7.0.0

Introducing "Virtual Geometry" surfaces that can be embedded within the geometry and which respond to alignment corrections in the same way as material geometry. These surfaces do not have any material composition but they can be used in tracking, either during simulation or reconstuction. For instances are provided with this release:  Rectangular, Trapezoidal, Diamond-shaped, and Annular. The last of these is inspired by a particular surface occurrring in ATLAS.  Input output of these surfaces is provided.  Visualization is also provided.

6.5.0

New or improved functionality in GeoShape:

    User can now specify the number of random points to be used for estimation the volume, the default is 1M points
    Volume can be set or returned from the shape 
    Test for whether the volume is a polyhedron or not. 
    Total number of constituents can be queried.
    More efficient computation of Boolean volumes

6.4.0

The format of information in the AAHEADER file has changed from the previous version.

6.3.0

6.2.1

Bugfix:  Input/Output for GeoUnidentifiedShape is fixed.

6.2.0

6.1.0

This version adds proper persistification of GeoGenericTrap and GeoTorus under the new DB schema, and suppresses some extraneous output.

6.0.0

This release introduces a modification to the database schema:  floating point data is now stored with a floating point (rather than ASCII) representation in the database.

Important note!  all databases created prior to this tag (version 6.0) will be unreadable!

5.6.0

* Restructure the classes to allow the introduction of Virtual Geometry (aka Tracking Surfaces)
* Allow for mutable materials in GeoLogVol.  Useful for gases and other stuff which can be piped in.

5.4.0

5.3.0

* Typo fix in the deduplication of full physical volumes
* Introduce `cloneVolume()` helper function
* Augment the early testing capability against Athena
* Disable by default deduplication mechanisms
* Deduplication steering flags moved into the processor registries
* Disabled cloning in resize of GeoATLAS by default
* `gmcat`: don't fail if the local GeoModelData git repository is not accessible

5.2.0

Creating of 5.2.X changes w.r.t 5.1
```
* Typo fix in the deduplication of full physical volumes
* Introduce cloneVolume helper function
* Augment the early testing capability against athena
* Disable by default deduplication mechanisms
```

5.2

Changes w.r.t. 5.1

- Bug fixes when GeoPhysVols with Full physical volumes as children are deduplicated
- Add functionallity to the GeoDeDuplicator to switch off deduplication of Shapes, LogVols, GeoTransforms
- Disable deduplication by default
- Augment early testing in Athena  to test simulation & MC simulation in the CI
- Memory leak fix in GeoElement
- Introduce clone helper function to GeoHelpers.

5.1.0

* GeoModelFunctionSnippets renamed to GeoModelHelpers.
* De-duplication code is in place, which can be used to share Shapes and Physical Volumes automatically.
* The material manager code is simplified and put in one place.
* Several cosmetic changes in the gmcat utility

5.0.4

* GeoModelFunctionSnippets renamed to GeoModelHelpers.
* De-duplication code is in place, which can be used to share Shapes and Physical Volumes automatically.
* The material manager code is simplified and put in one place.

5.0.3

* Fix move semantics avoiding leakage of reference counts once the absolute position of a volume is requested.

5.0.2

* Remove explicit from default constructor
* Add possiblitiy to construct IntrusivePtrs from Child classes.

5.0.1

Patched `GeoIntrusivePtr` by adding template specification of the comparison operator. This was necessary for fixing C++ 20 compiler warnings

5.0.0

This release  introduces the IntrusivePtr, which automatically increases/decreases  the reference count of pointed-to objects with pointer construction/destruction. 

Other changes:  default transform for Alignable transforms are now persistified in  GeoModelWrite, rather that aligned positions. 
Convenience functions for input/output are added.

4.6.0

The main changes affect GeoModelKernel and GeoModelIO:

* For the GeoVGeometryPlugins, the interface was changed.  Now written to the GeoVPhysVol interface, allowing either full or ordinary phy vols to be created from a plugin.
* Bug fix in GeoModelWrite (all phys vols stored and phys vols) and greater generality in GeoModelRead (either fullphysvols or physvols are resolved at the top of the geometry tree)
* Update GeoModelExamples, GeoModelTools, and GeoModelVisualization to new interfaces
