+We fixed exporting of C<is_strict> and C<is_lax> from L<version>.
These were being exported with a wrapper that treated them as method
-calls, which causes them to fail. They are just functions, are
+calls, which caused them to fail. They are just functions, are
documented as such, and should never be subclassed, so this patch
just exports them directly as functions without the wrapper.
We upgraded L<Pod::Simple> to version 3.14 to get an improvement to \C\<\< \>\>
parsing.

+
+C<List::Util::first> misbehaves in the presence of a lexical C<$_>
+(typically introduced by C<my $_> or implicitly by C<given>). The variable
+which gets set for each iteration is the package variable C<$_>, not the
+lexical C<$_>.
+
+A similar issue may occur in other modules that provide functions which
+take a block as their first argument, like
+
+ foo { ... $_ ...} list

+C<Module::Load::Conditional> and C<version> have an unfortunate
+interaction which can cause C<CPANPLUS> to crash when it encounters
+an unparseable version string. Upgrading to C<CPANPLUS> 0.9004 or
+C<Module::Load::Conditional> 0.38 from CPAN will resolve this issue.
