Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
A side-by-side editorial comparison of Heymarket and Fonoster — release velocity, themes, recent moves, and the top alternatives to consider.
Heymarket's feed argues for conversational AI without confirming it ships any.
Seven entries, all explainer content: conversational AI in retail, multilingual support, chatbot versus conversational AI, AI data enrichment, RCS versus SMS, and shared inboxes. Bodies are truncated after roughly two sentences, so each entry gives a scenario and a promise with the substance behind a link. Nothing here is a release note.
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.

The topic mix has shifted decisively toward AI handling inbound messages rather than routing them to people — repetitive retail questions, languages the team doesn't speak, after-hours requests. That is a clear statement of where Heymarket wants to compete in business messaging. Whether its own product does these things, or the posts are describing the category, cannot be resolved from these entries.
Expect the AI-support content to continue and RCS coverage to expand as carrier support broadens. A claim about Heymarket's actual capabilities would need the full articles, which this feed truncates.

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.
