We’re halfway through 2025, and the pace of innovation isn’t slowing down one bit. This quarter, we doubled down on improving the developer experience with powerful video upgrades, refreshed tooling, and community-driven enhancements. Whether you're building secure video calls, integrating smart messaging flows, or improving your backend systems, we’ve shipped something just for you.
Here’s everything we launched in spring to help you build better.
The Vonage Video API saw a major release with version 2.30.0. This update introduced significant performance and security improvements. Highlights include End-to-End Encryption support for WebKit browsers, VP9 codec compatibility across platforms, and seamless session migration during server changes. Platform-specific enhancements were also introduced across Web, mobile, and desktop clients.

We released version 1.1 of the Vonage Video Reference Application for React. Built on developer feedback, this update includes key usability improvements: video pinning, improved mobile support, bug fixes, and stability improvements.

After months of work and over 39,000 lines of changes, the Vonage Java SDK v9.0.0 was released, along with the Kotlin SDK v2.0.0. These updates modernize and standardize the developer experience across all supported APIs.
These releases provide full test coverage, streamlined JSON and enum handling, and stronger typing across all return values. The updates also introduce support for new APIs, including SIM Swap, Number Verification, and a fully featured Conversation API.
In addition to expanded API coverage, the Messages and Voice APIs have been improved with simplified builders and webhook handling. The Kotlin SDK is now fully aligned with the Java version, offering a more consistent experience for developers working with JVM-based applications.
