<h2>Version 0.3</h2>
</a>
<h3>What's new?</h3>
<dl>
<dt>Cooperative Concurrency</dt>
<dd>Support for concurrent request handling and method invocation by the use of co-routines implemented by Lua. See demo 'concurrency' for more details.</dd>
<dt>Customization</dt>
<dd>Better module organization enabling the use of reduced versions of OiL. See demo 'minimal' for more details.</dd>
<dt>Dynamic Adaptaion</dt>
<dd>Support for ORB adaptation due to changes on interface definitions. See demo 'adapt' for more details.</dd>
<dt>Remote Interface Repository</dt>
<dd>Support for retrieving interface definitions from a remote IR. Use the operations <code>oil.setIR(ir)</code> and <code>oil.getIR()</code> to define the remote IR to be used.</dd>
<dt>Integrated Interface Repository</dt>
<dd>All definitions handled by OiL are accessible though the IR interfaces of CORBA. Use operation <code>oil.getLIR()</code> to get a reference for the integrated IR</dd>
<dt>Interface Probing Operations</dt>
<dd>Objects exported by OiL implement the operations <code>_is_a</code> and <code>_interface</code> for probing object interface definitions.</dd>
<dt>Absolute Name Support</dt>
<dd>Support for the use of interface absolute name on <code>oil.newproxy</code>, <code>oil.newobject</code> and <code>oil.narrow</code> operations.</dd>
<dt>Explicit ORB Initialization</dt>
<dd>OiL Main ORB can be explicitly initialized by the operation <code>oil.init(config)</code>. However, it is still implicitly initialized at invocation of oil.newproxy or oil.newobject operations.</dd>
<dt>Pre-Compiled Libraries</dt>
<dd>Makefiles can create a library with all Lua scripts precompiled, so it can be embedded into applications or dynamically loaded using the package model of Lua 5.1.</dd>
<dt>IOR File Operations</dt>
<dd>Addition of operations for reading and writing IOR stored in files.</dd>
<dt>Lua 5.1 alpha</dt>
<dd>Conformance to Lua 5.1 alpha</dd>
</dl>
<h3>What changed?</h3>
<dl>
<dt>Operation _get_ior</dt>
<dd>Changed to _ior to avoid name conflict with a possible attribute named 'ior'.</dd>
<dt>Get stringfied IOR</dt>
<dd>Should be oil.ior.encode(objref) instead of oil.ior.encode(objref._ior).</dd>
