Release Notes: New charset options were added for sending and receiving for better interoperability. More of the user interface is now sensitive to font size. More of the user interface can be translated. A popup list of matching contacts was added to the recipient entry box as you type. The "PLAIN" auth type and support for international folder names were added to the IMAP implementation. A crash in the font sub-system which occurred when more than 255 fonts are installed was fixed. Many additions were made to the HTML control (including new CSS property support). Many other optimizations and bugfixes were made.
