New supported release 7.3.0 "Peach-faced Lovebird"

"The rosy-faced lovebird is a fairly small bird, 17–18 cm long with an average wing length of 106 mm and tail length of 44–52 mm. Populations have been reduced in some areas by trapping for the pet trade. However numbers may have increased in other parts due to human creation of new water sources and the building of artificial structures which provide new nesting sites." - en.wikipedia.org/wiki/Peach-faced_lovebird

Parrot 7.2.0 "Blue-crowned racquet-tail" released!

    This is the bright candlelit room where the life-timers are
    stored—shelf upon shelf of them, squat hourglasses, one for every
    living person, pouring their fine sand from the future into the past.
    The accumulated hiss of the falling grains makes the room roar like
    the sea.

    This is the owner of the room, stalking through it with a preoccupied air.
    His name is Death.

    But not any Death. This is the Death whose particular sphere of
    operations is, well, not a sphere at all, but the Discworld, which is
    flat and rides on the back of four giant elephants who stand on the
    shell of the enormous star turtle Great A’Tuin, and which is bounded by
    a waterfall that cascades endlessly into space.

    Scientists have calculated that the chance of anything so patently
    absurd actually existing are millions to one.

    But magicians have calculated that million-to-one chances crop up nine
    times out of ten.

Parrot 7.1.0 "Lilian's Lovebird" released

"Recently, cases of Lilian's lovebird poisoning have intensified although it is not known why poachers are poisoning the birds. Lilian's lovebird researchers assume poachers mean to poison larger mammals and lovebirds fall victims." - en.wikipedia.org/wiki/Lilian%27s_lovebird#Threats

Parrot 7.0.2 Hotfix released

We detected and fixed two bugs and regressions from 6.10.0 which failed to build parrot on Microsoft Windows with Microsoft Visual Studio C++.

- Wrong function ptr cast
  https://github.com/parrot/parrot/issues/1190
- Wrong SAL annotations (also 32 bit)
  https://github.com/parrot/parrot/issues/1192

Other minor changes in this hotfix:

Parrot 7.0.1 Hotfix released

We detected and fixed two serious and two minor bugs which required a 7.0.1 hotfix release.

- GC regression --optimize caused by PARROT_CANNOT_RETURN_NULL, which 
was visible on machines with low memory. 
https://github.com/parrot/parrot/issues/1186

This causes segfaults with --optimize, which is the default for nqp
and rakudo, on better (i.e. newer) compilers. The bug was there since
3.6, but turned evil only with 7.0, when packfile got refactored.

- threads deadlock in gc_gms_mark_and_sweep()
https://github.com/parrot/parrot/issues/1187

With cc -O3 the lock code is too far away from the guard, thus causing
our threads example examples/threads/chameneos.pbc to hang, a
regression from 6.11.0

And 2 minor ones for --m=64 or --m=32:

- fix --m=64 with gcc on ppc64 and mips64 #1181,

--m=64 produced wrong ld and linkflags since 6.10, GH #1110

- fix icu probes with --m #1182

We never linked icu again the libs in the configure step, so we failed
to detect wrong architectures, and worse, added wrong arch include and
libpaths to the flags (e.g. amd64 --m=32), causing all sorts of icu
errors, when has_icu=1 but either linking or runtime failed. This
always caused problems.

Parrot 7.0.0 "Crimson Shining Parrot" released

"We'll show him! We'll show them *all*!"

"Okay," said Susan, "that was *definitely* evil -"

"No," said Lavender, "that's a Chaos Legion motto, actually. Only she
didn't do the insane laughter."

"That's right," Tracey said, her voice low and grim. "This time I'm not
laughing." The girl went on stalking through the corridor, like she had
dramatic music accompanying her that only she could hear.

(Hermione was starting to worry about what *exactly* the impressionable
youths of the Chaos Legion were learning from Harry Potter.)

Parrot 6.10.0 "New Caledonian lorikeet" released

    Now instead of four in the eights place
    You've got three,
    'Cause you added one,
    That is to say, eight, to the two,
    But you can't take seven from three,
    So you look at the sixty-fours...

    Sixty-four?  "How did sixty-four get into it?"  I hear you cry!
    Well, sixty-four is eight squared, don't you see?
        -- Tom Lehrer, "New Math"

New supported release Parrot 6.9.0 "Rosy-faced Lovebird"

On behalf of the Parrot team, I'm proud to announce the new supported release Parrot 6.9.0, also known as "Rosy-faced Lovebird". Parrot is a virtual machine aimed at running all dynamic languages.
