The developers of the open-source Docker Linux container engine for GNU/Linux operating systems have published the first maintenance release of the Docker 1.9 stable branch.
If you’re reading the news lately, you would know that the Docker 1.9 release was a massive one, introducing an enormous amount of new features that propelled the project forward.
This past weekend, Docker 1.9.1 was made available for download after being in development for the last two weeks, during which it received a single Release Candidate (RC) version.
Looking at the changelog, attached at the end of the article for reference, Docker 1.9.1 is mostly a bugfix release that promises to resolve some of those nasty bugs reported by users since the previous stable version of the software.
What’s new in Docker 1.9.1
Among the most important things brought by Docker 1.9.1, we can mention support for relabeling SELinux only if it is requested by the user with the ‘z’ option, as well as support for correctly displaying a devicemapper file system in the Docker info.
Network calls will no longer be made when the names are being normalized, seldom panics was fixed, a regression with the performance of the Docker stats was resolved, and IPC unmount errors are now turned into warnings.
Moreover, a regression with symlink behavior in the builder has been fixed, Docker can now pass network IDs as an argument for the ‘–net’ option, and the Docker login now functions properly on Microsoft Windows operating systems.
Last but not least, deterministic IPv6 generation is now being restored from MAC addresses on default bridge network, port-mapping is only allowed for endpoints generated when executing the “docker run” command.
Of course, numerous other issues have been fixed as well in the new Docker 1.9 maintenance release, so we recommend checking the changelog below for more details. In the meantime, you can download Docker 1.9.1 right now from Softpedia.
