Cal.com's last open source changes before going closed source

Cal.com recently announced they're going closed source for security reasons. This is one of their last open source updates... they shipped an AI voice agent integration, Signal as a conferencing option, and a critical Salesforce security fix. Walking through the latest batch of Cal.com changes using gjalla's code reviewer. This one has a nice mix: a new AI voice agent app for phone-based scheduling, Signal added as a conferencing provider (good privacy option), audit locking extended to instant bookings, and a security fix for an app injection vulnerability in the Salesforce integration that's worth knowing about. This is part of an ongoing series where I pull upstream changes from major open source projects, run them through Gjalla's analysis, and walk through what actually matters — new features, security fixes, architecture decisions, and trade-offs that you won't catch just reading the changelog.
