This release includes minor bug-fixes, minor GUI updates, some speed improvements, and support for ARMAX (ARMA with exogenous input) models.
There is also a new class of object, a "data source". For now the only source is a link to a .csv or .tsv file. But in theory this source could be connected to a variety of different sources: internet pages, broker APIs, databases, etc.
The User's Guide has been updated a little (thanks to asafarim for feedback in reviewing the last version), although it still has a way to go, and needs to be connected to the help menu somehow.
