+# Announce: Rakudo Perl 6 compiler, Release 2019.07.1
+
+On behalf of the Rakudo development team, I'm announcing an
+out-of-schedule release of the Rakudo Perl 6 compiler.
+Rakudo is an implementation of Perl 6 on the Moar Virtual Machine[^1].
+
+This release is a point release in addition to the regular
+releases. Rakudo 2019.07 (note: no .1) was discovered to have some
+issues with the build system that affected packaging. Moreover, this
+release comes with a corresponding MoarVM point release which has some
+important stability and reliability fixes.
+
+The tarball for this release is available from <https://rakudo.org/files/rakudo>.
+
+Please note: This announcement is not for the Rakudo Star
+distribution[^2] — it’s announcing a new release of the compiler
+only. For the latest Rakudo Star release, see
+<https://rakudo.org/files/star>.
+
+The changes in this release are outlined below:
+

+    + Fixed unnecessary use of `git` in release tarballs [540926bf][e18b4f3b]
+    + Fixed intermittent failures in one of the performance tests [bd29d3f6]
+
+The following people contributed to this release:
+
+Patrick Böker, Aleks-Daniel Jakimenko-Aleksejev, Timo Paulssen,
+Jonathan Worthington, Stefan Seifert, Samantha McVey
+
+If you would like to contribute or find out more information, visit
+<https://perl6.org>, <https://rakudo.org/how-to-help>, ask on the
+<perl6-compiler@perl.org> mailing list, or ask on IRC #perl6 on freenode.
+
+Additionally, we invite you to make a donation to The Perl Foundation
+to sponsor Perl 6 development: <https://donate.perlfoundation.org/>
+(put “Perl 6 Core Development Fund” in the ‘Purpose’ text field)
+
+The next release of Rakudo (#132), is tentatively scheduled for 2019-09-21.
+
+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.

+
+[^2]: What’s the difference between the Rakudo compiler and the Rakudo
+Star distribution?
+
+The Rakudo compiler is a compiler for the Perl 6 language.
+Not much more.
+
+The Rakudo Star distribution is the Rakudo compiler plus a selection
+of useful Perl 6 modules, a module installer, Perl 6 introductory
+documentation, and other software that can be used with the Rakudo
+compiler to enhance its utility.
