Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
A side-by-side editorial comparison of Slack and Zoho Cliq — release velocity, themes, recent moves, and the top alternatives to consider.
Slack now hosts any A2A agent without Slack-specific code.
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
Zoho Cliq's latest post makes the case for WCAG accessibility after its MCP tools launch.
Cliq 7.0 shipped in August with AI summarisation, a developer platform refresh and Cliq Mini across Zoho apps. September added reworked guest access, Cliq Rooms on Neat hardware and per-role subscription plans, and October brought MCP tools so automations can be written with an AI coding assistant. The newest post argues that Cliq's WCAG compliance makes it usable for employees with disabilities, without announcing anything new.

Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.
Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.

Cliq is spreading in two directions: outward into meeting rooms and other Zoho apps, and toward developers through its platform and MCP tools. Recent posts lean on positioning rather than releases.
It is unclear from these entries what ships next; a follow-up on the MCP tools or another 7.x feature post is most likely.
