Python-augeas

- Support for context-free lenses via the 'let rec' keyword. The syntax
is experimental, though the feature is here to stay. See
lenses/json.aug for an example of what's possible with that.
- Support for case-insensitive regular expressions. Simply append 'i' to
a regexp literal to make it case-insensitive, e.g. /hello/i will match
all variations of hello, regardless of case.
- Major revamp of augtool. In particular, path expressions don't need to
be quoted anymore. The online help has been greatly improved.
- Check during load/save that each file is only matched by one transform
under /augeas/load. If there are multiple transforms for a file, the
file is skipped.
- New error codes AUG_ENOLENS and AUG_EMXFM
- Do not choke on non-existing lens during save
- Change the metadata for files under /augeas/files slightly: the node
/augeas/files/$PATH/lens now has the name of the lens used to load the
file; the source location of that lens has moved to
/augeas/files/$PATH/lens/info
- New public functions fa_nocase, fa_is_nocase, and fa_expand_nocase in
libfa
- Various smaller bug fixes, performance improvements and improved error
messages

nodeset

- Clean up interface for libfa; the interface is now considered stable
- New aug_load API call; allows controlling which files to load by
modifying /augeas/load and then calling aug_load; on startup, the
transforms marked with autoload are reported under /augeas/load
- New flag AUG_NO_LOAD for aug_init to keep it from loading files on
startup; add --noload option to augtool
- New API calls aug_defvar and aug_defnode to define variables for
path expressions; exposed as 'defvar' and 'defnode' in augtool
- Lenses distributed with Augeas are now installed in
/usr/share/augeas/lenses/dist, which is searched after
/usr/share/augeas/lenses, so that lenses installed by other packages
take precedence
- New program examples/fadot to draw various finite automata (Francis
Giraldeau)
- Report line number and character offset in the tree when parsing a
file with a lens fails
- Fix error in propagation of dirty flag, which could lead to only
parts of a tree being saved when multiple files were modified

- Fix a number of memory corruptions in the XPath evaluator
- Several performance improvements in libfa
