+Changes in libuca 1.1
+=====================
+
+Plugin System
+-------------
+
+A new plugin manager is used to instantiate camera objects from a shared
+library. Instead of calling `uca_camera_new`, a plugin manager is created that
+looks in pre- and user-defined directories for DSOs that match
+`libuca[A-Za-z].so` and used to instantiate:
+
+ UcaPluginManager *manager;
+ UcaCamera *camera;
+
+ manager = uca_plugin_manager_new ();
+ camera = uca_plugin_manager_get_camera (manager, "foo", &error);
+
+The plugin manager adds a dependency on GModule (pkg-config package
+`gmodule-2.0`) that is part of GLib.
+
+Minor changes
+-------------
+
+- It is now possible to generate GObject introspection meta data to bind libuca
+ to all languages that support GObject introspection.
+- Added uca_camera_stop_readout() to cleanup after using
+ uca_camera_start_readout().
+
Changes in libuca 1.0 aka 0.6
=============================
@@ -14,7 +42,6 @@ instead of trying to initialize each camera first and having the user decide
what to use, the user must now determine the used camera at compile time or use

@@ -381,6 +419,31 @@ virtual methods. The simplest way is to take the `mock` camera and
rename all occurences. Note, that if you class is going to be called `FooBar`,
the upper case variant is `FOO_BAR` and the lower case variant is `foo_bar`.
+In order to fully implement a camera, you need to override at least the
+following virtual methods:
+
+* `start_recording`: Take suitable actions so that a subsequent call to
+ `grab` delivers an image or blocks until one is exposed.
+* `stop_recording`: Stop recording so that subsequent calls to `grab`
+ fail.
+* `grab`: Return an image from the camera or block until one is ready.
+
+## Asynchronous operation
+
+When the camera supports asynchronous acquisition and announces it with a true
+boolean value for `"transfer-asynchronously"`, a mechanism must be setup up
+during `start_recording` so that for each new frame the grab func callback is
+called.
+
+## Cameras with internal memory
+
+Cameras such as the pco.dimax record into their own on-board memory rather than
+streaming directly to the host PC. In this case, both `start_recording` and
+`stop_recording` initiate and end acquisition to the on-board memory. To
+initiate a data transfer, the host calls `start_readout` which must be suitably
+implemented. The actual data transfer happens either with `grab` or
+asynchronously.

+ * as one of #UcaPluginManagerError codes. To get a list of available camera
+ * names call uca_plugin_manager_get_available_cameras().
+ *
+ * By default, any path listed in the %UCA_CAMERA_PATH environment variable is
+ * added to the search path.
