-## :pleroma_job_queue
+## Oban

-[Pleroma Job Queue](https://git.pleroma.social/pleroma/pleroma_job_queue) configuration: a list of queues with maximum concurrent jobs.
+[Oban](https://github.com/sorentwo/oban) asynchronous job processor configuration.
+
+Configuration options described in [Oban readme](https://github.com/sorentwo/oban#usage):
+* `repo` - app's Ecto repo (`Pleroma.Repo`)
+* `verbose` - logs verbosity
+* `prune` - non-retryable jobs [pruning settings](https://github.com/sorentwo/oban#pruning) (`:disabled` / `{:maxlen, value}` / `{:maxage, value}`)
+* `queues` - job queues (see below)

 Pleroma has the following queues:

+* `activity_expiration` - Activity expiration
 * `federator_outgoing` - Outgoing federation
 * `federator_incoming` - Incoming federation
-* `mailer` - Email sender, see [`Pleroma.Emails.Mailer`](#pleroma-emails-mailer)
+* `mailer` - Email sender, see [`Pleroma.Emails.Mailer`](#pleromaemailsmailer)
 * `transmogrifier` - Transmogrifier
 * `web_push` - Web push notifications
-* `scheduled_activities` - Scheduled activities, see [`Pleroma.ScheduledActivities`](#pleromascheduledactivity)
+* `scheduled_activities` - Scheduled activities, see [`Pleroma.ScheduledActivity`](#pleromascheduledactivity)

 Example:

 ```elixir
-config :pleroma_job_queue, :queues,
-  federator_incoming: 50,
-  federator_outgoing: 50
+config :pleroma, Oban,
+  repo: Pleroma.Repo,

+  prune: {:maxlen, 1500},
+  queues: [
+    federator_incoming: 50,
+    federator_outgoing: 50
+  ]
 ```

-## Pleroma.Web.Federator.RetryQueue
+### Migrating `pleroma_job_queue` settings

-* `enabled`: If set to `true`, failed federation jobs will be retried
-* `max_jobs`: The maximum amount of parallel federation jobs running at the same time.
-* `initial_timeout`: The initial timeout in seconds
-* `max_retries`: The maximum number of times a federation job is retried
+`config :pleroma_job_queue, :queues` is replaced by `config :pleroma, Oban, :queues` and uses the same format (keys are queues' names, values are max concurrent jobs numbers).
+
+### Note on running with PostgreSQL in silent mode
+
+If you are running PostgreSQL in [`silent_mode`](https://postgresqlco.nf/en/doc/param/silent_mode?version=9.1), it's advised to set [`log_destination`](https://postgresqlco.nf/en/doc/param/log_destination?version=9.1) to `syslog`, 
+otherwise `postmaster.log` file may grow because of "you don't own a lock of type ShareLock" warnings (see https://github.com/sorentwo/oban/issues/52). 
+
+## :workers
+
+Includes custom worker options not interpretable directly by `Oban`.
+
+* `retries` — keyword lists where keys are `Oban` queues (see above) and values are numbers of max attempts for failed jobs.
+
+Example:
+
+```elixir
+config :pleroma, :workers,
+  retries: [
+    federator_incoming: 5,
+    federator_outgoing: 5
+  ]
+```

+### Migrating `Pleroma.Web.Federator.RetryQueue` settings

+* `max_retries` is replaced with `config :pleroma, :workers, retries: [federator_outgoing: 5]`
+* `enabled: false` corresponds to `config :pleroma, :workers, retries: [federator_outgoing: 1]`

 * `:statuses_actions` for create / delete / fav / unfav / reblog / unreblog actions on any statuses
 * `:status_id_action` for fav / unfav or reblog / unreblog actions on the same status by the same user
+
+## :web_cache_ttl
+
+The expiration time for the web responses cache. Values should be in milliseconds or `nil` to disable expiration.
+
+Available caches:
+
+* `:activity_pub` - activity pub routes (except question activities). Defaults to `nil` (no expiration).
+* `:activity_pub_question` - activity pub routes (question activities). Defaults to `30_000` (30 seconds).

+
+  To enable the cache add the plug to a router pipeline or controller:
+
+      plug(Pleroma.Plugs.Cache)
+
+  ## Configuration
+
+  To configure the plug you need to pass settings as the second argument to the `plug/2` macro:
+
+      plug(Pleroma.Plugs.Cache, [ttl: nil, query_params: true])
+
+  Available options:
+
+  - `ttl`:  An expiration time (time-to-live). This value should be in milliseconds or `nil` to disable expiration. Defaults to `nil`.
+  - `query_params`: Take URL query string into account (`true`), ignore it (`false`) or limit to specific params only (list). Defaults to `true`.
+  - `tracking_fun`: A function that is called on successfull responses, no matter if the request is cached or not. It should accept a conn as the first argument and the value assigned to `tracking_fun_data` as the second.
+
+  Additionally, you can overwrite the TTL inside a controller action by assigning `cache_ttl` to the connection struct:
+
+      def index(conn, _params) do
+        ttl = 60_000 # one minute
