Version 0.3.0 (Jun 2016)

Objects at run time are now partitioned according to the labels of their fields. This allows workers to read/modify an object's field without needing to be also trusted to read/modify the rest of the object.
Various bug fixes, including:
- Constraints on main() are now checked at run time.
- The length field of array type T{L}[] is now labelled L instead of this.
- Fixed a command-line processing bug that resulted in robustness checks being turned off by default. This bug affects all Fabric 0.2.x releases.
Updated to Jif 3.5.0 and Polyglot 2.7.1.

Version 0.2.2 (Jul 2014)

Language support for specifying the access policy for a class or interface independently from fields.
Support for local deadlock detection.
SIF has been refactored to better support building non-HTML web apps.
Class hashing is now less sensitive to the version of Java being used.
Various bug fixes and performance improvements.
Updated to Jif 3.4.2 and Polyglot 2.6.1.

Issued fresh node certificates for examples. The old ones had expired.

Workers have interactive consoles. These can be used to run Fabric programs or invoke the Fabric compiler from within the worker.
Workers listen for administrative connections. If a second instance of a worker is launched, it will attach to the first instance on the administrative port and execute commands within the first instance. This is a convenience feature to enable scripting of worker commands.
Added DummyFetchManager, which implements a degenerate dissemination layer.
Added bin/dump-bdb, which dumps the contents of a store's BDB-backed object database
Various performance improvements.
