v1.4.1

• 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)

v1.4.0

• 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)

v1.3.0

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