Release Notes: This release fixes a risk of a crash introduced with 1.3.19 for configurations in which a timeout is missing, as the result of an incomplete bugfix. While it is strongly recommended to avoid such configurations, they should not cause such issues. A minor issue with TCP logging has also been fixed. No new features were added. All users of versions 1.3.16 to 1.3.19 are strongly encouraged to upgrade. Development version 1.4-dev2 has also been released with the same fixes.
