This version contains many small improvements and bugfixes. Message Delivery Receipts and Entity Capabilities have been updated, as well as MUC support. Some features have been moved into their own modules (FIFO and url_regex). MCabber does not complain anymore when 256-color numbers are used in the configuration file, and a new "readmark" shows where each buffer was last read.
This major release is based on the Loudmouth library (which brings SASL and DNS SRV support, among other things) and has support for dynamic modules. Some improvements have been brought to the UI as well, like the attention sign, the buffer priorities, and Message Receipts.
