For an overview of what's changed in this release, see pod/perldelta.pod. For the details of changes in previous releases, see the individual perlNNNdelta.pod files. For example, pod/perl588delta.pod describes the changes between versions 5.8.7 and 5.8.8. For a list of contributors to perl, see AUTHORS. If you need a detailed commit history (i.e. descriptions of each individual commit), you can view the git version control history online at http://perl5.git.perl.org/perl.git (follow the 'shortlog' link beside the relevant tag). Or, you can download a copy of the git repository and then run a command like git log --name-status v5.13.9..v5.13.10 to view all the changes between 5.13.9 and 5.13.10. See pod/perlgit.pod for more details on using git and accessing the commit history. In perl releases prior to 2009, the source tarball included a collection of Changes files that listed the individual commits that had gone into each release. Since these files had become very large, and since the same information is now freely available online, it was decided to remove them from subsequent releases. If you need access to these removed files, then they can be be found most recently in the 5.8.9 and 5.10.0 tarballs, at http://www.cpan.org/src/perl-5.8.9.tar.gz http://www.cpan.org/src/5.0/perl-5.10.0.tar.gz The contents of the files in question can mostly be regenerated using git commands. The following table shows the equivalents. Note that the files prior to Changes5.005 were not simple lists of commits, so can't be recreated just by running the git command. As it happens, even the latter ones are not exact equivalents. This is due to a combination of errors in the original Changes files, and "impedance mismatches" when the previous version control data was imported into git in December 2008. For example, the Changes5.005 file includes 206 spurious entries from the maint5.004 Perforce branch. Running the following command with the range argument shown in the table will produce *approximately* the same list of changes in the specified file shown from the listed tarball. git log --name-status file tarball argument to 'git log' ------------ ------ -------------------------------- Changes5.000 Either N/A Changes5.001 Either perl-5.000..perl-5.001 Changes5.002 Either perl-5.001..perl-5.002 Changes5.003 Either perl-5.002..perl-5.003 Changes5.004 Either perl-5.003..perl-5.004 Changes5.005 Either perl-5.004..perl-5.005_03 Changes5.6 Either perl-5.005_03..perl-5.6.0 Changes5.8 Either perl-5.6.0..perl-5.8.0 Changes5.8.1 5.8.9 perl-5.8.0..perl-5.8.1 ^1ede746b Changes5.8.2 5.8.9 perl-5.8.1..perl-5.8.2 Changes5.8.3 5.8.9 perl-5.8.2..perl-5.8.3 Changes5.8.4 5.8.9 perl-5.8.3..perl-5.8.4 Changes5.8.5 5.8.9 perl-5.8.4..perl-5.8.5 ^3a81978b Changes5.8.6 5.8.9 perl-5.8.5..perl-5.8.6 ^498d59dd Changes5.8.7 5.8.9 perl-5.8.6..perl-5.8.7 Changes5.8.8 5.8.9 perl-5.8.7..perl-5.8.8 Changes 5.8.9 perl-5.8.8..perl-5.8.9 Changes 5.10.0 perl-5.8.0..perl-5.10.0
