 -   [x]
 
+## [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
