Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Default value for the welcome / bye notification is now set to false The mailframe checkbox now primarily toggles the mail opening, however if you hold shift you can still disable the entire addon Now properly removes QuickAuction?s mail count Now tracks when a mail lost all attachments rather than it being deleted in order to continue processing the next item (mail sent by players containing text should now work properly). This should also be good for a nice speed increase. Added a variable called ?busy? to the MailOpener object indicating whether or not Mail Opener is currently working. Other addons (or macros) can retrieve it with ?LibStub("AceAddon-3.0"):GetAddon("MailOpener").busy? A mail refresh from the Postal service should no longer occur while mail is being opened but will happen instantly afterwards. Postal?s module toggling will now be handled by Postal itself. Added a short summary to the top of all modules for other developers. The time remaining until next mail box refresh should be displayed for as long as Mail Opener can be sure.

Zerotorescue@0 1 --- **AceDB-3.0** manages the SavedVariables of your addon.
Zerotorescue@0 2 -- It offers profile management, smart defaults and namespaces for modules.\\
Zerotorescue@0 3 -- Data can be saved in different data-types, depending on its intended usage.
Zerotorescue@0 4 -- The most common data-type is the `profile` type, which allows the user to choose
Zerotorescue@0 5 -- the active profile, and manage the profiles of all of his characters.\\
Zerotorescue@0 6 -- The following data types are available:
Zerotorescue@0 7 -- * **char** Character-specific data. Every character has its own database.
Zerotorescue@0 8 -- * **realm** Realm-specific data. All of the players characters on the same realm share this database.
Zerotorescue@0 9 -- * **class** Class-specific data. All of the players characters of the same class share this database.
Zerotorescue@0 10 -- * **race** Race-specific data. All of the players characters of the same race share this database.
Zerotorescue@0 11 -- * **faction** Faction-specific data. All of the players characters of the same faction share this database.
Zerotorescue@0 12 -- * **factionrealm** Faction and realm specific data. All of the players characters on the same realm and of the same faction share this database.
Zerotorescue@0 13 -- * **global** Global Data. All characters on the same account share this database.
Zerotorescue@0 14 -- * **profile** Profile-specific data. All characters using the same profile share this database. The user can control which profile should be used.
Zerotorescue@0 15 --
Zerotorescue@0 16 -- Creating a new Database using the `:New` function will return a new DBObject. A database will inherit all functions
Zerotorescue@0 17 -- of the DBObjectLib listed here. \\
Zerotorescue@0 18 -- If you create a new namespaced child-database (`:RegisterNamespace`), you'll get a DBObject as well, but note
Zerotorescue@0 19 -- that the child-databases cannot individually change their profile, and are linked to their parents profile - and because of that,
Zerotorescue@0 20 -- the profile related APIs are not available. Only `:RegisterDefaults` and `:ResetProfile` are available on child-databases.
Zerotorescue@0 21 --
Zerotorescue@0 22 -- For more details on how to use AceDB-3.0, see the [[AceDB-3.0 Tutorial]].
Zerotorescue@0 23 --
Zerotorescue@0 24 -- You may also be interested in [[libdualspec-1-0|LibDualSpec-1.0]] to do profile switching automatically when switching specs.
