1 Event Tracer (ET) Release Notes
This document describes the changes made to the Event Tracer (ET) system from version to version. The intention of this document is to list all incompatibilities as well as all enhancements and bugfixes for every release of Event Tracer (ET). Each release of Event Tracer (ET) thus constitutes one section in this document. The title of each section is the version number of Event Tracer (ET).
The scroll bar of the et_viewer window could not be dragged all the way to the top of the window. It would always stop at the second event. This is now corrected.

Application upgrade (appup) files are corrected for the following applications:
asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl
A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.

*** POTENTIAL INCOMPATIBILITY ***

Thanks to Olle Mattsson the GUI parts are rewritten to use wxWidgets. For the time being it is still possible to use the old GS based version of the tool, but it is deprecated. The wxWidgets based version is started by default.
A print function has been added, in order to enable printing of sequence charts.
A new tutorial has been added to the documentation. It is based on Jayson Vantuyl's article http://souja.net/2009/04/making-sense-of-erlangs-event-tracer.html.
The functions et:trace_me/4 and et:trace_me/5 has been introduced in order to replace the deprecated functions et:report_event/4 and et:report_event/5. Hopefully the new names makes it a little more obvious what the intended usage of the functions are.
The max_events configuration parameter to et_viewer is not used any more. Now the event cache in the Viewer only contains those events that actually are displayed in the GUI.
Own Id: OTP-8058
The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the HTML frames are removed.
