    I think it's important to note that 5.11.x releases are DEVELOPMENT releases, meaning they are unsuitable for production use.

    The idea behind dev releases is to give an advance glimpse into the next production release and to give a chance for people to see if the next production release breaks their code. If issues are found, they can be addressed before it's too late.

      I just installed it, and it came with these stray test files
      C:/perl/5.11.1/lib/Devel/DProf/test1_v C:/perl/5.11.1/lib/Devel/DProf/test2_t C:/perl/5.11.1/lib/Devel/DProf/test2_v C:/perl/5.11.1/lib/Devel/DProf/test3_t C:/perl/5.11.1/lib/Devel/DProf/test3_v C:/perl/5.11.1/lib/Devel/DProf/test4_t C:/perl/5.11.1/lib/Devel/DProf/test4_v C:/perl/5.11.1/lib/Devel/DProf/test5_t C:/perl/5.11.1/lib/Devel/DProf/test5_v C:/perl/5.11.1/lib/Devel/DProf/test6_t C:/perl/5.11.1/lib/Devel/DProf/test6_v C:/perl/5.11.1/lib/Devel/DProf/test7_t C:/perl/5.11.1/lib/Devel/DProf/test7_v C:/perl/5.11.1/lib/Devel/DProf/test8_t C:/perl/5.11.1/lib/Devel/DProf/test8_v

    Package declarations can now include a version number.
    huh? To replace $VERSION? That sounds a little odd to me.
      No, to set $VERSION
      package Foo 1.23;
      is roughly the same as
      package Foo; BEGIN { our $VERSION = 1.23; }

        Nice, because it is symmetric to use Foo 1.07.


        Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)

    why end NT4 support if other server OS, that is still used a bit in business if other *nixes withe compareable installbase are still suported?

    Kephra, a beautiful Perl Editor, designed along Perl like Paradigms lives at

      Because nobody is running tests for NT4. It's not that newer Perl releases won't run on NT4, but there is nobody testing the compilation of Perl on NT4, and thus it falls out of the observable universe of Perl.

      For Win9x, the situation is even worse, not only is there nobody testing, but even building on Win9x is impossible due to being the shell. Dropping Win9x support has the actual benefit of being able to drop some dynamic loading of API functions and thus simplifying some conditional code.

      Surely it's because there is a lack of resources to support it. I'm sure they would support it if they could.

      It doesn't mean that Perl won't run on NT4. It doesn't mean that fixes for NT4 will be ignored.

      It means they have no way of knowing whether NT4 is broken or they don't currently have the means to fix it if it does break.

      There is another possibility: Dropping support for NT4 will allow them to simplify code by using features introduced in a newer OS.

      It may be possible to emulate those features in NT4, but if so, noone has indicated the capability and will to do so.

      And then there's the likelyhood that someone running an OS older than Perl 5.6 isn't going to be installing Perl 5.12.
