tidycensus 1.0

• Support for the ACS Migration Flows API is available in a new function, get_flows(). Browse the supporting documentation for information on how to analyze and map migration flows data in tidycensus.
• The shift_geo argument is deprecated in favor of using the new tigris::shift_geometry() function. This allows for shifting of geometries for any geography in national mapping projects.
• Various bug fixes and performance improvements; browse the GitHub issues for a complete listing.

tidycensus 0.11.4

• Added support for the 2015-2019 5-year ACS PUMS data in get_pums(). Updated variable definitions are found in the data object pums_variables.
• The default year in get_pums() is updated to 2019.
• For 2015-2019 ACS aggregate data, get_acs() now supports the state parameter for zip code tabulation areas (ZCTAs) to allow subsetting by state.
• Various bug fixes and internal improvements; browse the GitHub issues for a complete listing.
• Added a NEWS.md file to track changes to the package.

tidycensus 0.11

• get_acs() now defaults to year = 2019, meaning that 2015-2019 5-year estimates and 2019 1-year estimates are retrieved if no year is specified.
• get_estimates() now also defaults to year = 2019.
• tidycensus can once again access the 2000 Summary File 3 in get_decennial() as the Census Bureau has restored its API endpoint.
• Various bug fixes and internal improvements; browse the GitHub issues for a complete listing.

tidycensus 0.10.2

• tidycensus now includes functionality to download and analyze data from the American Community Survey Public Use Microdata Series (PUMS) datasets. Read through the corresponding documentation to learn how to use these features.
• tidycensus cannot access 1990 data or 2000 Summary File 3 data due to the removal of these API endpoints by the Census Bureau. When new endpoints for these years are added, tidycensus will support them again in a future release.

tidycensus 0.9.9.2

• geometry = TRUE now works for all geographies currently available in tidycensus.
  
• get_acs() can now support the ACS Supplemental Estimates API.

tidycensus 0.9.5

• get_acs() now defaults to the 2014-2018 five-year American Community Survey estimates, or the 2018 1-year estimates if users set survey = "acs1".
• Various improvements and bug fixes (largely thanks to Matt Herman’s contributions).

tidycensus 0.8.1

• tidycensus now includes support for the Census Bureau Population Estimates API. Please see https://walkerke.github.io/tidycensus/articles/other-datasets.html for examples of how to use these new features.

• Important internal changes to ensure that tidycensus continues to work with upcoming changes to Census API endpoints.

• Several internal improvements and bug fixes. Please see the closed issues at https://github.com/walkerke/tidycensus/issues for a list.

tidycensus 0.4.6

• Bug fixed that was causing GEOIDs for some states to be converted to NA on certain Linux platforms

• A new parameter, shift_geo, allows tidycensus users to get US state and county geometry originally obtained with the albersusa R package with Alaska and Hawaii shifted and re-scaled for better cartographic display of the entire US.
