Some places in Asterisk did not treat the formats on a stream as immutable when they are. The ast_stream_get_formats function is now const to enforce this and parts of Asterisk have been updated to take this into account. Some violations of this were also fixed along the way. An additional minor tweak is that streams are now allocated with an empty format capabilities structure removing the need in various places to check that one is present on the stream.

DO NOT REMOVE THIS FILE!
The only files that should be added to this directory are ones that will be used by the release script to update the UPGRADE.txt file automatically. The only time that it is necessary to add something to the UPGRADE-staging directory is if you are making a breaking change to an existing feature in Asterisk. The file does not need to have a meaningful name, but it probably should. If there are multiple items that need documenting, you can add multiple files, each with their own description. If the message is going to be the same for each subject, then you can add multiple subject headers to one file. The "Subject: xxx" line is case sensitive! For example, if you are making a change to PJSIP, then you might add the file "res_pjsip_my_cool_feature.txt" to this directory, with a short description of what it does. The files must have the ".txt" suffix. If you are adding multiple entries, they should be done in the same commit to avoid merge conflicts. Here's an example:
Subject: res_pjsip Subject: Core
Here's a pretty good description of my new feature that explains exactly what it does and how to use it.
Here's a master-only example:
Subject: res_ari Master-Only: True
This change will only go into the master branch. The "Master-Only" header will never be in a change not in master.
Note that the second subject has another header: "Master-Only". Changes that go into the master branch and ONLY the master branch are the only ones that should have this header. Also, the value can only be "true" or "True". The "Master-Only" part of the header IS case-sensitive, however!
