| <p> |
| This release is primarily a bug fix and performance / memory usage release. |
| Over 70 fixes and enhancements have been incorporated since 1.5.0, you can see |
| the list through |
| <a href="https://bugs.eclipse.org/bugs/buglist.cgi?query_format=advanced&product=AspectJ&target_milestone=1.5.1&bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED"> |

| AspectJ 1.5.1 has significantly lower memory usage than AspectJ 1.5.0, |
| especially when building inside of AJDT. The improvements are also noticeable |
| when batch building with Ant, or when load-time weaving. Batch building a |
| project with over 1000 source files with both AspectJ 1.5.1 and AspectJ 1.5.0 |
| shows a 16% reduction in peak memory usage, and an 8% reduction in heap consumed |
| by temporary objects. The AspectJ 1.5.1 compiler integrated into AJDT gives memory |
| savings of at least 50%. The greater savings in the AJDT environment are due to |
| improvements in areas such as structure model generation that are not exercised |
