 -   [x]
 
+## [2.9.0] - 2026-03-02
+
+### Added
+
+-   Recorder class, see [Recorder](https://github.com/onyx-and-iris/vban-cmd-python?tab=readme-ov-file#recorder) in README.
+-   Ping/pong implemented. If a pong is not received {VbanCmd}.login() will fail fast. This prevents the rt listener threads from starting up.
+    -   It has the added benefit of automatically detecting the type of VBAN server (Voicemeeter or Matrix).
+-   A thread lock around the framecounter to improve thread safety since it can be accessed by both the main thread and the Producer thread.
+
+
+## [2.7.0] - 2026-03-01
+
+### Added
+
+-   new kind `matrix` has been added, it does two things:
+    -   scales the interface according to `potato` kind, in practice this has no affect but it's required by the builder classes.
+    -   disables the rt listener threads since we aren't expecting to receive any from a Matrix VBAN server.
+        -   however, matrix responses may still be received with the {VbanCmd}.sendtext() method.
+
+### Changed
+
+-   `outbound` kwarg has been renamed to `disable_rt_listeners`. Since it's job is to disable the listener threads for incoming RT packets this new name is more descriptive.
+-   dataclasses representing packet headers and packets with ident:0 and ident:1 have been moved into an internal packet module.
+
+### Removed
+
+-   {VbanCmd}.sendtext() @script decorator removed. It's purpose was to attempt to convert a dictionary to a script but it was poorly implemented and there exists the {VbanCmd}.apply() method already.
+
+## [2.6.0] - 2026-02-26
+
+### Added
+
+-   support for packet with [ident:1](https://github.com/onyx-and-iris/Voicemeeter-SDK/blob/3be2c1c36563afbd6df3da8436406c77d2cc1f10/VoicemeeterRemote.h#L982) in VBAN TEXT subprotocol.
+    -   This includes Strip 3D, PEQ, comp, gate, denoiser and pitch parameters.
+
+## [2.5.2] - 2025-01-25
+
+### Changed
+
+-   ip kwargs defaults to 'localhost'
+-   bps kwarg defaults to 256000.
+-   factory builder steps now logged at `DEBUG` level.
+-   Internal socket changes, they don't affect interface usage.
+
+## [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
+
+## [1.4.0] - 2022-09-03

 ## Requirements
 
 -   [Voicemeeter](https://voicemeeter.com/)
--   Python 3.11 or greater
+-   Python 3.10 or greater
 
 ## Installation
 
-### `Pip`
-
-Install vban-cmd package from your console
-
-`pip install vban-cmd`
+```console
+pip install vban-cmd
+```
 
 ## `Use`
 
+#### Connection
+
+Load VBAN connection info from toml config. A valid `vban.toml` might look like this:
+
+```toml
+[connection]
+host = "localhost"
+port = 6980
+streamname = "Command1"
+```
+
+It should be placed in \<user home directory\> / "Documents" / "Voicemeeter" / "configs"
+
+Alternatively you may pass `host`, `port`, `streamname` as keyword arguments.
+
+#### `__main__.py`
+
 Simplest use case, use a context manager to request a VbanCmd class of a kind.
 
 Login and logout are handled for you in this scenario.

+## 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+.

+## About
+
+Registers a class as an observer and defines a callback.
+
+## Configure
+
+The script assumes you have connection info saved in a config file named `vban.toml` placed next to `__main__.py`.
+
+A valid `vban.toml` might look like this:
+
+```toml
+[connection]
+ip = "gamepc.local"
+port = 6980
+streamname = "Command1"
+```
+
+It should be placed next to `__main__.py`.
+
+## Use
+
+Make sure you have established a working VBAN connection.
+
+Run the script, then:
+
+-   change GUI parameters to trigger pdirty
+-   play audio through any bus to trigger ldirty
+
+Pressing `<Enter>` will exit.
