## 2. Compatibility with Previous Release

API Contract Compatibility: GEF 3.0 is upwards contract-compatible with GEF 2.1 except where the Eclipse Platform . Downward contract compatibility is not supported. There is no guarantee that compliance with 3.0 APIs would ensure compliance with 2.1 APIs. Refer to Evolving Java-based APIs for a discussion of the kinds of API changes that maintain contract compatibility.

Binary (plug-in) Compatibility: GEF 3.0 is upwards binary-compatible with GEF 2.1 except in those areas noted in the Eclipse 3.0 Plug-in Migration Guide. Eclipse 3.0 will include additional runtime compatibility mechanisms to provide effective binary API compatibility. Downward plug-in compatibility is not supported. Plug-ins for Eclipse SDK 3.0 will not be usable in Eclipse SDK 2.0 or 2.1. Refer to Evolving Java-based APIs for a discussion of the kinds of API changes that maintain binary compatibility.

Non-compliant usage of API's: All non-API methods and classes, and everything in a package with "internal" in its name, are considered implementation details which may vary between operating environment and are subject to change without notice. Client plug-ins that directly depend on anything other than what is specified in the API are inherently unsupportable and receive no guarantees about compatibility within a single release or across releases. Refer to How to Use the Eclipse API for information about how to write compliant plug-ins.

## 3. Known Issues

#### Win32 - Printing

> Some fonts scale differently on the printer than they do on the screen. This may result in printed text appearing wider than the same text on the screen. This is only a problem with certain vector fonts.

> Images with transparency masks may print incorrectly. This is a limitation in SWT, which GEF uses for printing.

> Printing is not implemented on some SWT platforms.
