There have been considerable improvements to the collect and export functionality:

• Renamed embark-collect-completions to just embark-collect, and embark-collect-live to embark-live. Their implementations were also significantly simplified. Also, embark-collect-completions, which was hardly used, has been removed.
• Collect and export buffer have descriptive names now.
• Collect buffers have a dired-like marking functionality now, making it easy to use embark-act-all on arbitrary subsets of candidates.
• Collect buffers support group-function with a collapseable outline.
• Added flexible "half-revert" functionality for collect and export buffers: pressing g will rerun the command the candidates were obtained from and re-enter the input you had, so you can tweak the input and re-collect or re-export if you like.

Besides changes to collect and export, there have been several other miscellaneous improvements, maybe chief among them making the insert and "save to kill-ring" actions support multiple targets.
