# HOLOPLOT Plan 2.4

### New in HOLOPLOT Plan 2.4 🚀

This release focuses on advanced system configuration and alignment workflows, developed to support complex, real-world deployments and large-scale venue installations. It introduces major improvements to Function Groups, downmix routing, and .holoplot file interoperability, alongside simulation, optimisation, and workflow enhancements.

***

### What’s new and improved?

#### Function Groups

Function Groups are now fully supported in Plan 2.4, enabling more structured and scalable system design.

* Create and edit Function Groups
* Move beams between Function Groups
* Apply EQ at the Function Group level

This enables higher-level control and consistency across complex systems.

***

#### Delay Downmix Matrix

The Delay DownMix Matrix has been introduced and is now available per layer.

New capabilities include:

* Establish routing connections per layer
* Edit crosspoint gain and delay values
* Copy & paste routing
* Sorting
* Bulk connect and disconnect operations

Additional workflow improvements:

* Gains and delays can be pulled from or pushed to beam-level values
* Simulation now updates dynamically in response to downmix changes

***

#### Module Group Creation

Module Groups can be created using the dedicated Module Group creation tool in the toolbar. This allows you to:

* Select subsections of an array, and create beams only using specific modules within the same array<br>

This provides greater flexibility when designing complex systems, enabling you to create beams using parts of array.

***

### Known issues

* If an optimisation job returns an error due to *“Job not found”*, retrying may fail
  * Workaround: cancel the job and restart the optimisation
* Downmix connections are not preserved when copying or duplicating a layer
