Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
A side-by-side editorial comparison of Fonoster and Vonage — release velocity, themes, recent moves, and the top alternatives to consider.
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.
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.

After a quick run of voice-AI options, Fonoster has turned to what a hosted service needs before paying customers rely on it: legal pages, billing correctness, webhook debugging and account deletion that actually removes data. The cadence stays daily and the changes stay incremental.
More account and billing lifecycle work is likely next, since v0.57 adds a billing test case and deletion rules in the same release.

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.
