Changes in version 1.0.2 (2021-01-04)                  

CRAN MAINTENANCE

  - A test that was failing due to an incorrect assumption that the
    first day of the year would always fall on the first week of the
    year was fixed (see https://github.com/reconhub/aweek/issues/35 for
    details). (#36, @zkamvar).

MISC

  - Continuous integration has been migrated from Travis-CI + AppVeyor
    to GitHub actions.

                 Changes in version 1.0.1 (2020-04-29)                  

CRAN MAINTENANCE

  - as.POSIXlt() now converts NULL to an empty POSIXlt object, so a test
    that was previously checking for an error failed. That test has been
    fixed (#33, @zkamvar)

                 Changes in version 1.0.0 (2019-06-11)                  

NEW FUNCTIONS

  - change_week_start() allows the user to change the week_start
    attribute of an aweek object, adjusting the weeks to match the new
    attribute accordingly.
  - get_aweek() can generate aweek objects from a vector of week
    numbers. It has the ability to take into account different week
    start times.
  - get_date() is similar to get_aweek(), but returns dates instead.
  - as.aweek() allows users to create aweek object directly from
    characters with validation. It also allows for dates by passing to
    date2week().
  - as.data.frame.aweek() is a new function that allows aweek objects to
    be directly incorporated into data frames.
  - as.list.aweek() will now preserve the aweek structure in lists
  - trunc.aweek() will truncate the day to the first day of the week.
  - rep.aweek() allows repeating aweek characters.
  - factor_aweek() allows the user to create aggregated aweek objects on
    the fly.

BREAKING CHANGES

There are a couple of breaking changes coming to aweek that will improve
stability by removing unclear coercion methods (see
https://github.com/reconhub/aweek/issues/20).

  - It is no longer possible to combine aweek objects if they do not
    share the same week_start attribute. This will result in an error
    informing the user to adjust the week_start attribute with the
    change_week_start() function.
  - Factors will no longer coerce factors when combining aweek objects.
  - Using date2week() with factor = TRUE and floor_day = FALSE now
    throws an error instead of a warning (as prophesized in #13).

DOCUMENTATION

  - The vignette has been updated to include an explanation of the
    underlying week calculation from date.
  - The aweek class documentation has been updated to detail the
    different elements of the object and the calculations.
  - Package documentation package?aweek has been added for an
    introduction.

BUG FIX

  - conversions will now retain the names of the object.

MISC

  - More checks that weekdays and weeks are within the correct bounds
    have been added.
  - as.Date.aweek has been simplified to no longer rely on regex since
    the aweek class is standard.
  - The internal get_wday() has been vastly simplified with improved
    speed.

                        Changes in version 0.3.0                        

  - The week_start argument now defaults to the global option
    aweek.week_start, which will be a number from 1 to 7, representing
    the days of the week in the ISO 8601 standard.
  - set_week_start() is a convenience allowing the user to set the
    default aweek.week_start option via integer or character input.
  - get_week_start() is a wrapper for getOption("aweek.week_start", 1L)
    and attr(w, "week_start") for aweek objects.

                 Changes in version 0.2.2 (2019-04-26)                  

  - Simplified conversion to factors.
  - Using factor = TRUE without floor_day = TRUE will now issue a
    message indicating that this is deprecated in future versions of
    aweek (see #13).

                        Changes in version 0.2.1                        

  - Fix bug where NAs threw errors in the dates (found: @aspina7, #12)

  - as.data.frame.aweek() will now convert aweek objects to columns of
    data frames without losing class or attributes

  - The introduction vignette has been updated to reflect this change.

                 Changes in version 0.2.0 (2019-03-08)                  

  - Subsetting and concatenating methods added to the aweek class (see
    #1)
  - Documentation divided into smaller chunks
  - as.POSIXlt() bug where tz was not being passed was fixed.
  - date2week(): an error is now issued if users specify non-ISO 8601
    dates OR don't specify a format option. (found: @scottyaz, #2)
  - Best practices added to vignette
  - Fix test that would fail every seven days on CRAN

                 Changes in version 0.1.0 (2019-03-06)                  

  - First official release of aweek on CRAN

                     Changes in version 0.0.5.9000                      

  - date2week() and week2date() can now take days represented as
    characters in the current or English locale.

                     Changes in version 0.0.4.9000                      

  - date2week() gains a factor argument, which will automatically
    compute the levels within the date range.

                     Changes in version 0.0.3.9000                      

  - date2week() now properly accounts for dates in December that occur
    in the first week of the next year.

                     Changes in version 0.0.2.9000                      

  - floor_day now truncates the week instead changing the last digit
    to 1 for aesthetics. (Thanks to @aspina7 for the suggestion) q
    print.aweek() now displays the day of the week in the current
    locale.

                     Changes in version 0.0.1.9000                      

  - First version of package
  - date2week() converts dates to aweek objects
  - week2date() converts aweek objects or character strings to dates
  - as.Date() does the same thing as above
  - as.POSIXlt() as well
  - as.character() will unclass the aweek object
  - Added a NEWS.md file to track changes to the package.
