# pperl 0.6.8

*2026-07-27 to 2026-07-28, 3 commits.*

- **`--cpan`** installs pure-Perl CPAN distributions for pperl. Modules
  built into pperl count as installed at pperl's own version, not at
  the host perl's, so they are never rebuilt.
- **ExtUtils::MakeMaker**: a distribution's `Makefile.PL` runs and
  writes the same Makefile as on perl5. `B::svref_2object(\$v)->MAGIC`
  died for lack of a `B::MAGIC` class, which stopped every
  `Makefile.PL`; `B::MAGIC` now exists with its accessors.
  `$Config{eunicefix}` is `:` as on perl5, so MakeMaker no longer
  executes the Makefile it has just written.
- **The daemon**: `pperl --via-daemon script.pl` runs the script from
  its cached compiled image, as `PPERL_DAEMON=2` does; the reduced mode
  that a bare `--via-daemon` used to select is now `--via-daemon=trunk`,
  and any other value is refused with the accepted forms.
  `--via-daemon=script` and `PPERL_DAEMON=2`, documented as the same
  request, kept separate caches, so a script run both ways was never
  served from its cached image again; they now share one.
- **Safe**: a subroutine signature inside a `Safe` compartment was
  denied, because `Opcode` took its op tags from the host perl's
  `Opcode.pm`, which lacks the signature ops of perl 5.44. The tag
  table is now part of pperl, and the host perl's `Opcode.pm` is no
  longer loaded.
- **Encode**: an encoding alias registered at run time works with
  `encode` and `decode`, not only with `resolve_alias`.
- **PDL**: slicing a slice no longer checks bounds against an unset
  shape, `sever` detaches an ndarray from its parent, and operations
  with a scalar on a `flowing` ndarray no longer leave empty results or
  crash.
- **Daemon guide**: the chapter "Fast start-up: the daemon" gains a
  worked example (about 24 ms per cold run against about 4 ms from the
  cached image, on the machine it was written on), how to check whether
  a run was served, how to opt in from a shebang line or a shell
  function, a systemd user unit, and an exact description of
  `--daemon-idle`.
