# 6.13.8

**MSSQL database connector:**

* Improved performance: MSSQL queries can become very slow in combination with using Flow variables. Added support for specifying a SQL type on the flow variable like: @MyVariable#VARCHAR

**Rest connector:**

* Deselecting output in REST Connector no longer leads to a crash
* Input fields with & in the name are not replaced with underscore
* Fix for floating-point numeric input from “wrong culture”

**Flow studio:**

* Resolved problems with user custom properties in application packages during runtime

**Workflow engine:**

* Fixed an error regarding variables not being resolved correctly with grid row & cell item styling when coming back from a paused state

**Server Tool:**

* Import is more OS agnostic. Added a dbonly flag so it is possible to import/export only databases (without the associated files)
