then bump the version numbers of any non-dual-life modules that have

number. If there is more than one maintenance branch (e.g. 5.8.x, 5.10.x),
then compare against both.
+Be sure to bump the version numbers in separate commits for each module
+(or group of related modules) so that changes can be cherry-picked later
+if necessary.

to lib/, or a script like lib/lib_pm.PL is run to produce lib/lib.pm);
make sure you edit the correct file!

also sensible.

-A week or two before the first release candidate, bump the perl version
-number (e.g. from 5.10.0 to 5.10.1), to allow sufficient time for testing
-and smoking with the target version built into the perl executable. For
-subsequent release candidates and the final release, it it not necessary
-to bump the version further.
+Bump the version number (e.g. from 5.12.0 to 5.12.1).
+
+For a blead release, this can happen on the day of the release. For a
+release candidate for a stable perl, this should happen a week or two
+before the first release candidate to allow sufficient time for testing and
+smoking with the target version built into the perl executable. For
+subsequent release candidates and the final release, it it not necessary to
+bump the version further.
There is a tool to semi-automate this process. It works in two stages.
First, it generates a list of suggested changes, which you review and
rename perl-5^.10^.1.dir perl-5_10_1.dir
-Have a look a couple lines up from that. You'll see roman numerals.
-Update those too. Find someone with VMS clue if you have to update
-the Roman numerals for a .0 release.
+When doing a blead release, also make sure the C<PERL_API_*> constants in
+F<patchlevel.h> are in sync with the with the version you're releasing, unless
+you're absolutely sure the release you're about to make is 100% binary
+compatible to an earlier release. When releasing a stable perl version, the
+C<PERL_API_*> constants C<MUST NOT> be changed as we aim to guarantee binary
+compatibility in maint branches.
Commit your changes:
$ git st

- B<review the delta carefully>
+ $ git diff

$ git commit -a -m 'Bump the perl version in various places for 5.x.y'
+When the version number is bumped, you should also update Module::CoreList (as
+described below in L<"Building a release - on the day">) to reflect the new
+version number.

Review and update INSTALL to account for the change in version number;
in particular, the "Coexistence with earlier versions of perl 5" section.
+Be particularly careful with the section "Upgrading from 5.X.Y or earlier". For
+stable releases, this needs to refer to the last release in the previous
+development cycle. For blead releases, it needs to refer to the previous blead
+release.

+Finalize the perldelta. In particular, fill in the Acknowledgements

+ perl Porting/checkAUTHORS.pl --who -
+
Re-read the perldelta to try to find any embarrassing typos and thinkos;
remove any C<TODO> or C<XXX> flags; update the "Known Problems" section
with any serious issues for which fixes are not going to happen now; and
run through pod and spell checkers, e.g.
- $ podchecker -warnings -warnings pod/perl5101delta.pod
- $ spell pod/perl5101delta.pod
+ $ podchecker -warnings -warnings pod/perldelta.pod
+ $ spell pod/perldelta.pod
Also, you may want to generate and view an HTML version of it to check
formatting, e.g.
- $ perl pod/pod2html pod/perl5101delta.pod > /tmp/perl5101delta.html
+ $ perl pod/pod2html pod/perldelta.pod > /tmp/perldelta.html
+
+Another good HTML preview option is http://search.cpan.org/pod2html

It is VERY important that from this point forward, you not push
your git changes to the Perl master repository. If anything goes
wrong before you publish your newly-created tag, you can delete

F<../perl-x.y.z-RC1.tar.gz>. With C<-b>, it also creates a C<tar.bz2> file.

