What is Seafile?

Seafile's server repo ships small hardening fixes across three branches at once.

The seafile-server repo tags fixes on the 14.0 and 13.0 lines and on SeaTable builds. The same commit is often tagged on several versions at once. Recent work is defensive: validating file-system object sizes, testing garbage collection under concurrent uploads, and checking errors on file copy. The one configuration change is support for a SEAFILE_DATA_DIR environment variable.

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.

Seafile vs Slack: editorial side-by-side

2.5

Seafile's server repo ships small hardening fixes across three branches at once.

◆ Current state

The seafile-server repo tags fixes on the 14.0 and 13.0 lines and on SeaTable builds. The same commit is often tagged on several versions at once. Recent work is defensive: validating file-system object sizes, testing garbage collection under concurrent uploads, and checking errors on file copy. The one configuration change is support for a SEAFILE_DATA_DIR environment variable.

◆ Where it's heading

The server core is in steady maintenance, with fixes backported across 13.0, 14.0 and SeaTable. The focus is data-integrity robustness rather than new capability.

◆ Prediction

Expect more 14.0.x patch tags with integrity and GC fixes; nothing in the entries points to new features.

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.
