Note: This is a Substantial Update.
This change will allow users to extend the Target Model with their own fields. It is backwards compatible in that you should see no difference in your current code, but once you have upgraded to tomtoolkit-2.19.0 and run `manage.py migrate` you will not be able to easily revert back to prior versions of the TOM Toolkit. We recommend backing up your DB before performing any complex migrations. If you have any questions or need any assistance, please don't hesitate to contact us on the TOM Toolkit slack workspace or at tomtoolkit-maintainerslco.global.
Extended Target Model:
This change allows users to provide their own django model containing custom Target Fields. This is meant to complement or replace the `Target Extras`. A Management command is provided for converting your Target Extras into custom Fields once they are created, and a full description of this capability is given in the [docs](https://tom-toolkit.readthedocs.io/en/latest/targets/target_fields.html)
Enhanced Match Manager:
We also include with this release, an improved match manager. This tool makes checking for related or identical targets easier, and now includes a built in cone-search option. The most significant change to the earlier match manager is that this one should be substantially easier to extend and modify by users. A complete description of this new feature is included in the [docs](https://tom-toolkit.readthedocs.io/en/latest/targets/target_matcher.html).
