| Apache BSF 3 Beta3 Release Notes |
| -------------------------------- |
| |
| Apache BSF 3 is an open-source implementation of JSR-223, |
| "Scripting for the Java Platform". |
| |
| *----------------------------------------------------------------------* |
| * BSF3 was developed according to the JSR-223 specs, but has not yet * |
| * been tested via the JSR-223 TCK. BSF can therefore not be considered * |
| * a compatible implementation of JSR-223. * |
| *----------------------------------------------------------------------* |
| |
| However, the implementation is believed to be complete. |
| |
| * BSF-3.0 is not compatible with BSF-2.4 - the API is completely different. |
| * BSF-3.0 can be deployed and used on Java 1.4+ - it does not require Java 1.6 |
| |
| Incomplete packages |
| ------------------- |
| The org.apache.bsf.utils.http and org.apache.bsf.xml packages contain several classes. |
| These are not complete, and should not be relied on. |
| They are not needed in order to use the javax.script API. |
| |
| Changes from previous releases |
| ------------------------------ |
| |
| This 3.0-beta3 release is a maintenance release update to support the latest releases |
| of various script language engines. |
| |
| The classes in the javax.script package have been overhauled to align the API, Javadoc and |
| the behaviour with the JSR-223 spec, and several unit tests have been added. |
| |
| Some of these changes may cause problems for programs that have been written to the BSF 3.0 |
| Javadoc rather than the JSR-223 spec. |
