Tidycensus

* Defaults for `get_acs()` and `get_pums()` updated to 2023 following full release of the 2023 ACS datasets.

* Support added in `get_estimates()` for the 2023 PEP datasets. A new argument, `vintage`, allows users to request data by vintage and then by `year` within that vintage for post-2020 PEP datasets.

* Default year in `get_acs()` and `get_pums()` updated to 2022 following full release of the 2022 ACS datasets.
* Geometry support for the 118th Congress in `get_decennial()` when `sumfile = "cd118"` is used, and in `get_acs()`
* Various bug fixes and performance improvements.

* Support added for the new Detailed DHC-A file, which includes the ability to query for detailed population groups. This functionality is now enabled for Summary Files 2 and 4 in past years as well with the `pop_group` argument.
* Full geometry support enabled for the 2022 1-year American Community Survey.
* Various bug fixes and performance improvements, including the pesky 'Error in UseMethod("gather") no applicable method for 'gather' applied to an object of class "character"' problem.

* `get_estimates()` now supports the newer Population Estimates Program (PEP) datasets not found on the Census API. Please review the package documentation at https://walker-data.com/tidycensus/articles/other-datasets.html for examples of how to use the new datasets, which differ slightly from older versions.
* Decennial Census data for island areas and some historical decennial Census files (for 2000) are now available. To see a full list of decennial Census datasets available in tidycensus, use the `summary_files()` function.

* `get_decennial()` has been updated to accommodate the new Demographic and Housing Characteristics and Demographic Profile summary files. Use `sumfile = "dhc"` for the DHC file, and `sumfile = "dp"` for the DP file.
* The default year in `get_decennial()` is now 2020. This may be a breaking change for some legacy code that omits the year, so be sure to update scripts to hard-code the year for years earlier than 2020.
* `sumfile = "pl"` is the default for `get_decennial()` and will remain so to avoid existing code breakages. Please note that variable IDs are replicated across the PL and DHC files, but may represent different topics.
