This document describes the changes made to the Megaco 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 Megaco. Each release of Megaco thus constitutes one section in this document. The title of each section is the version number of Megaco.
Typos have been fixed.

A race condition when, during high load, processing both the original and a resent message and delivering this as two separate messages to the user.
Note that this solution only protects against multiple reply deliveries!

Various changes to configure and makefile(s) to facilitate cross compilation (and other build system improvements).
Own Id: OTP-8323
Added a help target in the test Makefile to explain the most useful make targets, used when testing the application using the test-server provided with megaco.
Own Id: OTP-8362
Adapted megaco_filter to the new internal format.

Callbacks, when the callback module is unknown (undefined), results in warning messages.
A race condition scenario. As part of a cancelation operation, replies with waiting acknowledgements is cancelled. This includes informing the user (via a call to the handle_trans_ack callback function). It is possible that at this point the connection data has been removed, which makes it impossible for megaco to perform this operation, resulting in the warning message. The solution is to also store the callback module with the other reply information, to be used when cleaning up after a cancelation.
