What is OpenPhone?
OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.
OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.
What is Signal Desktop?
Signal Desktop's 8.36 beta adds favorite sticker packs after a fix-only week.
Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.36.0-beta.1 adds favorite sticker packs, so the ones a user relies on stay at hand. It follows the fix-only v8.35.0-beta.1 and v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling.

OpenPhone
0.0COMMS
OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.
◆ Current state
OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.
◆ Where it's heading
The core bet is an AI-handles-first-contact, humans-handle-edge-cases pattern. Each Sona release is closing a deployment-blocker (instructions, transfers, free trial), while the call-flow tooling underneath is getting more flexible so AI and human routing can coexist in one config. Plan-tier expansion (call hold on Starter) suggests OpenPhone is also chasing volume in the lower segment.
◆ Prediction
Expect Sona to gain CRM-aware context (caller history, deal state) and outbound use cases — proactive callbacks, scheduled follow-ups. Pricing for Sona usage is likely to evolve from a flat add-on toward usage- or outcome-based once volume appears.
Signal Desktop
5.0COMMS
Signal Desktop's 8.36 beta adds favorite sticker packs after a fix-only week.
◆ Current state
Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.36.0-beta.1 adds favorite sticker packs, so the ones a user relies on stay at hand. It follows the fix-only v8.35.0-beta.1 and v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling.
◆ Where it's heading
The desktop app is closing gaps with mobile one feature at a time, separated by maintenance betas. Visible features arrive about every two to three builds.
◆ Prediction
The next feature beta is likely within one or two builds, based on the cadence since October. The entries don't indicate what it will contain.
