# Change Log
## 1.5.0b1 23/05/2016
* Allow an IOS router to stop even the Dynamips hypervisor command fail to be sent. Ref #488.
* Extract private-config only when necessary (content is different than the default). Fixes #520.
* Fixes disabling the VPCS relay feature. Fixes #521.
* Fixes wrong exception in Docker VM implementation.
* Force Npcap DLL to be used first for Dynamips and uBridge (instead of the one from Winpcap if installed).
* Fixed startup-config is lost if you change any IOS router settings. Fixes #1233.
* Fixes check for NPF service and add check for NPCAP service on Windows.
* Fix ProcessLookupError X11VNC
* Force tag latest for docker image if no tag is specified
* Cleanup unbreakable space
* Do not raise error if vmrun.exe is named vmrun.EXE
* Load docker api only for Linux
## 1.5.0a2 10/05/2016
* Fix distribution on PyPi
