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 `use v6.c` | ||
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. | ||
|
||
If you would like to contribute or get more information, visit | ||
<https://raku.org>, <https://rakudo.org/community>, ask on the | ||
<perl6-compiler@perl.org> mailing list, or ask on IRC #raku on Libera. | ||
|
||
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 (#153), is tentatively scheduled for 2022-01-21. | ||
|
||
A list of the other planned release dates is available in the | ||
“docs/release_guide.pod” file. | ||
|
||
The development team appreciates feedback! If you’re using Rakudo, do | ||
get back to us. Questions, comments, suggestions for improvements, cool | ||
discoveries, incredible hacks, or any other feedback – get in touch with | ||
us through (the above-mentioned) mailing list or IRC channel. Enjoy! | ||
|
||
Please note that recent releases have known issues running on the JVM. | ||
We are working to get the JVM backend working again but do not yet have | ||
an estimated delivery date. | ||
