+## [2.4.9] - 2023-08-13
+
+### Added
+
+-   Error tests added in tests/test_errors.py
+-   Errors section in README updated.
+
+### Changed
+
+-   VBANCMDConnectionError class now subclasses VBANCMDError
+-   If the configs loader is passed an invalid config TOML it will log an error but continue to load further configs into memory.
+
+## [2.3.2] - 2023-07-12
+
+### Added
+
+-   vban.{instream,outstream} tuples now contain classes that represent MIDI and TEXT streams.
+
+### Fixed
+
+-   apply_config() now performs a deep merge when extending a config with another.
+
+## [2.3.0] - 2023-07-11
+
+### Added
+
+-   user configs may now extend other user configs. check `config extends` section in README.
+
+## [2.2.0] - 2023-07-08
+
+### Added
+
+-   button, vban classes implemented
+-   \__repr\__() method added to base class
+
+## [2.1.2] - 2023-07-05
+
+### Added
+
+-   `outbound` kwarg let's you disable incoming rt packets. Essentially the interface will work only in one direction.
+
+This is useful if you are only interested in sending commands out to voicemeeter but don't need to receive parameter states.
+
+By default outbound is False.
+
+-   sendtext logging added in base class.
+
+### Fixed
+
+-   Bug in apply() if invoked from a higher class (not base class)
+
+## [2.0.0] - 2023-06-25
+
+This update introduces some breaking changes:
+
+### Changed
+
+-   `strip[i].comp` now references StripComp class
+    -   To change the comp knob you should now use the property `strip[i].comp.knob`
+-   `strip[i].gate` now references StripGate class
+
+    -   To change the gate knob you should now use the property `strip[i].gate.knob`
+
+-   `bus[i].eq` now references BusEQ class
+
+    -   To set bus[i].{eq,eq_ab} as before you should now use bus[i].eq.on and bus[i].eq.ab
+
+-   new error class `VBANCMDConnectionError` raised when a connection fails or times out.
+
+There are other non-breaking changes:
+
+### Changed
+
+-   now using a producer thread to send events to the updater thread.
+-   factory.request_vbancmd_obj simply raises a `VBANCMDError` if passed an incorrect kind.
+-   module level loggers implemented (with class loggers as child loggers)
+
+### Added
+
+-   `strip[i].eq` added to PhysicalStrip
+
+## [1.8.0]
+
+### Added
+
+-   Connection section to README.
+
+### Changed
+
+-   now using clear_dirty() when sync enabled.
+
+### Fixed
+
+-   bug in set_rt() where multiple commands sent in single request packet.
+-   bug in apply where index was sent twice.
+
+## [1.7.0]
+
+### Added
+
+-   ability to read conn info from vban.toml config
+
+### Changed
+
+-   assume a vban.toml in examples. README's modified.
+
+## [1.6.0] - 2022-10-06
+
+### Added
+
+-   fadeto(), fadeby() methods added to strip/bus classes.
+-   OBS example added.
+
+### Changed
+
+-   Event class add/remove now accept iterables.
+-   property setters added to Event class.
+-   ldirty logic moved into VbanRtPacket class.
+-   in util, threshold a level is considered dirty moved to 7200 (-72.0)
+-   now print bus levels in observer example.
+
+### Fixed
+
+-   initialize comps in updater thread. fixes bug when switching to a kind before any level updates
+
+## [1.5.0] - 2022-09-28
+
+### Changed
+
+-   Logging module used in place of print statements across the interface.
+-   base error name changed (VBANCMDError)
+
+### Fixed

+-   Timeout and raise connection error when socket connection fails.
+-   Bug in observer example

+    "ip": "<ip address>",

+-   `pdirty`: boolean
+-   `ldirty`: boolean
+
+example:
+
+```python
+vban.event.ldirty = True
+
+vban.event.pdirty = False
+```
+
+Or add, remove a list of events.

 -   `ip`: str, ip or hostname of remote machine
 -   `streamname`: str, name of the stream to connect to.
 -   `port`: int=6980, vban udp port of remote machine.
--   `subs`: dict={"pdirty": True, "ldirty": False}, controls which updates to listen for.
+-   `pdirty`: boolean=False, parameter updates
-    -   `pdirty`: parameter updates
+-   `ldirty`: boolean=False, level updates
-    -   `ldirty`: level updates
+-   `timeout`: int=5, amount of time (seconds) to wait for an incoming RT data packet (parameter states).
-
+-   `outbound`: boolean=False, set `True` if you are only interested in sending commands. (no rt packets will be received)
-#### Event updates
-
-To receive event updates you should do the following:
-
--   register your app to receive updates using the `vban.subject.add(observer)` method, where observer is your app.
--   define an `on_update(subject)` callback function in your app. The value of subject may be checked for the type of update.

-
-Level updates are considered high volume, by default they are NOT listened for.

+## About
+
+A single channel GUI demonstrating controls for the first virtual strip if Voicemeeter Banana.
+
+This example demonstrates (to an extent) two way communication. 
+-   Sending parameters values to the Voicemeeter driver.
+-   Receiving level updates
+
+Parameter updates (pdirty) events are not being received so changing a UI element on the main Voicemeeter app will not be reflected in the example GUI.
+
+## Use
+
+Simply run the script and try the controls.

+## Requirements
+
+-   [OBS Studio](https://obsproject.com/)
+-   [OBS Python SDK for Websocket v5](https://github.com/aatikturk/obsws-python)
+
+## About
+
+Perhaps you have a streaming setup but you want to control OBS and Voicemeeter from a remote location with python installed.
+With the vban-cmd and obsws-python packages you may sync a distant Voicemeeter with a distant OBS over LAN.
+
+## Configure
+
+This script assumes the following:
+
+-   OBS Connection info in a valid `config.toml`:
+
+    ```toml
+    [connection]
+    host = "gamepc.local"
+    port = 4455
+    password = "mystrongpass"
+    ```
+
+-   VBAN Connection info in a valid `vban.toml`:
+
+    ```toml
+    [connection]
+    ip = "gamepc.local"
+    port = 6980
+    streamname = "Command1"
+    ```
+
+-   Both configs should be placed next to `__main__.py`.
+
+-   Four OBS scenes named "START", "BRB", "END" and "LIVE".
+
+## Use
+
+Make sure you have established a working connection to OBS and the remote Voicemeeter.
+
+Run the script, change OBS scenes and watch Voicemeeter parameters change.
+
+Closing OBS will end the script.
+
+## Notes
+
+All but `vban_cmd.iremote` logs are filtered out. Log in DEBUG mode.
+
+This script can be run from a Linux host since the vban-cmd interface relies on UDP packets and obsws-python runs over websockets.
+
+You could for example, set this up to run in the background on a home server such as a Raspberry Pi.
+
+It requires Python 3.10+.
