+
+ * camel-store.[ch]: Reorganize the folder-fetching methods and
+ implement a folder cache so that multiple requests for the same
+ folder will yield the same CamelFolder object (as long as it
+ remains active). Includes some code to remove no-longer-active
+ folders from the cache, but it doesn't get used since nothing is
+ ever unref'ed in Camel right now...
+
+ * providers/mbox/camel-mbox-store.c:
+ * providers/pop3/camel-pop3-store.c: update for CamelStore
+ changes.
+
+ * camel-folder.[ch]: Remove the (unused) CamelException argument
+ from camel_folder_get_name and camel_folder_get_full_name.
+ (camel_folder_set_name): make this go away since changing a
+ folder's name after it has been created could result in it
+ conflicting with a separately-issued folder.
+
2000-04-05 Dan Winship <danw@helixcode.com>
* g_url_new really wanted to take a CamelException. So, rename
