 ### Bug Fixes
 
+- `slackdump resume -refresh -member-only` now skips newly discovered public
+  channels that the current user has not joined (#758). Channels already in
+  the resume list are still processed.
+- Fixed MCP archive switching so `load_source` waits for active reads before
+  closing the previous archive (#753). Failed opens or canceled waits leave
+  the previous archive active, queued reads can be canceled, and the server
+  closes the active archive at shutdown.
 - Fix slow database deduplication on large channels (#750), including cleanup
   after `resume -dedupe`. Existing archives automatically build a message index
   on first open after upgrading; this can take extra time and disk space.

+### Discovering new channels.
+
+Use `-refresh` to discover additional channels while resuming an existing
+archive. Add `-member-only` to skip newly discovered public channels that you
+have not joined:
+
+```plaintext
+slackdump resume -refresh -member-only <archive>
+```
+
+The membership filter applies to newly discovered channels. Channels already
+in the resume list are still processed, even if you are no longer a member.
