  - 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

  - Bug fixes in path expressions
    * for numbers, the meaning of '<' and '<=' was reversed

0.3.5 - 2008-12-23
  - add an option to rewrite files by overwriting their contents instead of
    putting the new file in place atomically with rename(2); file contents
    are only copied after rename fails with EXDEV or EBUSY, and only if the
    node /augeas/save/copy_if_rename_fails (fix #32)
  - saving of backup (.augsave) files now works even if the original and
    backup files are on different devices
  - major refactoring of how path expressions are handled internally. Fixes

    to aug_init, aug_save would always fail

0.3.3 - 2008-10-24
  - restore the behavior of aug_save; in 0.3.2, aug_save broke API by
    returning the number of files changed on success instead of 0

0.3.2 - 2008-10-21
  - saving now reports which files were actually changed in
    /augeas/events/saved; aug_save also returns the number of files
    that were changed
  - preserve file owner, permissions and SELinux context when changing a file.
  - make saving idempotent, i.e. when a change to the tree does not result
    in changes to the actual file's content, do not touch the original file
  - report an error if there are nodes in the tree with a label that
    is not allowed by the lens
  - quietly append a newline to files that do not have one
  - generate lens documentation using NaturalDocs and publish those
    on the Auegas website (Raphael Pinson)

0.3.1 - 2008-09-04
  - Major performance improvement when processing huge files, reducing some
    O(n^2) behavior to O(n) behavior. It's now entirely feasible to
    manipulate for example /etc/hosts files with 65k lines
  - Handle character escapes '\x' in regular expressions in compliance with
    Posix ERE
  - aug_mv: fix bug when moving at the root level
  - Fix endless loop when using a mixed-case module name like MyMod.lns
  - Typecheck del lens: for 'del RE STR', STR must match RE
  - Properly typecheck the '?' operator, especially the atype; also allow
    '?' to be applied to lenses that contain only 'store', and do not
    produce tree nodes.
  - Many new/improved lenses
    * many lenses now map comments as '#comment' nodes instead of just
      deleting them

    * reduce overall memory usage by releasing unused compiled regexps

    (FA_AS_REGEXP)
  - New lenses
    * /etc/fstab
    * /etc/xinetd.conf and /etc/xinetd.d/*

0.1.0 - 2008-05-01
  - Various changes to public API:
    * Remove aug_exists from public API, and merge functionality into aug_get
    * Do not hide pointer behind typedef; instead Augeas 'handle' type is now
      struct augeas, typedef'd to augeas (Jim Meyering)

0.0.8 - 2008-04-16
  - Complete rewrite of the language for schema descriptions

0.0.7 - 2008-03-14
  - Typecheck lenses; in particular, discover and complain about ambiguous
    concatenation and iteration
  - Enable typechecking for augparse by default, and for augtool via the
    '-c' flag
  - Fixed lens definitions in spec/ to pass typechecking. They contained
    quite a few stupid and subtle problems
  - Greatly improved libfa performance to make typechecking reasonably
    fast. Typechecking cmfm.aug went from more than two hours to under two
    seconds

0.0.6 - 2008-03-05
  - Make it possible to overwrite files when saving with and without
    backups

  - Expose these two things as command line options in augtool

    more closely
  - major revamp of the internal tree representation (ordered tree where
    multiple children can have the same label, including NULL labels)
  - move away from LL(1) parsing in favor of regular languages, since they
    enable much better ahead-of-time checks (which are not implemented yet)

0.0.2 - 2008-01-29:
  - completely reworked
  - processing of files is now based on a textual description of the
    structure of the files (basically a LL(1) grammar)

0.0.1 - 2007-12-01:
  - First release.
  - Public API and basic tree data structure.
  - Record scanning works.
  - Providers for pam.d, inittab and /etc/hosts
