+**Rendering options for fonts**
+
+When loading fonts with the function renderer.font.load some rendering options can
+be optionally specified:
+
+- antialiasing: grayscale or subpixel
+- hinting: none, slight or full
+
+See data/core/style.lua for the details about its utilisation.
+
+The default remains antialiasing subpixel and hinting slight to reproduce the
+behavior of previous versions.
+The option grayscale with full hinting is specially interesting for crisp font rendering
+without color artifacts.
+
+**Unix-like install directories**
+
+Use unix-like install directories for the executable and for the data directory.
+The executable will be placed under $prefix/bin and the data folder will be
+$prefix/share/lite-xl.
+The folder $prefix is not hard-coded in the binary but is determined at runtime
+as the directory such as the executable is inside $prefix/bin.
+If no such $prefix exist it will fall back to the old behavior and use the "data"
+folder from the executable directory.
+
+In addtion to the `EXEDIR` global variable an additional variable is exposed, `DATADIR`,
+to point to the data directory.
+
+The old behavior using the "data" directory can be still selected at compile time
+using the "portable" option. The released Windows package will use the "data"
+directory as before.
+
+**Configuration stored into the user's home directory**
+
+Now the Lite XL user's configuration will be stored in the user's home directory under
+".config/lite-xl".
+The home directory is determined using the "HOME" environment variable except on Windows
+wher "USERPROFILE" is used instead.
+
+A new global variable `USERDIR` is exposed to point to the user's directory.
