What is FreshRSS?

FreshRSS ships two security releases in a day for PHP CVEs and moves Docker to Debian 13.

FreshRSS has issued four 1.30.x security releases since the 1.30.0 change that blocked local network access by default. 1.30.3 and 1.30.4, both on Oct 21, patched severe PHP vulnerabilities in the official Docker images: Debian first, now on Debian 13 Trixie, then Alpine. The project points users who want faster patches to its rolling edge channel.

What is Slack?

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.

FreshRSS vs Slack: editorial side-by-side

F
FreshRSS
COLLAB
5.0

FreshRSS ships two security releases in a day for PHP CVEs and moves Docker to Debian 13.

◆ Current state

FreshRSS has issued four 1.30.x security releases since the 1.30.0 change that blocked local network access by default. 1.30.3 and 1.30.4, both on Oct 21, patched severe PHP vulnerabilities in the official Docker images: Debian first, now on Debian 13 Trixie, then Alpine. The project points users who want faster patches to its rolling edge channel.

◆ Where it's heading

The 1.30 line has become a security maintenance branch, and new features wait for the next major. The team is treating its Docker images as part of the product it must patch, not just the PHP code.

◆ Prediction

More 1.30.x point releases are likely as upstream PHP and base-image fixes land; new features probably arrive with 1.31.

Slack now hosts any A2A agent without Slack-specific code.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
