ns-allinone-3.46.1 released
A new ns-allinone release, following the October ns-3.46.1 release has been published. The ns-allinone release series bundles compatble extension modules with the mainline ns-3 release. This release includes fifteen compatible contributed modules, including five newly added modules and one (wimax) that was migrated from the ns-3 mainline. Contributed modules are separately maintained ns-3 extensions that are advertised in the ns-3 App Store, and we plan to bundle those modules that are compatible with the release in an allinone release approximately one month after the mainline release.
