The list of new features as well as fixed bugs can be found in our change log at https://dev.ladesk.com/all/
We are constantly working on developing new features and fixing occasional bugs in the LiveAgent application. New versions are usually released about once in 4 weeks, but the interval may vary.
The version number consists of 4 numbers separated by dot e.g. 4.18.1.3
On each planned major release, the second number is incremented e.g. from 4.18 to 4.19.
There may be unplanned so called "hotfix" releases when the second numer is not incremented. These usually contain some critical fixes which can't wait until next planned major release. This version may not contain changes announced to be released in "next" version.
The third number is incremented for each database update of the major version. If major version doesn't contain any database changes, this number will be 0. e.g. 4.18.1.3 would contain 1 database change.
The last number is incremented on each build of the Application, so for example if a "hotfix" version contains only minor changes in application code, only the last number would be incremented e.g. 4.18.1.3 to 4.18.1.4
