 ## Currently Active Work Areas
 For each release cycle of Reticulum, improvements and additions from the five [Primary Efforts](#primary-efforts) are selected as active work areas, and can be expected to be included in the upcoming releases within that cycle. While not entirely set in stone for each release cycle, they serve as a pointer of what to expect in the near future.
 
-- The current `0.5.x` release cycle aims at completing
-  - [x] Reach feature-completion of the Reticulum API
-  - [x] Improve performance and efficiency of the `Buffer` and `Channel` API
+- The current `0.6.x` release cycle aims at completing
   - [ ] Overhauling and updating the documentation
-  - [ ] Performance and memory optimisations of the Python reference implementation
-  - [ ] Fixing potential bugs
+  - [ ] Distributed Destination Naming System
+  - [ ] Create a standalone RNS Daemon app for Android
+  - [ ] Network-wide path balancing
   - [ ] Add automatic retries to all use cases of the `Request` API
+  - [ ] Performance and memory optimisations of the Python reference implementation
+  - [ ] Fixing bugs discovered while operating Reticulum systems and applications
 
 ## Primary Efforts
 The development path for Reticulum is currently laid out in five distinct areas: *Comprehensibility*, *Universality*, *Functionality*, *Usability & Utility* and *Interfaceability*. Conceptualising the development of Reticulum into these areas serves to advance the implementation and work towards the Foundational Goals & Values of Reticulum.

+
+New Destination Rate Limiting
+=============================
+
+On public interfaces, where anyone may connect and announce new destinations,
+it can be useful to control the rate at which announces for *new*  destinations are
+processed.
+
+If a large influx of announces for newly created or previously unknown destinations
+occur within a short amount of time, Reticulum will place these announces on hold,
+so that announce traffic for known and previously established destinations can
+continue to be processed without interruptions.
+
+After the burst subsides, and an additional waiting period has passed, the held
+announces will be released at a slow rate, until the hold queue is cleared. This
+also means, that should a node decide to connect to a public interface, announce
+a large amount of bogus destinations, and then disconnect, these destination will
+never make it into path tables and waste network bandwidth on retransmitted
+announces.
+
+**It's important to note** that the ingress control works at the level of *individual
+sub-interfaces*. As an example, this means that one client on a :ref:`TCP Server Interface<interfaces-tcps>`
+cannot disrupt processing of incoming announces for other connected clients on the same
+:ref:`TCP Server Interface<interfaces-tcps>`. All other clients on the same interface will still have new announces
+processed without interruption.
+
+By default, Reticulum will handle this automatically, and ingress announce
+control will be enabled on interface where it is sensible to do so. It should
+generally not be neccessary to modify the ingress control configuration,
+but all the parameters are exposed for configuration if needed.
+
+ * | The ``ingress_control`` option tells Reticulum whether or not
+     to enable announce ingress control on the interface. Defaults to
+     ``True``.
+
+ * | The ``ic_new_time`` option configures how long (in seconds) an
+     interface is considered newly spawned. Defaults to ``2*60*60`` seconds. This
+     option is useful on publicly accessible interfaces that spawn new
+     sub-interfaces when a new client connects. 
+
+ * | The ``ic_burst_freq_new`` option sets the maximum announce ingress
+     frequency for newly spawned interfaces. Defaults to ``3.5``
+     announces per second.
+
+ * | The ``ic_burst_freq`` option sets the maximum announce ingress
+     frequency for other interfaces. Defaults to ``12`` announces
+     per second.
+
+     *If an interface exceeds its burst frequency, incoming announces
+     for unknown destinations will be temporarily held in a queue, and
+     not processed until later.*
+
+ * | The ``ic_max_held_announces`` option sets the maximum amount of
+     unique announces that will be held in the queue. Any additional
+     unique announces will be dropped. Defaults to ``256`` announces.
+
+ * | The ``ic_burst_hold`` option sets how much time (in seconds) must
+     pass after the burst frequency drops below its threshold, for the
+     announce burst to be considered cleared. Defaults to ``60``
+     seconds.
+
+ * | The ``ic_burst_penalty`` option sets how much time (in seconds) must
+     pass after the burst is considered cleared, before held announces can
+     start being released from the queue. Defaults to ``5*60``
+     seconds.
+
+ * | The ``ic_held_release_interval`` option sets how much time (in seconds)
+     must pass between releasing each held announce from the queue. Defaults

