# HOLOPLOT Plan 2.5.1

We're excited to announce HOLOPLOT Plan 2.5.1. This release introduces Zone Groups for organizing complex projects, a suite of bulk editing and selection tools, and more reliable .holoplot file import and export.

***

### What's New

#### Zone Groups

Manage complex projects with named collections of zones:

* **Create and Organize:** Create named Zone Groups directly from the Library panel or viewport, with show/hide controls and context menu access
* **Viewport Highlighting:** Highlight a Zone Group's zones in the viewport for quick visual reference
* **Export and Import:** Zone Groups are now included in .holoplot file export and import
* **Simulation Statistics:** View simulation statistics for selected Zone Groups
* **Beam-Zone Assignment:** Re-worked to support Zone Groups

#### Bulk Editing and Selection

New tools speed up working with large projects:

* **Shift-Click Range Selection:** Select a range of items at once in panel tree views
* **Bulk Entity Renaming:** Rename multiple entities in a single dialog
* **Bulk Zone Parameter Editing:** Edit zone parameters across multiple zone configs at once in Coverage Beams
* **Bulk Remove:** Remove multiple Zone Configs or Target Zones at once via the context menu
* **Assign Zones from the Viewport:** Assign zones directly to a beam using the new viewport context menu
* **Rename from Properties Panel:** Rename an entity directly from the Properties Panel

#### Improved .holoplot File Handling

* **Automatic Fixes on Import:** LF beams are not corrected upon import
* **Beam Coefficient Recovery:** Optimized Beam coefficients can now be recovered if required

#### Other Improvements

* **Beam Optimizations:** Updated to the latest version, meaning even better sounding beams!
* **Library Panel:** Reworked category filter tabs for easier browsing
* **DSP Performance:** Improved performance when switching Presets

### Bug Fixes

* Fixed an issue where Beam-instance user EQ, gain, and delay settings were sometimes lost on .holoplot import
* Fixed a crash that occurred when loading projects containing unknown module types
* Fixed an issue where very narrow zones were incorrectly rejected during zone validation
