 Version 1.5 (13 January 2012)
* The utilities will now ask interactively for a password if it was
  not provided with the -s command line option.  This avoids security
  problems related to shell history files.

  be used in both the records and selection expressions.

  output records.
* The new -q (quick) option allows to quickly search for the desired
  record without having to provide a complete selection expression.
* Auto generated fields are now considered integers by default.  This
  avoids repetitive patterns in record descriptors involving %auto and
  %type.

  improved.

  as ob-rec.el.  It allows to read rec data into org documents in both
  raw and table formats.

  literals in selection expressions, as well as single quotes.
  Unescapted newline characters are also supported.
* The manual has been vastly improved.

  generating time-stamps in auto-fields.
* Lots of bug fixes.

 Version 1.3 (11 February 2011)
* A quite bad (and embarrassing) bug introduced in 1.2 has been
  fixed.  The bug was causing recins, recdel and recset to report
  random integrity failures, due to a uninitialized variable.

* Support for auto-incremented fields and timestamps with the new
  %auto field in record descriptors.

  expressions and type descriptions is now documented in the user
  manual.
