+## [2.0.0] - 2023-06-25
+
+Where possible I've attempted to make the changes backwards compatible. The breaking changes affect two higher classes, Strip and Bus, as well as the behaviour of events. All other changes are additive or QOL aimed at giving more options to the developer. For example, every low-level CAPI call is now logged and error raised on Exception, you can now register callback functions as well as observer classes, extra examples to demonstrate different use cases etc.
+
+The breaking changes are as follows:
+
+### 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
+
+-   by default, <strong>NO</strong> events are checked for. This is reflected in factory.FactoryBase defaultkwargs.
+    -   This is a fundamental behaviour change from version 1.0 of the wrapper. It means the following:
+        -   Unless any events are explicitly requested with an event kwarg the event emitter thread will not run automatically.
+        -   Whether using a context manager or not, you can still initiate the event thread manually and request events with the event object.<br>
+            see `events` example.
+
+There are other non-breaking changes:
+
+### Added
+
+-   `strip[i].eq` added to PhysicalStrip
+-   `strip[i].denoiser` added to PhysicalStrip
+-   `Strip.Comp`, `Strip.Gate`, `Strip.Denoiser` sections added to README.
+-   `Events` section in readme updated to reflect changes to events kwargs.
+-   new comp, gate, denoiser and eq tests added to higher tests.
+-   `levels` example to demonstrate use of the interface without a context manager.
+-   `events` example to demonstrate how to interact with event thread/event object.
+-   `gui` example to demonstrate GUI controls.
+-   `{Remote}.observer` can be used in place of `{Remote}.subject` although subject will still work. Check examples.
+-   Subject class extended to allow registering/de-registering callback functions (as well as observer classes). See `events` example.
+
+### Changed
+
+-   `comp.knob`, `gate.knob`, `denoiser.knob`, `eq.on` added to phys_strip_params in config.TOMLStrBuilder
+
+    -   The `example.toml` config files have been updated to demonstrate setting new comp, gate and eq settings.
+
+-   event kwargs can now be set directly. no need for `subs`. example: `voicemeeterlib.api('banana', midi=True})`
+
+-   factorybuilder steps now logged in DEBUG mode.
+
+-   now using a producer thread to send events to the updater thread.
+
+-   module level loggers implemented (with class loggers as child loggers)
+
+-   config.loader now checks `Path.home() / ".config" / "voicemeeter" / kind.name` for configs.
+    -   note. `Path(__file__).parent / "configs" / kind.name,` was removed as a path to check.
+
+### Fixed
+
+-   All low level CAPI calls are now wrapped by CBindings.call() which logs any errors raised.
+-   Dynamic binding of Macrobutton functions from the CAPI.
+    Should add backwards compatibility with very old versions of the api. See [Issue #4][issue 4].
+-   factory.request_remote_obj now raises a `VMError` if passed an incorrect kind.
+
+## [1.0.0] - 2023-06-19
+
+No changes to the codebase but it has been stable for several months and should already have been bumped to major version 1.0
+
+I will move this commit to a separate branch in preparation for version 2.0.

+### Added
+
+-   StripDevice and BusDevice mixins.
+-   README updated to reflect changes.
+-   Minor version bump

+
+### Changed
+
+-   Event class property setters added.
+-   Event add/remove methods now accept multiple events.
+-   bus levels now printed in observer example.
+
+### Fixed
+
+-   initialize channel comps in updater thread. Fixes bug when switching to a kind before any level updates have occurred.
+
+## [0.8.0] - 2022-09-29
+
+### Added
+
+-   Logging level INFO set on all examples.
+-   Minor version bump

-`voicemeeterlib.api(kind_id: str)`
-
-You may pass the following optional keyword arguments:
-
--   `sync`: boolean=False, force the getters to wait for dirty parameters to clear. For most cases leave this as False.
--   `ratelimit`: float=0.033, how often to check for updates in ms.
--   `subs`: dict={"pdirty": True, "mdirty": True, "midi": True, "ldirty": False}, initialize which event updates to listen for.
-    -   `pdirty`: parameter updates
-    -   `mdirty`: macrobutton updates
-    -   `midi`: midi updates
-    -   `ldirty`: level updates
-
-#### Event updates
-
-To receive event updates you should do the following:
-
--   register your app to receive updates using the `vm.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 event.
-
-See `examples/observer` for a demonstration.
-
-Level updates are considered high volume, by default they are NOT listened for. However, polling them with strip.levels and bus.levels methods will still work.
-
-So if you don't wish to receive level updates, or you prefer to handle them yourself simply leave ldirty as default (False).
-
-Each of the update types may be enabled/disabled separately. Don't use a midi controller? You have the option to disable midi updates.
+By default, NO events are listened for. Use events kwargs to enable specific event types.
 
 example:
 
 ```python
 import voicemeeterlib
-# Set updates to occur every 50ms
-# Listen for level updates but disable midi updates
-with voicemeeterlib.api('banana', ratelimit=0.05, subs={"ldirty": True, "midi": False}) as vm:
+# Set event updates to occur every 50ms
+# Listen for level updates only
+with voicemeeterlib.api('banana', ratelimit=0.05, ldirty=True}) as vm:
+    ...
+```
+
+#### `vm.observer`
+
+Use the Subject class to register an app as event observer.
+
+The following methods are available:
+
+-   `add`: registers an app as an event observer
+-   `remove`: deregisters an app as an event observer
+
+example:
+
+```python
+# register an app to receive updates
+class App():
+    def __init__(self, vm):
+        vm.observer.add(self)
         ...
 ```
 
 #### `vm.event`
 
-You may also add/remove event subscriptions as necessary with the Event class.
+Use the event class to toggle updates as necessary.
+
+The following properties are available:
+
+-   `pdirty`: boolean
+-   `mdirty`: boolean
+-   `midi`: boolean
+-   `ldirty`: boolean
 
 example:
 
 ```python
-vm.event.add("ldirty")
+vm.event.ldirty = True
 
-vm.event.remove("pdirty")
+vm.event.pdirty = False
+```
+
+Or add, remove a list of events.
+
+The following methods are available:
+
+-   `add()`
+-   `remove()`
+-   `get()`
+
+example:
+
+```python
+vm.event.remove(["pdirty", "mdirty", "midi"])

+## About
+
+This script demonstrates how to interact with the event thread/event object. It also demonstrates how to register event specific callbacks.
+
+By default the interface does not broadcast any events. So even though our callbacks are registered, and the event thread has been initiated, we won't receive updates.
+
+After five seconds the event object is used to subscribe to all events for a total of thirty seconds.
+
+Remember that events can also be unsubscribed to with `vm.event.remove()`. Callbacks can also be deregistered using vm.observer.remove().
+
+The same can be done without a context manager:
+
+```python
+    vm = voicemeeterlib.api(KIND_ID)
+    vm.login()
+    vm.observer.add(on_midi)    # register an `on_midi` callback function
+    vm.init_thread()
+    vm.event.add("midi")    # in this case we only subscribe to midi events.
+    ...
+    vm.end_thread()
+    vm.logout()
+```
+
+Once initialized, the event thread will continously run until end_thread() is called. Even if all events are unsubscribed to.
+
+## Use
+
+Simply run the script and trigger events and you should see the output after 5 seconds. To trigger events do the following:
+
+-   change GUI parameters to trigger pdirty
+-   press any macrobutton to trigger mdirty
+-   play audio through any bus to trigger ldirty
+-   any midi input to trigger midi

+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.
