=head1 DESCRIPTION
This document describes differences between the 5.9.0 and the 5.9.1
-developement releases. See L<perl590delta> for the differences between
+development releases. See L<perl590delta> for the differences between
5.8.0 and 5.9.0.
=head1 Incompatible Changes
The lvalues returned by the three argument form of substr() used to be a
"fixed length window" on the original string. In some cases this could
cause surprising action at distance or other undefined behaviour. Now the
-length of the window adjusts iself to the length of the string assigned to
+length of the window adjusts itself to the length of the string assigned to
it.
=head2 The C<:unique> attribute is only meaningful for globals
When configured with long doubles, perl may fail tests 224-236 in
F<t/op/pow.t> on the same platform.
+For threaded builds, F<ext/threads/shared/t/wait.t> has been reported to
+fail some tests on HP-UX 10.20.

=head1 To-do for perl 5.10.0
This is a non-exhaustive, non-ordered, non-contractual and non-definitive
Make threads more robust.
-Make C<no 6> and C<no v6> work.
+Make C<no 6> and C<no v6> work (opposite of C<use 5.005>, etc.).
A test suite for the B module would be nice.
