This release implements 6.c and 6.d versions of the Raku specification.
6.c version of the language is available if you use the
version pragma, otherwise 6.d is the default.
Upcoming releases in 2022 will include new functionality that is not part of 6.c or 6.d specifications, available with a lexically scoped pragma. Our goal is to ensure that anything that is tested as part of 6.c and 6.d specifications will continue to work unchanged. There may be incremental spec releases this year as well.

Additionally, we invite you to make a donation to The Perl Foundation to sponsor Raku development: https://donate.perlfoundation.org/ (put “Raku Core Development Fund” in the ‘Purpose’ text field)
The next release of Rakudo (#159), is tentatively scheduled for 2023-02-03.
A list of the other planned release dates is available in the “docs/release_guide.pod” file.
