| Release notes for Commons-Pool 2.0 |
| =================================== |
| There were a lot changes since the 1.0.1 release on 12 Aug 2002. |
| * A lot of corner cases were fixed |
| |
| * Performance improvement by optimizing pool synchronization, |
| the critical code paths were optimized by reducing pool synchronization |
| but we also added more synchronization where needed |
| |
| * New minIdle feature: the minimum number of objects allowed in the pool |
| before the evictor thread (if active) spawns new objects. |
| (Note no objects are created when: numActive + numIdle >= maxActive) |
| |
| * New maxTotal feature: a cap on the total number of instances controlled by a pool. |
| Only for GenericKeyedObjectPool where maxActive is a cap on the number of active |
| instances from the pool (per key). |
| |
| * UML Class & sequence diagrams |
| |
| * The following issues were resolved: (see Bugzilla for complete description) |
