# deeptime 2.3.0

This new minor version of deeptime includes a small number of new features and some minor housekeeping.

New features:

* The `pos` argument for `coord_geo()` is now recycled when `dat` is a list, removing the need for repeated `pos` values when adding multiple time scales to the same side (#86)
* Added built-in dataset `fgdc_names` which includes FGDC pattern codes and verbatim names for named patterns
* Added `fgdc_dict()` which can be used to generate a labeling dictionary for FGDC pattern codes (#79)
* Added an optional theme element (`deeptime.scale.background`) to customize the background of the time scale area in `coord_geo()` (#87)

Deprecation:

* Removed `getScaleData()`.
* Advanced the deprecation of `gggeo_scale()`. This function has been fully deprecated from deeptime in favor of `coord_geo()`.

Miscellaneous:

* Updated citation information for the package (#89)
* Updated package logo to reflect the recent inclusion of patterns (#90)
* Added contribution docs (#91)

# deeptime 2.2.0

This new minor version of deeptime introduces several new features and bug fixes. It also is compatible with version 4 of ggplot2.

New features:

* Added `geom_text_phylo()` for adding node/tip labels to phylogenies when using `coord_geo_radial()`
* Updated built-in timescales to 2024/12 version of GTS
* Removed the defaults for the `colors` argument in `facet_grid_color()`, `facet_wrap_color()`, `facet_nested_color()`, and `facet_nested_wrap_color()`
  * Added `facet_grid_geo()`, `facet_wrap_geo()`, `facet_nested_geo()`, and `facet_nested_wrap_geo()` which now serve as aliases for these functions with their original defaults (#81)
* Added legends to the examples in the "Plotting geological/stratigraphical patterns" vignette (#78)
* Added facetting examples to the "Plotting temporal data" vignette (#80)

Deprecation:

* Advanced the deprecation of `coord_geo_polar()`. Use of this function will result in a warning. This function will be removed in a future version of deeptime.
* Advanced the deprecation of `getScaleData()`. This function has been fully deprecated from deeptime in favor of `get_scale_data()`.

Bug fixes:

* Fixed `gtable_frame2()` and `ggarrange2()` for plots that use `theme_void()` (#74)
* Fixed `disparity_through_time()` for rare edge cases (#71)
* Updated `GeomPointsRange` to use the aesthetic defaults from `ggplot2::GeomPointrange`
* Updated `GeomTextPhylo` to use the aesthetic defaults from `ggplot2::GeomText`

# deeptime 2.1.0

This new minor version of deeptime introduces several new features and bug fixes.

New features:

* Added default label color values to all built-in data as a new `lab_color` column
  * The label colors are either white or black, whichever has better contrast with the background color based on [recommendations by the International Telecommunication Union](https://www.itu.int/rec/R-REC-BT.601-7-201103-I/en)
* `get_scale_data()` now returns label colors (as above) for Macrostrat timescales
* Varying strip label colors can now be set with the `lab_colors` argument in `facet_wrap_color()` and `facet_grid_color()` (#68)
  * By default, the strip label colors are set to white or black (as above)
* Added `facet_nested_color()` and `facet_nested_wrap_color()` to plot nested faceted plots with colored strips (#55)
* `get_scale_data()` documentation now lists the available Macrostrat timescales (#69)
* `get_scale_data()` now supports partial matching to Macrostrat timescales (e.g., `get_scale_data("mammal")` will retrieve the "North American land mammal ages" timescale)

Notable changes:

* The FGDC pattern data added in deeptime 2.0.0 has been moved to a new data R package called `deeptimedata` to reduce the size of the deeptime package and the footprint of future deeptime updates

Bug fixes:

* Fixed importing some functions from `ggplot2` for `coord_geo_radial()` and `coord_geo_polar()`

# deeptime 2.0.0
__deeptime now requires ggplot2 version 3.5.0 or higher__.\

* Added functions to use FGDC/USGS patterns as ggplot2 fills or with the `ggpattern` package (see new vignette) (#52)
* Added the `true_colors` option to `get_scale_data()`, which, when set to `FALSE`, can be used to retrieve the custom Macrostrat colors that were previously in the built-in datasets (#62)
* Updated built-in timescales to 2023/06 version of GTS
* Added option to `coord_geo()` to abbreviate interval labels based on only the intervals that are being plotted (#64)

Notable changes:

* The `phytools` package is no longer required to install `deeptime` but is required to use the `geom_phylomorpho()` function

* The `gggeo_scale_old()` function has been fully deprecated
