## Release Notes
## Latest stable version
Version: 4.0.2
Released: 05/05/2021  
[![DOI](https://zenodo.org/badge/283332126.svg)](https://zenodo.org/badge/latestdoi/283332126)

### Version 4.0 is the first public release.
* Future edits will use [semantic versioning](https://semver.org/) (major.minor.patch; e.g. 0.0.0).  
* _Patches_ are minor bug fixes, as long as they don't change the expected functionality of existing codes(e.g. 4.0.**1**).
* _Minor_ modifications, including feature additions and more substantial fixes will go to sub-version (e.g. 4.**1**.0).
* _Major_ feature change that creates different functionality for existing tools will get a full new version number (e.g. **5**.0.0).

## Version pointers
`GTDef/GTdef/stable` will point to the latest stable release.
`GTDef/GTdef/unstable` will point to the current development version.

## Software/Packages required
1. Modern version of Matlab
1. The following toolboxes are required for base operation:
	- Optimization Toolbox
	- Parallel Computing (if you want faster computation using multicore processing)
1. These additional toolboxes and software are needed for Quadtree/InSAR processing:
	- Image Processing Toolbox
	- Mapping Toolbox
	- Signal Processing Toolbox
	- ```grdwrite2.m``` from [kylebrill @ GitHub](https://github.com/kylebrill/velest-matlab-scripts/blob/master/grdwrite2.m)

## GitHub Etiquette

* Keep file paths sensibly short and understandable
* Where feasible, particularly with example problems, use symbolic links to include redundant and large files (e.g. Green's functions)
* Use only standard (non-greek/non-accented characters for file names and variables)
* Do not use spaces in filenames (CamelCaseIsPreferred).
* *Always Pull then Push!*  This will substantially reduce conflict.
