     <h1>Equinox Aspects 1.0 M6 - New and Noteworthy</h1>

     <p>
       During the M6 timeframe we had a lot of very fruitful discussions with the AJDT team
       to make Equinox Aspects easier to use and to have more fine-grained control of the
       actual weaving. The goal of M7 will be to implement those changes.

           Because of some major improvements within the loadtime weaving implementation
           of AspectJ we now have a version dependency on at least version 1.6.2 of the
           AspectJ weaver package imports. This avoids confusion if you have multiple versions
           of those packages installed (which is the case if you have AJDT and SpringIDE
           installed together, for example). If you have the latest AJDT versions in use,
           you should have no problems. If you definitely need Equinox Aspects to work with
           older AspectJ weaver versions, please let us know.

           We got some bug reports regarding the standard cache implementation. That seemed to
           cause problems with the file handling in some (mostly OS-dependent) situations.
           The major problem was that those problems caused the complete system to hang. We
           now reimplemented the cache writing for the standard caching service to an asynchronous
           mode. Woven class bytecodes are put into a bounded concurrent queue and a different
           thread takes care to write those bytes to the appropriate directory. This makes the
           cache handing even faster since the thread that caused the weaving is no longer used
           to write the bytes to the cache and can continue right away.
