Augeas

Files can be optionally changed in place if
rename(2) fails. Several path expression bugs were
fixed. Many new lenses were added.

Saving of backup files was fixed: in 0.3.3, when
AUG_SAVE_BACKUP was passed to aug_init, aug_save
would always fail.

An API regression was fixed: aug_save now returns
0 on success. Version 0.3.2 broke that by
returning the number of saved files, which broke
various clients.

Various fixes for file saving (preserving the file attributes/SELinux label, reporting which files were changed, and making save idempotent). Lens documentation is generated with NaturalDocs. There are various lens fixes and enhancements.

Processes many more config files, including configs for sudoers, puppet, OpenLDAP, OpenVPN, dhclient, Samba, Slapd, dnsmasq, and sysctl. Improvements to many existing lenses, including better handling of shell variable assignments, and handling of comments and whitespace in /etc/hosts, /etc/fstab, xinetd, php.ini, dput.conf, and pam.d. Major performance improvements when processing large files. Several important bugfixes.
