"build/site" is now copied to "docs".
The build directory isn't included in either distribution anymore.
Source distribution doesn't contain fop.jar, javadocs and compiled docs anymore to make the distribution smaller.
KEYS and status.xml and lib/xalan*.txt added (Thanks, Simon).
Added version info to javadocs.
Removed limitation to build javadocs only with JDKs >= 1.4. It works fine for me on Win32 Sun JDK 1.3.1_15.
You can add "javahome.jdk14" to your build-local.properties so Forrest docs can be built during a JDK 1.3 distribution build.
Added release notes to site (Thanks, Christian, for the reminder).
