In distro:911db8773e6a I made the availability of installers and packages more obvious. This comes from yet-another-ubuntu user faithfully following the InstallationGuide which hadn't been mentioning it.
I also updated the FoswikiReleaseViewTemplate to show a "Did you know..." tip just above the main download table. Not sure it's incredibly UX-tastic, but between these two things I hope people will be alerted to the existence of packages & installers.
Finally, I updated KnownIssuesOfFoswiki01x01 with issues for 1.1.5:
Item11929 Serious performance problem when deleting topics
Item12022 Log rotation is too slow, causes timeouts on busy sites at the end of month
Item11955 Configure fails with new RCS version, Argument "5.8.1" isn't numeric in numeric lt (<)
