20.0.1

*(August 4, 2020)*

Rerelease to fix packaging metadata around conditional requirements.
See [issue 133](https://github.com/python-hyper/hyperlink/issues/133)
for more details.

20.0.0

*(August 3, 2020)*

* CPython 3.7 and 3.8 and PyPy3 added to test matrix
* Hyperlink now has type hints and they are now exported per
[PEP 561](https://www.python.org/dev/peps/pep-0561/).
* Several bugs related to hidden state were fixed, making it so that all data
on a `URL` object (including `rooted` and `uses_netloc`) is reflected by and
consistent with its textual representation.
This does mean that sometimes these constructor arguments are ignored, if it
would create invalid or unparseable URL text.

19.0.0

*(April 7, 2019)*

A query parameter-centric release, with two enhancements:

* "equals sign" characters in query parameter values are no longer
escaped. (see
[39](https://github.com/python-hyper/hyperlink/pull/39))
* `URL.remove()` now accepts *value* and *limit* parameters, allowing
for removal of specific name-value pairs, as well as limiting the
number of removals.
(See [71](https://github.com/python-hyper/hyperlink/pull/71))

18.0.0

*(February 25, 2018)*

Maybe the biggest release since the original. Big thanks to glyph,
wsanchez, Julian, wbolster, and of course, markrwilliams, for all
the reports, reviews, and other contributions.

* When passed to `str()` URLs now stringify to usable URL
strings. (See 49)
* Switched off of Python's built-in IDNA facilities to using the
[idna](https://pypi.python.org/pypi/idna) package. Not only is it
much more modern, it's also much more strict and correct in its
output. (See 19 and 56)
* Added new `DecodedURL` type with almost-identical API to the normal
`URL`, except that it automatically handles reserved characters in
argument values passed to its methods. (See 6, 11, 44)
* Added top-level `parse()` convenience function that now represents
the main entrypoint to hyperlink.
* Accept dictionaries as ‘query=’ arguments, in addition to
sequences of tuples (see 50)
* `URL.child()` will no longer fail when child gets no segments (42 and 43)
* `URL.normalize()` now supports encoding stray/unmatched `%` characters
in character-encoded fields (userinfo, path, query string, fragment)
(see 61, 62)

17.3.1

*(August 19, 2017)*

* Add `URL.normalize()` method, which applies five normalizations from
RFC 3986 (sections 2.3, 2.1, 3.2.2, 6.2.2.3, 6.2.3). See [the docs](http://hyperlink.readthedocs.io/en/latest/api.htmlhyperlink.URL.normalize)
for more details.
* Enable `URL.click()` to accept a URL object as a target.

17.3.0

*(July 18, 2017)*

Fixed a couple major decoding issues and simplified the URL API.

* limit types accepted by `URL.from_text()` to just text (str on py3,
unicode on py2), see 20
* fix percent decoding issues surrounding multiple calls to
`URL.to_iri()` (see 16)
* remove the `socket`-inspired `family` argument from `URL`'s APIs. It
was never consistently implemented and leaked slightly more problems
than it solved.
* Improve authority parsing (see 26)
* include LICENSE, README, docs, and other resources in the package

17.2.1

*(June 18, 2017)*

A small bugfix release after yesterday's big changes. This patch
version simply reverts an exception message for parameters expecting
strings on Python 3, returning to compliance with Twisted's test
suite.

17.2.0

*(June 17, 2017)*

Fixed a great round of issues based on the amazing community review
(wsanchez and jvanasco) after our first listserv announcement and
[PyConWeb talk](https://www.youtube.com/watch?v=EIkmADO-r10).

* Add checking for invalid unescaped delimiters in parameters to the
`URL` constructor. No more slashes and question marks allowed in
path segments themselves.
* More robust support for IDNA decoding on "narrow"/UCS-2 Python
builds (e.g., Mac's built-in Python).
* Correctly encode colons in the first segment of relative paths for
URLs with no scheme set.
* Make URLs with empty paths compare as equal (`http://example.com`
vs. `http://example.com/`) per RFC 3986. If you need the stricter
check, you can check the attributes directly or compare the strings.
* Automatically escape the arguments to `.child()` and `.sibling()`
* Fix some IPv6 and port parsing corner cases.

17.1.1

* Python 2.6 support
* Added LICENSE
* Automated CI and code coverage
* When a host and a query string are present, empty paths are now
rendered as a single slash. This is slightly more in line with RFC
3986 section 6.2.3, but might need to go further and use an empty
slash whenever the authority is present. This also better replicates
Twisted URL's old behavior.

17.1.0

* Correct encoding for username/password part of URL (userinfo)
* Dot segments are resolved on empty URL.click
* Many, many more schemes and default ports
* Faster percent-encoding with segment-specific functions
* Better detection and inference of scheme netloc usage (the presence
of `//` in URLs)
* IPv6 support with IP literal validation
* Faster, regex-based parsing
* URLParseError type for errors while parsing URLs
* URL is now hashable, so feel free to use URLs as keys in dicts
* Improved error on invalid scheme, directing users to URL.from_text
in the event that they used the wrong constructor
* PEP8-compatible API, with full, transparent backwards compatibility
for Twisted APIs, guaranteed.
* Extensive docstring expansion.

Pre-17.0.0

* Lots of good features! Used to be called twisted.python.url