$ bin/perl -MCPAN -e'shell'
+(Use C<... -e "shell"> instead on Win32. You probably also need a set of

Bootstrap the CPANPLUS client on the clean install:

+(Again, on Win32 you'll need something like Cygwin installed, but make sure
+that you don't end up with its various F<bin/cpan*> programs being found on
+the PATH before those of the Perl that you're trying to test.)
+
=item *
Install an XS module, for example:
(Login, then select 'Upload a file to CPAN')
+If your workstation is not connected to a high-bandwidth,
+high-reliability connection to the Internet, you should probably use the
+"GET URL" feature (rather than "HTTP UPLOAD") to have PAUSE retrieve the
+new release from wherever you put it for testers to find it. This will
+eliminate anxious gnashing of teeth while you wait to see if your
+15 megabyte HTTP upload successfully completes across your slow, twitchy
+cable modem. You can make use of your home directory on dromedary for
+this purpose: F<http://users.perl5.git.perl.org/~USERNAME> maps to
+F</home/USERNAME/public_html>, where F<USERNAME> is your login account
+on dromedary. I<Remember>: if your upload is partially successful, you
+may need to contact a PAUSE administrator or even bump the version of perl.
+
Upload both the .gz and .bz2 versions of the tarball.
+Wait until you receive notification emails from the PAUSE indexer
+confirming that your uploads have been received. IMPORTANT -- you will
+probably get an email that indexing has failed (due to dual-life modules,
+apparently). This is considered normal.
+
+Do not proceed any further until you are sure that your tarballs are on
+CPAN. Check your authors directory on one of the "fast" CPAN mirrors
+(e.g. cpan.shadowcatprojects.net, cpan.dagolden.com, cpan.hexten.net
+or cpan.cpantesters.org) to confirm that your uploads have been successful.

-Bump the perlXYZ version number.
+Create a new perldelta.
+
+First, move the existing F<pod/perldelta.pod> to F<pod/perlNNNdelta.pod> (where
+NNN is the perl version number without the dots. i.e. 5134 for 5.13.4).
+
+Now edit the moved delta file to change the C<NAME> from C<perldelta> to
+C<perlNNNdelta>.
-First, create a new empty perlNNNdelta.pod file for the current release + 1;
-
see F<Porting/how_to_write_a_perldelta.pod>.
+Then create a new empty perldelta.pod file for the new release; see
+F<Porting/how_to_write_a_perldelta.pod>.
You should be able to do this by just copying in a skeleton template and
then doing a quick fix up of the version numbers, e.g.
- $ cp -i Porting/perldelta_template.pod pod/perl5102delta.pod
- $ (edit it)
- $ git add pod/perl5102delta.pod
+Then commit the move and the new file.
+
+For example, assuming you just released 5.10.1:
+
+ $ git mv pod/perldelta.pod pod/perl5101delta.pod
+ $ (edit pod/perl5101delta.pod to retitle)
+ $ git add pod/perl5101delta.pod
+
+ $ cp -i Porting/perldelta_template.pod pod/perldelta.pod
+ $ (edit pod/perldelta.pod)
+ $ git add pod/perldelta.pod
+ $ git commit -m 'create perldelta for 5.10.2'
+
+Now you need to update various tables of contents, most of which can be
+generated automatically.
-Edit F<pod.lst>: add the new entry, flagged as 'D', and unflag the previous
-entry from being 'D'; for example:
+Edit F<pod.lst>: add the new entry, flagged as 'd', and unflag the previous
+entry from being 'd'; for example:
- -D perl5101delta Perl changes in version 5.10.1
- +D perl5102delta Perl changes in version 5.10.2
+ -d perl5101delta Perl changes in version 5.10.1
+ +d perl5102delta Perl changes in version 5.10.2
+ perl5101delta Perl changes in version 5.10.1
Run C<perl pod/buildtoc --build-all> to update the F<perldelta> version in
Then manually edit (F<vms/descrip_mms.template> to bump the version
in the following entry:
- [.pod]perldelta.pod : [.pod]perl5101delta.pod
+ [.pod]perl5101delta.pod : [.pod]perldelta.pod
XXX this previous step needs to fixed to automate it in pod/buildtoc.
-Manually update references to the perlNNNdelta version in these files:
-
- INSTALL
- README
-
-Edit the previous delta file to change the C<NAME> from C<perldelta>
-to C<perlNNNdelta>.
-
-These two lists of files probably aren't exhaustive; do a recursive grep
-on the previous filename to look for suitable candidates that may have
-been missed.
-
Finally, commit:
- $ git commit -a -m 'create perlXXXdelta'
+ $ git commit -a -m 'update TOC for perlNNNdelta'
At this point you may want to compare the commit with a previous bump to
see if they look similar. See commit ca8de22071 for an example of a
previous version bump.
