| <h1>Equinox Aspects 1.0 M3 - New and Noteworthy</h1> |
| |
| <p> |
| These days the Equinox Aspects incubator project is mostly working on improving stability |
| and reliability. |

| With this milestone build we introduce a new implementation of the supplementer |
| mechanism. This is an implementation change only, there are no changes required |
| by users of Equinox Aspects. This new implementation makes use of a new hook that |
| Equinox offers since 3.4. Therefore Equinox Aspects requires from now on Equinox 3.4. |

| <li>fixed: replace require-bundle with import-package for weaving.aspectj bundle (<a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=248046">bug 248046</a>)</li> |
| <li>fixed: change aspect activation from installed to resolved state (<a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=247718">bug 247718</a>)</li> |

| <b>More on OSGi dynamics for weaving services</b> |
| </td> |
| <td width="70%" valign="top"> |
| We are still struggling a bit with dynamically enabling the weaving service itself |
| and possibly re-weaving bundles that need aspect weaving from that point on time. |
| This works nicely in a standard OSGi setting but causes problems for RCP apps, |
| for example. We try to solve this within the M4 timeframe. Until those problems |
| are really solved, we have disabled the dynamics for the weaving service be default. |
| This makes it easy to use Equinox Aspects for general RCP apps or the IDE itself. |
| If you would like to enable the dynamics for the weaving service, you can set the |
| system property "equinox.weaving.service.dynamics=true". |
| <b>Note:</b> This has nothing to do with dynamics for aspect bundles. This is still |
| working nicely and enabled by default. |

| <b>Aspect bundles need to be resolved</b> |
| </td> |
| <td width="70%" valign="top"> |
| In the past aspects bundles were recognized by the system if the bundle was |
| installed. From now on aspect bundles need to be resolved before supplementing |
| or aspect information are taken into account by Equinox Aspects. This makes |
| dynamics of aspect bundles feel a lot more natural and OSGi-like. |

| We did some minor tweeks to the initialization of weaver objects to save |
| time for bundles that are loaded completely from the cache. The cache |
| is now very close to the performance of running without aspect weaving |
| at all. |
