What is CasparCG Server?

◆ Current state
CasparCG Server is an open-source broadcast playout server shipping one or two stable releases a year. 2.5.1 (September 16) removes the AVX2 requirement except for v210 Decklink output, updates FFmpeg to 8.1.2, and adds multi-device audio output, configurable audio and screen delays and an option to disable Decklink keying. 2.5.0 in December 2025 brought initial HDR, headless Linux and Ubuntu packaging.
◆ Where it's heading
After 2.5.0 set new baselines, 2.5.1 walks back the hardware one and spends the rest on stability: FFmpeg error handling, an AMCP BATCH race and Decklink av-sync recovery. The pattern is a feature-heavy .0 followed by fix-heavy point releases.
◆ Prediction
Expect further 2.5.x point releases before any 2.6 work appears; the entries show no 2.6 betas yet.
Fourwaves
5.0MEETINGS
Fourwaves doubles Free plan submissions to 50 and reworks reviewer assignment.
◆ Current state
Fourwaves ships small dated updates most days. November 11 raised the Free plan from 25 to 50 submissions, and November 12 added a four-step Assign reviewers window. Earlier in November it brought offline mobile check-in for Pro organizers and saved email templates for Advanced and Pro.
◆ Where it's heading
Most releases go to organizer tools for running the event and the review process, with features gated to paid plans. The Free plan increase is the first move in this run that widens the entry tier rather than adding to paid ones.
◆ Prediction
Expect more steps in the submission and review workflow to follow the new reviewer window; whether the Free plan change is part of a wider pricing revision is unclear from the entries.