+<p>On public interfaces, where anyone may connect and announce new destinations,
+it can be useful to control the rate at which announces for <em>new</em>  destinations are
+processed.</p>
+<p>If a large influx of announces for newly created or previously unknown destinations
+occur within a short amount of time, Reticulum will place these announces on hold,
+so that announce traffic for known and previously established destinations can
+continue to be processed without interruptions.</p>
+<p>After the burst subsides, and an additional waiting period has passed, the held
+announces will be released at a slow rate, until the hold queue is cleared. This
+also means, that should a node decide to connect to a public interface, announce
+a large amount of bogus destinations, and then disconnect, these destination will
+never make it into path tables and waste network bandwidth on retransmitted
+announces.</p>
+<p><strong>It’s important to note</strong> that the ingress control works at the level of <em>individual
+sub-interfaces</em>. As an example, this means that one client on a <a class="reference internal" href="#interfaces-tcps"><span class="std std-ref">TCP Server Interface</span></a>
+cannot disrupt processing of incoming announces for other connected clients on the same
+<a class="reference internal" href="#interfaces-tcps"><span class="std std-ref">TCP Server Interface</span></a>. All other clients on the same interface will still have new announces
+processed without interruption.</p>
+<p>By default, Reticulum will handle this automatically, and ingress announce
+control will be enabled on interface where it is sensible to do so. It should
+generally not be neccessary to modify the ingress control configuration,
+but all the parameters are exposed for configuration if needed.</p>

+
+New Destination Rate Limiting
+=============================
+
+On public interfaces, where anyone may connect and announce new destinations,
+it can be useful to control the rate at which announces for *new*  destinations are
+processed.
+
+If a large influx of announces for newly created or previously unknown destinations
+occur within a short amount of time, Reticulum will place these announces on hold,
+so that announce traffic for known and previously established destinations can
+continue to be processed without interruptions.
+
+After the burst subsides, and an additional waiting period has passed, the held
+announces will be released at a slow rate, until the hold queue is cleared. This
+also means, that should a node decide to connect to a public interface, announce
+a large amount of bogus destinations, and then disconnect, these destination will
+never make it into path tables and waste network bandwidth on retransmitted
+announces.
+
+**It's important to note** that the ingress control works at the level of *individual
+sub-interfaces*. As an example, this means that one client on a :ref:`TCP Server Interface<interfaces-tcps>`
+cannot disrupt processing of incoming announces for other connected clients on the same
+:ref:`TCP Server Interface<interfaces-tcps>`. All other clients on the same interface will still have new announces
+processed without interruption.
+
+By default, Reticulum will handle this automatically, and ingress announce
+control will be enabled on interface where it is sensible to do so. It should
+generally not be neccessary to modify the ingress control configuration,
+but all the parameters are exposed for configuration if needed.
+
+ * | The ``ingress_control`` option tells Reticulum whether or not
+     to enable announce ingress control on the interface. Defaults to
+     ``True``.
+
+ * | The ``ic_new_time`` option configures how long (in seconds) an
+     interface is considered newly spawned. Defaults to ``2*60*60`` seconds. This
+     option is useful on publicly accessible interfaces that spawn new
+     sub-interfaces when a new client connects. 
+
+ * | The ``ic_burst_freq_new`` option sets the maximum announce ingress
+     frequency for newly spawned interfaces. Defaults to ``3.5``
+     announces per second.
+
+ * | The ``ic_burst_freq`` option sets the maximum announce ingress
+     frequency for other interfaces. Defaults to ``12`` announces
+     per second.
+
+     *If an interface exceeds its burst frequency, incoming announces
+     for unknown destinations will be temporarily held in a queue, and
+     not processed until later.*
+
+ * | The ``ic_max_held_announces`` option sets the maximum amount of
+     unique announces that will be held in the queue. Any additional
+     unique announces will be dropped. Defaults to ``256`` announces.
+
+ * | The ``ic_burst_hold`` option sets how much time (in seconds) must
+     pass after the burst frequency drops below its threshold, for the
+     announce burst to be considered cleared. Defaults to ``60``
+     seconds.
+
+ * | The ``ic_burst_penalty`` option sets how much time (in seconds) must
+     pass after the burst is considered cleared, before held announces can
+     start being released from the queue. Defaults to ``5*60``
+     seconds.
+
+ * | The ``ic_held_release_interval`` option sets how much time (in seconds)
