Jump to: navigation, search

On September 18, 2019, ns-3.30.1 was published. This provided a hotfix to the wifi module (for which a performance regression had been reported) and a maintenance update for the latest clang compiler being planned for macOS 10.15. More details are available in the RELEASE_NOTES. Users who previously downloaded and started working on the ns-3.30 release may try a patch upgrade with the ns-3.30.1 changes.

The following issues and mitigations have been reported on ns-3.30 since the September 18 release of ns-3.30.1:

This issue is being worked on, hopefully to be remedied in a forthcoming ns-3.30.2 maintenance update.

Gabriel Ferreira reported that this is an upstream bug with WSLv1: https://github.com/microsoft/WSL/issues/830

He reported that WSLv2 fixes it, but is slower than WSLv1 for CPU-intensive applications.
