CasparCG Server v2.3.0 LTS Beta 1

CasparCG 2.3.0 LTS Beta 1

It's here, the first LTS version ever of CasparCG Server! Even if it is a beta release we have been all working hard to make this happen. As the name indicates we have been working and focusing on stability and reliability in this version. We have also done smaller improvements to the performance compared to the previous version.

CasparCG Server v2.3.0 LTS Beta 1 can be downloaded directly from this release (see attachments).
