# Changelog

## v 1.96.3 (current) <a href="#v-1-71-current" id="v-1-71-current"></a>

### Bug Fixe&#x73;**:**

* Fixed compilation bugs on different versions of the engine

## v 1.95.4 <a href="#v-1-71-current" id="v-1-71-current"></a>

### Improvements:

* Added support for rotating probe groups in prefabs.
* Added a button for recombining the total volume to the Quick Editing component.

### Bug Fixe&#x73;**:**

* The volumes of the probes in the prefab can only be calculated from the prefab to avoid problems with the final positions.

## v 1.95.3 <a href="#v-1-71-current" id="v-1-71-current"></a>

### Improvements:

* The behavior of the "**Volumes List**" in the [MLP Manager](https://motiongamesstudio.gitbook.io/magic-light-probes/system-components-1/manager) depends on the state of the scene (prefab editing/main scene)
* "**Volumes List**" displays volumes for only one prefab instance.
* "**Calculate All Volumes**" button calculates volumes for only one prefab instance, the rest of the copies are updated after applying overrides.
* The method for searching for inner volumes has been moved to the calculating volume cycle and is now called only once, which should eliminate editor slowdowns with a large number of volumes on the scene.

### Bug Fixe&#x73;**:**

* Fixed bugs during project build.
* Fixed a bug due to which the calculation stopped at the stage "**Culling By Max Height**".

## v 1.95.2 <a href="#v-1-71-current" id="v-1-71-current"></a>

### Improvements:
