Using bone meal usually grows flowers specific to the biome, like Blue Orchids in Swamplands, but in Swampland M only Poppies and Dandelions grow. I'm not sure if this is intentional or an error.

Please reopen the ticket. It is still a bug (or a feature?) in the current version.
Working in the biome many days and slimes are also not spawning. This is listed in the en-Wiki: http://minecraft.gamepedia.com/Swampland#Swampland (better say: Slimes are not in the feature's list)
This needs another issue report, does it?
That is a separate issue and is probably due to the phase of the moon during the time you tested.
Is this still a concern in the current Minecraft version 1.7.2 / Launcher version 1.3.4 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
