By changing to IEnumerable, it is possible to iterate only a portion of the list, which is useful when not all entries are needed (e.g., when testing a connection).
All existing backends have been updated, and any which were able to be changed to yield return results in a straightforward way now do.
Many backends had a try/catch in the List() method. Due to the fact that yield returns can't be placed within a try/catch block, these have been refactored to either scope the try/catch to the parts that (should) be the only places throwing exceptions, so that exceptions are still caught and handled.
Note that lazy evaluation may cause some changes in behavior - exceptions that were previously thrown at the point of invokation of List() may now be thrown while it is being enumerated.
I believe this will not be problematic though, as the only well-known exception seems to be FolderMissingException, which should be thrown by Test(), but TestList() attempts to enumerate the list to force this exception.
Any places that require the legacy behavior can get it by simply converting the lazy enumerable to a List()
InvariantCulture is useful when comparing / sorting human language strings in a culturely correct way. It handles things like accented letters in a way that makes sense to humans (e.g., 'a' should be sorted next to 'á', rather than after 'z').
Ordinal looks just at the raw code points of the characters. As such, it is recommended for use in cases when comparing system strings (file paths, command line parameters, config settings, etc.). Since it doesn't need to use the culture specific sorting rules, this method can often be faster.

Status: Fixed
Duplicati is now using the AWSSDK library, which apparently handles buckets with periods just fine. The validation is now performed by the AWSSDK library so it is most likely correctly validating bucket names.

Status: Fixed
Changed to the AWSSDK library, which fixes a few quirks, but basically seems to be the Affirma version slightly renamed.

Fixed issue #215.
If the user chooses EU buckets, bucketnames that are not valid hostname labels will be rejected.
If the user does not choose EU buckets, a warning is displayed for bucketnames that are not valid hostname labels, and the setup is switched to the path-style calling method.
Fixed issue #214.
There were multiple issues with entering a bucket/folder type path, those should now be resolved.
Fixed issue #212.
The UI and commandline now supports Reduced Redundancy Storage.

This was based on the idea that the interfaces should remain static.
I hope this change is enough to ensure stable interfaces until release 1.2.
Overview of changes:
Moved all interfaces into the same dll.
Encryption and compression is now plugable modules, just as the backends.
Encryption/compression can now register an UI.
Encryption now uses AESCrypt as a default.
GPG does not default to using the --armor option.
Added support for generic modules, but none are written yet.
Added support for plugable settings pages in the "Options" dialog.
Fixed issue #148.
Duplicati now uses AESCrypt as the default encryption format.
Fixed issue #199.
GPG now supports custom commandline options.
Fixed issue #207.
Encryption modules are now plugable.
Fixed issue #118.
S3 credentials are now stored.
Fixed issue #151.
Backends can now register system wide options.

I am unable to reproduce the error with the "test connection" that you describe.
Was it with a particular bucket/folder name?
I have also added some logic to ensure that it does not repeatedly ask to prefix the username.

Fixed#12, signature cache, which is now enabled pr. default.
Added a cache for the S3 redirect tests, which should limit the number of calls.
Added some GC.Collect calls for the S3 backend, as it appears to be leaking HttpWebRequest objects for some reason.
