Changes in version 0.4.0                        

  - The AZMet API was updated to return HTTP error codes for bad
    requests or server errors and these are now displayed to users.
  - Updated az_add_units() to include columns returned by az_15min(),
    az_lw15min(), and az_lwdaily()
  - Added Duncan station ("az46") to station information
  - tibbles produced by az_*() functions now have the "labels" attribute
    set on columns. This is used for things like tooltips in the
    Positron data viewer and default axis labels for ggplot2 plots
    (https://tidyverse.org/blog/2025/09/ggplot2-4-0-0/#labels)
  - Updated package to access data from 2020
  - Added end_date variable with value NA to azmet-station-info.csv
  - Reformatted start_date variable to work with data download functions
  - Added Elgin station ("az47") to station information
  - Added start_date and status variables to azmet-station-info.csv
  - Added Chino Valley station ("az45") to station information
  - Added Test station ("az99") to station information

  - Added function az_lwdaily() for downloading daily leaf wetness data,
    which now are available via the API
  - Added function az_lw15min() for downloading 15-minute (a.k.a.
    "real-time") leaf wetness data, which now are available via the API
  - Added function az_15min() for downloading 15-minute (a.k.a.
    "real-time") data, which now are available via the API

                        Changes in version 0.3.0                        

  - az_hourly() now accepts dates for start_date_time and end_date_time
  - Improved messages regarding what date/time ranges are being queried
    and returned by data retrieval functions.
  - az_hourly() now returns data from the previous hour when
    start_date_time and end_date_time are not supplied rather than
    returning the previous day of hourly data.
  - azmet is now much more verbose, printing messages about which data
    are requested and which data are returned.
  - Added an option "azmet.print_api_call" which, when set to TRUE
    prints the HTTP request sent to the API—for debugging purposes.
  - Fixed a bug that caused an error when data was requested from all
    stations but some stations didn't have data for all variables.
  - Requests for data before January 1, 2021 now error, since these data
    are not on the AZMet API (yet).

                        Changes in version 0.2.1                        

  - az_daily() and az_hourly() now print a warning if there is any
    missing data for the combination of dates and stations requested
  - Transferred maintenance of package to Jeremy Weiss
  - Timestamp for hourly and daily maximum two-minute sustained wind
    speeds, wind_2min_timestamp now appears in downloaded data
  - Variable type for hourly and daily wind_2min_timestamp now is
    date-time instead of character with correct time zone, tzone =
    "America/Phoenix"
  - Values for hourly date_datetime variable now have tzone =
    "America/Phoenix" assigned
  - The station_info dataset now includes elevation

                        Changes in version 0.2.0                        

  - azmetr now uses the httr2 package instead of httr for API requests.
    This change allowed for easier rate limiting
  - There is now a rate limit of 4 requests per second to the API. This
    shouldn't cause noticeable slowdowns except when using the
    station_id argument maybe
  - az_add_units() now adds units to new wind_2min_* variables recently
    added to the API

                        Changes in version 0.1.0                        

  - functions now check if supplied station_id is valid and an active
    station before querying the API
  - added station_info dataset with station names, IDs, and location.
  - az_daily() and az_hourly() convert values like -999, -9999, etc.
    into NAs
  - functions now return a 0x0 tibble when no data is returned by the
    API
  - changed internal use of base R pipe (|>) to magrittr pipe (%>%)
    instead of requiring R 4.1 or later
  - exports magrittr pipe (%>%) so it can be used when loading only
    azmetr
  - You can now supply POSIXct or Date values to start_date and end_date
    arguments in addition to character ISO representations of date (e.g.
    YYYY-MM-DD or YYYY/MM/DD). You can supply POSIXct to start_date_time
    and end_date_time. Additionally, you can use character with at least
    (but potentially more) precision to the hour. (e.g., YYYY-MM-DD
    HH:MM:SS now works and gets rounded down to the nearest hour).
  - added vignettes
  - fixed a bug where the wrong units were added to variables ending in
    _mps by az_add_units()

                     Changes in version 0.0.0.9000                      

  - Functions for accessing hourly (az_hourly()) and daily (az_daily())
    weather, and cumulative heat units / ETO (az_heat()) added.
  - Added a NEWS.md file to track changes to the package.
