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.</p> <section><title>Megaco 3.17.0.1</title> <section><title>Improvements and New Features</title> <list> <item> <p> Postscript files no longer needed for the generation of PDF files have been removed. </p> <p> Own Id: OTP-11016</p> </item> </list> </section> </section> <section><title>Megaco 3.17</title> <p>Version 3.17 supports code replacement in runtime from/to version 3.16.0.3 and and 3.16.0.2. </p> <section> <title>Improvements and new features</title> <p>-</p> <!-- <list type="bulleted"> <item> <p>Allow whitespaces in installation path. </p> <p>It is now possible to give configure and make an installation/release path with whitespaces in it. </p> <p>Own Id: OTP-10107</p> </item> </list> --> </section> <section> <title>Fixed bugs and malfunctions</title> <!-- <p>-</p> --> <list type="bulleted"> <item> <p>Buffer overrun error while flex scanner processing property parm groups. </p> <p>This error occured only for large messages if a buffer realloc was needed while processing the property parm groups. </p> <p>Own Id: OTP-10998</p> <p>Aux Id: Seq 12263</p> </item> </list> </section> <section> <title>Incompatibilities</title> <p>-</p> <!-- <list type="bulleted"> <item> <p>A number of binary encoding alternatives has been removed.

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. </p> <p>Own Id: OTP-8328</p> <p>Aux Id: Seq 11384</p> </item> </list> </section> </section> <!-- 3.14 --> <section> <title>Megaco 3.13</title> <p>Version 3.13 supports code replacement in runtime from/to version 3.12 and 3.11.3.</p> <section> <title>Improvements and new features</title> <!-- <p>-</p> --> <list type="bulleted"> <item> <p>A minor optimization by using ets:update_element instead of ets:insert for some table updates.</p> <p>Own Id: OTP-8239</p> <!-- <p>Aux Id: Seq 11332</p> --> </item> <item> <p>The documentation is now built with open source tools (<em>xsltproc</em> and <em>fop</em>) that exists on most platforms.
