This release significantly enhances the migration feature with better performance and reduced disruptions, thanks to a complete overhaul of its logic.
We’ve also addressed numerous updates to the migration process itself, incorporating fixes and enhancements to better cover use cases raised by the community - thank you for your contributions!
Additionally, we’ve begun implementing new CLI commands to lay the groundwork for future plugin development, as part of the updated plugin design we’re actively working on.
Finally, thanks to the community again we’re introducing a new Status History panel, and the Table panel has been enriched with multiple improvements.
