                 Changes in version 1.2.0 (2026-08-21)                  

  - Minor changes:
    
      - When the package tries to download multiples but fails with a
        few ones, the package now only try to download again the files
        that failed in the first attempt.
      - The function read_aircrafts() now throws an error, as it has
        been deprecated in favor of read_aircraft() simply to fix a typo
        in the function name. The behavior and outputs are identical.
      - read_airfares() and read_flights() now cache the list of
        dates/files available from ANAC to a session-scoped temp file,
        governed by the existing cache parameter. This avoids
        re-scraping ANAC's website on every single call within the same
        R session.
      - Files are now downloaded using httr2::req_perform_parallel(),
        replacing curl::multi_download().

  - Bug fixes:
    
      - Fixed error in reading data from ANAC website. Fixed #52 and
        #51.
      - Fixed the select parameter in read_airfares(), which was
        silently ignored and had no effect on the columns returned. It
        now behaves the same way as select in read_flights().
      - Fixed get_airfares_dates_available() (used internally by
        read_airfares()) to retry requests to ANAC that fail transiently
        (timeouts, connection errors, HTTP 429/503) instead of silently
        dropping the affected year and returning an incomplete list of
        available dates.
      - Fixed get_airfares_dates_available() and latest_airfares_date()
        to fail cleanly with NULL when ANAC can't be reached, instead of
        occasionally producing a nonsensical "data available between Inf
        and -Inf" error, or -Inf as a date.
      - Replaced a brittle hardcoded filename-length check (nchar == 55)
        used to filter valid international airfare files listed by ANAC
        with an explicit filename-pattern check, and added the
        equivalent check to the domestic airfare listing (which
        previously had no filter at all). This guards against malformed,
        duplicate, or misplaced files that ANAC occasionally publishes
        (e.g. typo'd names, files uploaded to the wrong year, re-uploads
        with (1) appended) corrupting the list of available dates.

                 Changes in version 1.1.1 (2025-07-24)                  

  - The previous version of {flightsbr} was temporarily taken down from
    CRAN because one of its dependencies (the {parzer} package) was
    removed from CRAN on July 1st 2025. This update of flightsbr v1.1.1
    is simply intended to put the package back on CRAN.

                 Changes in version 1.1.0 (2025-05-19)                  

  - Major changes:
    
      - The default of all read_ functions now is to download data from
        the latest date available.
      - The function read_aircrafts() is now deprecated in favor of
        read_aircraft() simply to fix a typo in the function name. The
        behavior and outputs are identical. Closes #45

  - CRAN policy:
    
      - updaed DESCRIPTION file removing 'NeedsCompilation'

                 Changes in version 1.0.0 (2024-10-22)                  

  - Breaking changes:
    
      - The names of all columns in the data outputs are now cleanned
        with {janitor}
      - Function read_airports() now downloads v2 version of public
        airports data. Closes #41

  - Major changes:
    
      - Function read_airfares() is working again. Closes #30. The
        prices of air tickets are now returned as numeric.
      - Function read_flights() with fixed decimal values in numeric
        columns. Closes #43
      - Function read_airports() with fixed numeric values for
        "altitude" column. Closes #42

  - Minor changes:
    
      - Internally check of the consistency of date inputs. The date
        input must be consistent in either a 6-digit format yyyymm OR
        a 4-digit format yyyy.
      - New support function latest_airfares_date()
      - Fix error that stopped reading aircraft data read_aircraft() for
        multiple months when the number of collums differed across
        months. Fixed using data.table::rbindlist(fill = TRUE)

                 Changes in version 0.5.0 (2024-09-18)                  

  - Major changes:
    
      - Fixed ANAC's broken link of public airports
      - Functions read_flights(), read_airport_movements(), and
        read_aircraft() now accept vectors of dates like
        c(202201, 202301) or c(2022, 2024)
      - Functions read_airports() and read_aircraft() now has a cache
        parameter.
      - The package is now significantly faster because it is using
        curl::multi_download() to download files in parallel. This
        brings the advantage that the package now automatically detects
        whether the data file has been updated and should be downloaded
        again.

  - Minor changes:
    
      - Removed dependency on the {httr} package
      - Streamlined functions to simplify package maintenance and
        improve performance
      - Using {fs} to manage file paths and {archive} to unzip files
      - Reorganization of internal functions to simplify package
        maintenance

                 Changes in version 0.4.1 (2024-04-23)                  

  - Minor changes:
      - The read_flights() function now uses fread(encoding = 'Latin-1')
        internally to avoid issues with encoding. Closed #35.
      - The function get_airport_movement_dates_available() does not
        throw warnings of NA values anymore.
      - The read_aircraft() function now used fread(skip = 1) internally
        to read column names correctly.

                 Changes in version 0.4.0 (2023-12-04)                  

  - Major changes:
    
      - The functions read_flights() and read_airport_movements() now
        have a new parameter cache, which indicates whether the function
        should read cached data downloaded previously. Defaults to TRUE.
        Closed #31.
      - The function read_aircraft() now has a date parameter, which
        allows one to download the data on aircraft registered at ANAC
        at particular years/months. Closed #33.

  - Minor changes:
    
      - All functions now return numeric columns with numeric class.
        Closed #32.

        #26.
      - Fixed code to read a few dates that were not caught in
        get_airfares_dates_available() because of ".CSV" in ANAC url.
        Closed #27.
      - Fixed code to use get_airport_movement_dates_available()

                 Changes in version 0.2.1 (2022-11-27)

  - Minor changes:
    
      - The data downloaded in read_flights() and
        read_airport_movements() are now cached in temp dir. Closed #20.
      - All columns are now returned with class character. This fixes a
        bug in the read_airport_movements() function. Closed #20.

                 Changes in version 0.1.2 (2022-03-18)

  - Bug fixes:
      - functions read_flights() and read_airport_movements() no longer

        the package. Closed #17.
      - read_ functions now try to download for a 2nd time if the 1st

        instability of ANAC data links. Closed #18.
      - Using a simpler / slightly faster version of latlon_to_numeric()
        with suppressed warnings.
      - Update package citation, adding OSF preprint DOI.

        latest flights data available. Closed #13.
