First of all, this release contains important bug fixes. Furthermore, we optimized the way [expressions](http://mapsurfernet.com/docs/usermanual/expressions/index) are stored and processed. As a result, we were able to significantly reduce memory usage by WMS/WMTS services when a large number of map instances are involved. Note, that these improvements introduce some API changes which lead to the incompatibility with previously published versions. Therefore it is highly recommended to upgrade your previous installations.
Check out our [release notes](http://mapsurfernet.com/docs/release_notes/v2.3.0) for details about what is new in MapSurfer.NET 2.3.0.
