Merging a lane means taking a snap of a component from a lane, and merge it back to the component.
To merge all snaps in your lane to another, first get all components of a lane, and then use the merge sub-command
bit lane switch myorg.myscope/my-lane --get-all bit lane merge main
This merges all changes for all components in the lane to the main lane. Bit creates a snap for each component, highlighting the merge that has happen.
You can now decide to tag a new version.
bit tag --all --message "new version after merge"
