This is release 1.2 of bibview.

In this release the following changes were made:

- The grammar was enhanced to accept erroneous input.
  In case of entries with errors, the key of the entry
  is printed to stderr.
- The option "Ignore Case" was added (default: TRUE).
  When this option is chosen, uppercase/lowercase
  distinctions are ignored during comparisons in a search.
  The search functions now use <regex.h> instead of
  <regexp.h>.
  If you don't have <regex.h>, you have to replace db_tree.c 
  by dbt_tree-regexp.c.
- The backup mechanism was improved to be able to keep
  multiple backups.
- If duplicate keys are discovered, the BibTeX key
  is changed by appending an "a".
- The headline of the list window was changed to really show
  the beginning of the columns.
- The AVL functions in the file db_tree.c were replaced by
  those posted by Lee Hollingworth.
- Some bugs were removed that caused a segmentation fault.

In release 1.1 the following changes were made:

- The grammar was enhanced to accept comments.
  WARNING: The comments will get lost in the file that
           bibview produces.
- bibview will accept user defined entry types
  that differ from the standard entry types. The fields of
  these entries are treated as user defined fields. It is not
  possible to do a search on these fields. This feature is not
  very comfortable, but it will bibview make more universally
  usable.
- The default of the option "Autom. Check" was changed to FALSE.
- The effect of the option "Required Fields" has changed.
  If "Required Fields" is on, a warning is displayed when
  trying to save an incomplete entry.
  If "Required Fields" is off, an incomplete entry is save without
  warning.
- There is a change in the directory mechanism of the FileSelectBox.
  The directory where the file selection process starts is the
  directory where the last file selection process has taken place.
  There is the possibility to enter a default directory where
  BibTeX files are usually found with the [BibDir] part of
  the configuration file.
- The resource file was split into a part BibView.ad and
  BibView-co.ad.
- Some bugs are removed that caused a segmentation fault.
