Version 1.7.10
==============

### NEW FEATURES

apply them in turn

### BUG FIXES

function
* [#928](https://github.com/tidyverse/lubridate/issues/928) On startup lubridate \ 
now resets TZDIR to a proper directory when it is set to non-dir values like \ 
"internal" or "macOS" (a change introduced in R4.0.2)
* [#630](https://github.com/tidyverse/lubridate/issues/630) New parsing \ 
functions `ym()` and `my()`

### BUG FIXES

### BUG FIXES

* [#890](https://github.com/tidyverse/lubridate/issues/890) Correctly compute \ 
year in `quarter(..., with_year = TRUE)`
* [#893](https://github.com/tidyverse/lubridate/issues/893) Fix incorrect \ 
parsing of abbreviated months in locales with trailing dot (regression in \ 
v1.7.8)

Version 1.7.8
=============

### NEW FEATURES

* (breaking) Year and month durations now assume 365.25 days in a year \ 
consistently in conversion and constructors. Particularly `dyears(1) == \ 
years(1)` is now `TRUE`.
* Format and print methods for 0-length objects are more consistent.
* New duration constructor `dmonths()` to complement other duration constructors.
*
* `duration()` constructor now accepts `months` and `years` arguments.
* [#629](https://github.com/tidyverse/lubridate/issues/629) Added \ 
`format_ISO8601()` methods.
* [#672](https://github.com/tidyverse/lubridate/issues/672) Eliminate all \ 
partial argument matches
* [#674](https://github.com/tidyverse/lubridate/issues/674) `as_date()` now \ 
ignores the `tz` argument
* [#675](https://github.com/tidyverse/lubridate/issues/675) `force_tz()`, \ 
`with_tz()`, `tz<-` convert dates to date-times
* [#681](https://github.com/tidyverse/lubridate/issues/681) New constants \ 
`NA_Date_` and `NA_POSIXct_` which parallel built-in primitive constants.
* [#681](https://github.com/tidyverse/lubridate/issues/681) New constructors \ 
`Date()` and `POSIXct()` which parallel built-in primitive constructors.
* [#695](https://github.com/tidyverse/lubridate/issues/695) Durations can now be \ 
compared with numeric vectors.
* [#707](https://github.com/tidyverse/lubridate/issues/707) Constructors return \ 
0-length inputs when called with no arguments
* [#713](https://github.com/tidyverse/lubridate/issues/713) (breaking) \ 
`as_datetime()` always returns a `POSIXct()`
* [#717](https://github.com/tidyverse/lubridate/issues/717) Common generics are \ 
now defined in `generics` dependency package.
* [#719](https://github.com/tidyverse/lubridate/issues/719) Negative Durations \ 
are now displayed with leading `-`.
* [#829](https://github.com/tidyverse/lubridate/issues/829) `%within%` throws \ 
more meaningful messages when applied on unsupported classes
* [#831](https://github.com/tidyverse/lubridate/issues/831) Changing hour, \ 
minute or second of Date object now yields POSIXct.
* [#869](https://github.com/tidyverse/lubridate/issues/869) Propagate NAs to all \ 
internal components of a Period object

### BUG FIXES

* [#682](https://github.com/tidyverse/lubridate/issues/682) Fix quarter \ 
extraction with small `fiscal_start`s.
* [#703](https://github.com/tidyverse/lubridate/issues/703) `leap_year()` works \ 
with objects supported by `year()`.
* [#778](https://github.com/tidyverse/lubridate/issues/778) \ 
`duration()/period()/make_difftime()` work with repeated units
* `c.Period` concatenation doesn't fail with empty components.
* Honor `exact = TRUE` argument in `parse_date_time2`, which was so far ignored.

Version 1.7.4
=============

### NEW FEATURES

* [#658](https://github.com/tidyverse/lubridate/issues/658) `%within%` now \ 
accepts a list of intervals, in which case an instant is checked if it occurs \ 
within any of the supplied intervals.

### CHANGES

* [#661](https://github.com/tidyverse/lubridate/issues/661) Throw error on \ 
invalid multi-unit rounding.
* [#633](https://github.com/tidyverse/lubridate/issues/633) `%%` on intervals \ 
relies on `%m+` arithmetic and doesn't produce NAs when intermediate \ 
computations result in non-existent dates.
* `tz()` always returns "UTC" when `tzone` attribute cannot be inferred.

### BUG FIXES

* [#664](https://github.com/tidyverse/lubridate/issues/664) Fix lookup of period \ 
functions in `as.period`
* [#649](https://github.com/tidyverse/lubridate/issues/664) Fix system timezone \ 
memoization
