         - `configuration:` optional configuration path, which the plugin can use to read/write it's configuration file.
 
   2. Let plugins add Pipelines the same way they can add Handlers, Rules etc...

+    - [<s>MR !287</s> merged](https://gitlab.com/mailman/mailman/merge_requests/287)
     - This means refactoring `BasePipeline`, `OwnerPipeline`, `PostingPipeline`, `VirginPipeline` from `mailman.core.pipelines.py` into a package `mailman.pipelines`
     - Use `find_components`, or rather it's sibling function created in 1.

   4. Allow multiple callables in `pre_hook` and `post_hook` run in order specified. Also allow callables for when Mailman exits.

   5. Allow Mailman core to send events to Postorius, HyperKitty and any app that subscribes through a new REST api call with a callback.
-    - Also add an `IEvent` interface, as currently events don't implement any interface at all.
+    - Implemented in the [mailman-rest-events](https://gitlab.com/J08nY/mailman-rest-events) plugin.
 
   6. Drop `ext_dir`.

   9. Add `description` attribute to `IStyle` and the default styles, so that mailing list styles have some human readable string to show.

-  9. ? Make all commands be able to require confirmation and make this a configurable option.
-    - How?
-    - Abstract out confirmation of commands (is actually almost there with Pendables)
-    - Add another field to `MailingList` model, for a list of commands that require confirmation for that list?
+ 10. Refactor Subscription and Unsubscription workflow to allow a plugin to add steps to it's state machine.
+    - Introduces `IWorkflow` interface for the workflow state machine.
+    - Allows the `WorkflowStateManager` to store more workflow steps than the current one and adds a migration for this change.
+    - Refactors the monolithic SubscriptionWorkflow and UnsubscriptionWorkflow classes to reusable mixins, allowing to deduplicate their code and create custom workflows.
+    - Dynamically loads all `IWorkflow` classes from Mailman core and plugins.
+    - Migrates the `subscription_policy` and `unsubscription_policy` attributes from the `SubscriptionPolicy` enum, to store the name of the respective SubscriptionWorkflow class, dynamically loaded.

+    - On top of [MR !300](https://gitlab.com/mailman/mailman/merge_requests/300) which instantiates components only in the `add_components` utility function and not at lower levels, since Workflow components need to be stored as classes and instantiated on use.
 
-  10. ?? Add a new attribute to several core models (MailingList, User, Address, ...) in which plugins can store metadata about said objects. This attribute woul be a PickleType, really a dict with, plugin-names as keys. Each plugin could access its and only its metadata attached to a given object.
+  11. Add SMTPS and STARTTLS support.
+    - Adds SMTP over SSL/TLS and STARTTLS SMTP extension support to the `BaseDelivery` class via specialized `Connection` classes.
+    - Creates a new `ISMTPConnection` interface, which `SMTPConnection`,`SMTPSConnection` and `STARTTLSConnection` implement.
