Changes in version 2.1.5 (2024-11-20)                  

  - Minor fixes to tests due to changes in R-base
  - Export increment() utility function

                 Changes in version 2.1.4 (2022-10-17)                  

  - vectors of length 1 are now recycled when adding or subtracting
    date_xx objects, e.g. date_yq(2019, 1) + 1:4 is now possible (#5).
  - qy can now handle inputs without sepperator between quarter and year
    (e.g. myfile42019)
  - as.POSIXlt.date_xx() and as.POSIXct.date_xx() now set UTC timezone
    by default (for compatibility with as.POSIXct.Date() changes in
    latest R version)

                 Changes in version 2.1.3 (2020-02-06)                  

  - Correct a small error in the documentation of date_xx_arithmetic
    that triggers a CRAN Warning since the fixing of
    https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16223>

                 Changes in version 2.1.2 (2020-01-07)                  

  - Updated all scale_date_*() functions for compatibility with ggplot2
    >= 3.2.2

                 Changes in version 2.1.1 (2019-12-02)                  

  - format.date_xx() now used %V for isoweeks instead of %W to prevent
    confusion with strftime(), where %W denotes UK-weeks. Using %W has
    been deprecated and will be removed in future versions.
  - added yq(), qy(), ym(), my() "smart" parsers similar to
    lubridate::dmy() & co.
  - as_date_ym() and as_date_yw() now handle input vectors that contain
    NAs (as as_date_yq() already did)
  - last_of_quarter() no longer depends on the lubridate package

                 Changes in version 2.1.0 (2019-01-03)                  

  - added ggplot2 scales for dint data types
  - added predicates to check whether dates correspond to the boundaries
    of years or quarters (is_quarter_bounds(), is_year_bounds(),
    is_first_of_quarter(), etc...)
  - export methods for unique and summary that were introduced in the
    last version but mistakenly not exported
  - One can now subtract two date_xx of the same subclass from each
    other (the result is an integer)
  - added as_yearmon() and as_yearqtr() for converting to zoo S3 classes
  - Removed functions that were deprecated with dint 2.0.0
  - added Sys.date_yq(), Sys.date_ym() and Sys.date_yw() to get the
    current quarter, month or isoweek.
  - lots of small fixes

                 Changes in version 2.0.0 (2018-09-29)                  

  - breaking: formatting date_xx objects now uses placeholders similar
    to base::strptime() (e.g %Y, %m, %q, etc...) instead of presets. The
    new implementation is also noticeably faster than the old.
  - breaking: all first_day_of_*() and format_date_y*() functions now
    have shorter names: first_of_*() and format_y*(). The original names
    will still work until the next release but give a deprecation
    warning.
  - Added support for c(), min(), max(), range()
  - You can now directly supply a numeric year to first_of_year() and
    last_of_year() (e.g. first_of_year(2018))
  - added date_yw for storing isoweeks and modified existing functions
    to accommodate for them.
  - added [ method for date_xx objects that preserves class attribute
    when subsetting
  - %y+% / %y-% can add/subtract years from date_xx objects
  - added the predicates, is_first_of_quarter(), is_last_of_quarter(),
    and is_quarter_bounds().
  - seq() methods now support a by argument

                 Changes in version 1.0.0 (2018-08-13)                  

  - First stable version
