We will use bugzilla to track bug priorities (esp. P1 blocker bugs) for the next release.

The main difference is that the bake build system is planned to be added, to support inclusion of Direct Code Execution project.

Bugs being worked

We will use bugzilla to track bug priorities (esp. P1 blocker bugs) for the release.

Current blockers:

• bug 1658 (documentation for bake)
• bug 1657 (bake)
• bug 1651 (DSR documentation of changes)
• bug 1650 (LTE documentation of changes)
• bug 1649 (bindings for fd-net-device)
• bug 1639 (bake)
• bug 1637 (bake)
• bug 1636 (bake)
• bug 1622 (apiscan)

Also, need to fix bug 1644 although we could probably release with it by changing the example:

• bug 1644 (flow monitor valgrind)

Also, bindings scanning depends on this, which may be resolved already by latest git repository version of gccxml (need to confirm):

• bug 1530 (apiscan)

Bugs in ns-3 models

Open bugs will be worked on a best-effort basis.
