This release fixes some bugs in the permission checking when responding to incoming connections to the IBC command server.
Part of this was addressed in issue #44 and PR #43 (thanks to @nickles). But there was also a bug in the procedure for checking whether the connecting address is in the list of permitted addresses.
Some trivial changes have been made to the 'Overview of IBC' section in the User Guide's introduction.
You only need to update your IBC installation if you make use of IBC's command server. If you have already installed IBC 3.7.0 thru 3.7.4, you can just extract the IBC.jar file from the zip to your IBC folder, replacing the existing file. You should also do the same with the version file, to ensure that IBC log files contain the correct information.
