If you are upgrading from an earlier release such as 5.12.1, first readperl5122delta, which describes differences between 5.12.1 and5.12.2. The major changes made in 5.12.0 are described in perl5120delta.

Incompatible Changes

 There are no changes intentionally incompatible with 5.12.2. If any
  exist, they are bugs and reports are welcome.

Core Enhancements

`keys`, `values` work on arrays

You can now use the keys, values, each builtin functions on arrays(previously you could only use them on hashes). See perlfunc for details.This is actually a change introduced in perl 5.12.0, but it was missed fromthat release's perldelta.

Bug Fixes

"no VERSION" will now correctly deparse with B::Deparse, as will certainconstant expressions.

Module::Build should be more reliably pass its tests under cygwin.

Lvalue subroutines are again able to return copy-on-write scalars. Thishad been broken since version 5.10.0.

Platform Specific Notes

Solaris
A separate DTrace is now build for miniperl, which means that perl can becompiled with -Dusedtrace on Solaris again.
VMS
A number of regressions on VMS have been fixed. In addition to minor cleanupof questionable expressions in vms.c, file permissions should no longer begarbled by the PerlIO layer, and spurious record boundaries should no longer beintroduced by the PerlIO layer during output.
For more details and discussion on the latter, see:
```

```
VOS
A few very small changes were made to the build process on VOS to bettersupport the platform. Longer-than-32-character filenames are now supported onOpenVOS, and build properly without IPv6 support.
