>>> Hey! be more positive! Suggested rewording:

The abc team is pleased to announce the release of version 1.2.1 of abc.
Highlights include the following:

* An improved implementation of tracematches. In particular the new
  indexing optimisation is now based on our own implementation of
  a weak reference map, eliminating problems that were due to
  the earlier use of the Apache commons collections. This is the
  world's first robust, efficient implementation of this type of
  language feature, so we're very keen on feedback! A separate set
  of examples and benchmarks can be found at

   http://abc.comlab.ox.ac.uk/packages/tmbenches.{tar.gz,zip}

  Full technical details are described in our technical report

   http://abc.comlab.ox.ac.uk/documents/abc-2006-1.{pdf,ps}

* In anticipation of new extensions that are in the works, we have
  also reworked the reweaving analysis infrastructure, so multiple
  reweaving analyses can be used simultaneously

* Finally, this release contains many bug fixes, and it upgrades
  to Polyglot 1.3.3 as well as the latest versions of Soot and
  Paddle.
