RELEASE NOTES



	version 1.3-beta:

		- Updates the base64 utilities and junit to their newest versions.

		- Has better text on the web application's index page for the Oracle

		  IAS/OC4J server and for Jetty.

		- Fixes access permissions and JSP syntax for JBoss 4.0.2. (thanks to

		  Pablo Barrionuevo)

		- Now uses the internal JBoss MBean server if deployed a JBoss server.

		  This means that you can see all MBeans that JBoss exposes, not just

		  the platform MBeans.

		- Adds a whilelist feature to regulate what hosts or IP addresses can

		  and cannot connect to the Zapcat agent. (thanks to Tim McCune)



	version 1.2:

		- Introduces a trapper that can push data into the Zabbix server.

		- Fixes an issue where system properties would be ignored by agents

		  during startup. Hard-coded configuration was removed to simplify the

		  agent's interface.

		- Now works with older versions of Zabbix by introducing a switch that

		  allows you to select the Zabbix 1.4 protocol, or the Zabbix 1.1

		  protocol. (thanks to Valeri Felberg) Note that there are some issues

		  with the trigger expression parser in Zabbix 1.1. I have not tested

		  this very well, because I use Zabbix 1.4.

		- Has some unit tests to avoid regression (never enough, though).

		- Introduces a template for Java applications, making it even easier to

		  quickly set up a monitor.

		- Introduces a template for Hibernate, allowing you to track down SQL

		  query storms and database connection leakage.

		- Introduced a template for Tomcat, plus a host definition generator to

		  automatically generate a host definition tailored to your Tomcat

		  configuration.

		- Makes the agent reply with ZBX_NOTSUPPORTED for unsupported mbeans or

		  attributes. This makes the logging a lot less verbose and makes it

		  easier to see what the Zapcat agent supports and what not. This is

		  largely thanks to Gerco Dries, who documented the agent protocol on

		  the Zabbix wiki.

		- Introduces agent.version and agent.ping.

		- Makes the agent more robust against query formatting errors.



	version 1.1:

		- Introduces an Openfire XMPP server plugin for Zapcat. (thanks to Guus

		  der Kinderen)

		- Fixes a problem where the agent closed the connection before the

		  Zabbix server had time to send the query.

		- Updates to a newer version of Log4J. (thanks to Guus der Kinderen)

		- Changes the query parser so that square brackets in object names are

		  no longer a problem.

		- Updates the server socket to use NIO. (thanks to Guus der Kinderen)

		- Introduces a servlet for easy integration in servlet containers, such

		  as Tomcat.

		- Introduces a system property to configure the bind address. (thanks

		  to Guus der Kinderen)



    version 1.0:

		- First version. Supports Zabbix agents and composite data.
