LMDBAL` library (default is `True`)

-  <description>
-    <p>
-      Squawk is a lightweight XMPP desktop messenger.
-      The primary objective of this project is to offer
-      you a fast and user-friendly messaging experience
-      that closely aligns with your system’s style, while
-      also minimizing resource consumption.
-    </p>
-    <p>
-      Squawk is still at a very early stage and might not suit
-      everyone but you are welcome to try it out.
