I’ve been able to put a lot of effort into new features in this release, thanks in great part to a burgeoning relationship with Vernal Creative. They make fantastic looking websites and have convinced some clients to underwrite new Geo Mashup features. Have a look at RSF Social Finance for an example. This is a promising new pattern that could really make Geo Mashup take off if it flourishes. A few good donors like Alphabet Travel have my thanks as well.
You should definitely look at the documentation before downloading and installing this release.
For the list of features added since the last beta release, see the documentation changes.
