• each task in the configuration file now has its own requirements entry in the run subsection which takes precedence over the requirements listed in the GENERAL section. This enables users to have different versions of the same requirements for different tasks.

• added support for floating point memory requests.

• made all the merged files to store in a directory called merge.

• username and version are automatically added to the config files when using make_config command.

• added a check to make sure that the input of the implicit merge node is always a list.
