- Added google_storage_* keys - Fixed indentations. - Factored out requires and recognizes method implementation (now relies on the requires and recognizes clause from the NamedParameters module) - Added dependency to named-parameters gem. - Added recognizes declaration to classes for all supported services to enforce parameter name checks - - passing an unrecognized key when instantiating a service object will now cause an ArgumentError to be raised. - Added NOTE - comment added - check/filter-out keys from credentials that are not required by the class being instantiated - [local|storage] properly write out file contents - Added google_storage_* keys - Fixed indentations. - added put_object_acl request (ref: https://github.com/geemus/fog/issues#issue/74) - Release 0.3.24 - remove tracker reference from README - issues is now the goto for bugs/todo - notify and gracefully skip credential-less testsa - [rackspace|storage] fixes for directory/files - [local|storage] CGI.escape file names - Release 0.3.25 - updated deps; recognized_parameters -> declared_parameters; restored options filtering if Fog.bin - Added requires/recognizes to Fog::Terremark::Ecloud - Updted to use latest named-parameters gem. - Filter out unwanted parameters when Fog.bin - Updated to latest named-parameters gem - commented out unnecessary code - fix missing "volume" parameter error when setting Fog::AWS::Volume#server to nil (in order to detach it) - documentation update for key_pairs and helper - [aws|compute] commented/documented flavors/volumes - Fixes for issue 38 and 39 Closes #96
