Changelog

1.5.0 (2020-10-02)

Feature: Improve performance by using global imports. (#38 by @clue)
Improve API documentation and add support / sponsorship info. (#30 by @clue and #35 by @SimonFrings)
Improve test suite and add .gitattributes to exclude dev files from exports. Prepare PHP 8 support, update to PHPUnit 9 and simplify test matrix. (#32 and #37 by @clue and #34 and #36 by @SimonFrings)

Fix: Check if the function is declared before declaring it. (#23 by @Niko9911)
Improve test suite to also test against PHP 7.2 and add test for base64 encoding and decoding filters. (#22 by @arubacao and #25 by @Nyholm and @clue)

Feature / Fix: The fun() function does not pass filter parameter null to underlying stream_filter_append() by default (#15 by @Nyholm)

Certain filters (such as convert.quoted-printable-encode) do not accept a filter parameter at all. If no explicit filter parameter is given, we no longer pass a default null value.
```
$encode = Filter\fun('convert.quoted-printable-encode');
assert('t=C3=A4st' === $encode('täst'));
```
Add examples and improve documentation (#13 and #20 by @clue and #18 by @Nyholm)
Improve test suite by adding PHPUnit to require-dev, fix HHVM build for now again and ignore future HHVM build errors, lock Travis distro so new future defaults will not break the build and test on PHP 7.1 (#12, #14 and #19 by @clue and #16 by @Nyholm)

Feature: Support accessing built-in filters as callbacks (#5 by @clue)

$fun = Filter\fun('zlib.deflate');

$ret = $fun('hello') . $fun('world') . $fun();
assert('helloworld' === gzinflate($ret));
