Post-V5 releases are spent making the AI agency actually usable rather than adding to it.
A side-by-side editorial comparison of Notion and Vonage — release velocity, themes, recent moves, and the top alternatives to consider.
Notion is building the place where other companies' agents come to work
The 3.5 and 3.6 releases turned Notion into a developer platform: Workers run custom code on Notion's infrastructure, a CLI and Markdown API exist for coding agents, and External Agents bring Claude and Cursor onto a shared board where a team can assign and watch them. Custom Agents have accumulated the surrounding machinery in the weeks since — five more MCP connections, calendar tools, Outlook mail, Microsoft file read and write, audit-log coverage, and a people directory. The most recent entries are smaller and mostly about wiring: sharing context from the Share menu, sharing Workers across a team, and surfacing Worker usage in the credits dashboard before the free beta ends.
Vonage's tracked feed shows only SDK version bumps, and it went quiet after October 2025.
Everything captured here is server-SDK release plumbing — Ruby, .NET, Java, Kotlin, Node, iOS — with no release notes beyond a version string and a date. Several rows are not releases at all but scraped navigation chrome from the changelog index, which means the parser is picking up page furniture alongside real versions. The most recent genuine entry is a Ruby SDK bump from October 2025.

Notion is positioning itself as the orchestration layer rather than another agent vendor, which is a different bet than most of its competitors are making. The supporting work is consistent with that: Workers to run the code, a credits dashboard to price it, an audit log to govern it, and sharing so one person's Worker becomes a team asset. The recent shift from platform launches to permissions, sharing and billing surfaces is what a product does after the capability lands and adoption becomes the constraint.
Workers move onto paid credits on August 11, so the near-term work should keep clustering around usage visibility and cost controls. The trigger surface is the other thread to watch — meeting notes became an agent trigger this window, and the same pattern applied to other Notion events is the obvious next step.

Nothing about Vonage's actual product direction is visible through this source; the CPaaS platform work happens elsewhere, and only its client-library releases surface here. On the evidence available, the feed reflects routine multi-language SDK maintenance across a mature API surface rather than any shift in capability. The nine-month gap since the last captured release suggests the source itself has stopped updating rather than that Vonage stopped shipping.
Insufficient data for a directional call: the feed is stale and carries no release notes, so any prediction would be about the crawler rather than the product.
