# [v3.0.0-alpha5](https://gitlab.com/openflexure/openflexure-microscope-server/compare/v3.0.0-alpha4...v3.0.0-alpha5) (2026-04-08)
The fifth alpha release of the server. This release has been a huge amount of work and brings us significantly closer to a semi-stable beta release. Some highlights are:
* Move from LabThings Dependencies to ThingSlots. This has allowed for:
* Much easier communication between Things
* Static type checking
* Simpler action creation.
* Created ScanWorkflows, a backend change that allows switching scan methods. Enabling new types of scanning:
* Raster Scan
* Snake Scan
* CChip Scan (experimental, requires a configuration change to use)
* Transition front end from the end of life Vue2 to Vue3 which is in active development!
* Improvements to the simulation microscope including more simulation samples and camera options. Speeding up development.
* Improved testing, including better defined testing environments, separation of integration and unit tests, and tests passing on Windows
* OpenCV camera switching. Enabling changing between cameras in settings when in manual configuration.
* "Jogging" movement. The microscope can now move continuously when an arrow key is held.
* Improved server side UI specification. This brings us closer to "Things" being able to define their own tab, which will soon enable plugins in v3.
* A user interface for recentring and range of motion.
* Improved fallback server interface.
* Backlash correction in scanning.
* A huge number of other bug fixes and improvements.
The following merge requests have been merged into v3:
