We also see memory leaks on client side in v1.5.377.21, might this be related to this?

[romanett]

@RicoSuter this fix is purely Server side. Please open an Issue with more Details about the memory leak.

[RicoSuter]

@romanett i see it’s fixed within the master branch. When csn we expect another full release of master?

[romanett]

@RicoSuter We will release a "Preview" on nuget in the coming days. If no Issues are reported a regular release will follow in some weeks.
