68. 53 3910 - Server is not authoritative over client environment when specified in an ENC -- Fixed in Telly
35 2198 - Install multiple package within a single call to the package manager -- Was patched against 0.24 and never merged
31 4409 - puppetmasterd does not find custom types for environment -- fixed in #13858
30 3741 - Custom facts loaded multiple times -- Fixed in telly
27 5517 - behavior change within 2.6 makes it impossible to override class parameters of "included" parametrized classes -- Early evaluation w/
'include foo' meant we need early evaluation with class { 'foo': }
27 2977 - Postgres backend for dashboard
27 10418 - Puppet agent hangs when listen is true and reading from /proc filesystem on redhat -- Tracked down to specific files in /proc like
mounts -- fixed in Facter 1.6.12.
26 8040 - Anchor pattern -- Graph should include containment relationships and not whits
26 5783 - Support HTTP(S) URL as the file 'source' -- No action
26 2247 - enablerepo and disablerepo for yum type -- dup of 4113 (provider-specific options)
24 1886 - Add node cleanup capability -- Complete
24 12173 - Masters cannot reliably distinguish between multiple versions of a type/function/plugin used in different environments -- Needs
process-per-environment.
23 5158 - File resources: Make source/content parameters and the file/template functions consistent. -- No action
