Bugs fixed
- Path of `dc2_object_run2.2i_dr6_wfd_v1_with_metacal` fixed. Note: general users should use `dc2_object_run2.2i_dr6_wfd_v1_with_metacal`. (Thanks to combet boutigny heather999.)

We are happy to announce the v1.0.0 release of `GCRCatalogs`. This release includes the (first) complete data set of the DC2 (Run 2.2i) DR6 WFD, and several other new catalogs.

New Catalogs for DC2 (Run 2.2i) DR6 WFD

- `dc2_object_run2.2i_dr6_wfd`: Object catalog of DC2 (Run 2.2i) DR6 WFD
- `dc2_object_run2.2i_dr6_wfd_with_metacal`: Object catalog + metacal of DC2 (Run 2.2i) DR6 WFD

Thanks to the whole DC2 team for delivering these data products! Photo-z and matched catalogs for `dc2_object_run2.2i_dr6_wfd` will be made available soon.

Additional new catalogs

- `dc2_object_run2.2i_dr6c_matched_addon`: CosmoDC2-matched object catalog for the DR6c (a preview of DR6 WFD). Thanks to fjaviersanchez.
- `photoz_SKRF_v1_for_cosmoDC2_v1.1.4_small`: Random-forest PZ for cosmoDC2 small, generated by Olivia/Markus. Thanks to sschmidt23 for adding this.


This release will be installed on DESC environments on NERSC shortly (thanks to heather999). Note that you can also use `desc-python-bleed` to access the master branch (build every Monday).

This release (v0.19.0) of `GCRCatalogs` includes several new catalogs, including new ML-based photo-z for cosmoDC2, a pre release of Run 2.2i DR6 catalogs, and truth catalogs for Run 2.2i.

New Catalogs

Photo-z catalogs for cosmoDC2

A ML-based photo-z (using flexzboost) has been added (listed below), thanks to sschmidt23. In addition, the performance of the photoz composite catalogs has been improved.

- `cosmoDC2_v1.1.4_image_with_photozs_flexzboost_v1`
- `cosmoDC2_v1.1.4_small_with_photozs_flexzboost_v1`

Run 2.2i DR6

Thanks to johannct and the whole DC2 team. *Note: DR6 corresponds to the first 5 years of data.*

Run 2.2i DR6c: the latest pre-release of DR6

- `dc2_object_run2.2i_dr6c`: 165 tracts (in WFD region) of DR6 object catalog
- `dc2_object_run2.2i_dr6c_with_metacal`: 159 tracts (in WFD region) of DR6 object+metacal catalog

Run 2.2i DR6a: an earlier pre-release of DR6

- `dc2_object_run2.2i_dr6a`: 78 tracts (in WFD region) of DR6 object catalog
- `dc2_object_run2.2i_dr6a_with_metacal`: 63 tracts (in WFD region) of DR6 object+metacal catalog
- `dc2_object_run2.2i_dr6a_with_photoz`: 78 tracts (in WFD region) of DR6 object catalog with photo-z
- `dc2_object_run2.2i_dr6a_matched_addon`: 78 tracts (in WFD region) of DR6 object catalog with matched truth info

*Note: `dc2_object_run2.2i_dr6` has been temporarily removed to avoid confusion. It will be added back when the full DR6 data set is ready. For now, use `_dr6a` or Use `_dr6c` based on your need.

This release contains a bug fix to correct the definition of `psf_fwhm_{band}` in object catalogs (thanks to wmwv).

This release (v0.18.0) contains an important new feature (deprecation warning), and the addition of several new catalogs, including the Run 2.2i DR6 Object Catalog.

New Feature

We start to add deprecation warnings to some older catalogs that we recommend users to stop using and switch to newer alternatives. The deprecated catalogs can still be loaded and used, but a deprecation warning will show up at load time. If you find your analysis relies on a specific version of catalog that have been deprecated, please [open an issue](https://github.com/LSSTDESC/gcr-catalogs/issues).

New Catalogs

- `dc2_object_run2.2i_dr6`: 78 tracts of Run 2.2i DR6 is now available. (Thanks to johannct and the DC2 Team!)
- `cosmoDC2_v1.1.4_redmapper_v0.5.7`: An updated RedMapper catalog for cosmoDC2. (Thanks to erykoff)

Catalog Changes

- Several photo-z catalogs have been renamed for a consistent naming scheme. See [this Confluence page](https://confluence.slac.stanford.edu/x/uwUwE) for the list of the new set of photo-z catalog names. We preserve backward compatibility for several frequently used photo-z catalogs (i.e., the old catalog names can still be used, but users will see a deprecation warning). (Thanks to sschmidt23)
