+
+2020-12-01: v1.90.6 release
+
+This release is primarily a bugfix release for some older issues.
+
+The major change is that fp_print_deserialize will now correctly return a

+assumed this was true, and issues could happen at a later point.
+If any API user worked around this libfprint bug, they will now leak the
+returned print.

+ * goodix: Fix issue with long USB packages
+
+
+2020-12-01: v1.90.5 release
+
+The 1.90.4 release caused a major regression, as it included a USB hub in
+UDEV the autosupend rule list.
+
+Highlights:
+ * Remove USB hub from udev autosupend rules
+ * synaptics: Add PID 0x00c9 which is used in some HP laptops
+
+
+2020-11-27: v1.90.4 release
+
+This release contains a number of important bugfixes. On the feature side,
+the USB hotplug support was improved. A lot of drivers received fixes and
+improvements.
+
+Highlights:
+ * Work around GUsb cancellation issue
+ * Redefine internal image device state machine for more robustness
+ * Add public finger-status reporting to FpDevice
+ * Rework device removal API to be convenient (#330)
+ * Enable powersave for unsupported USB devices
+ * Improvements to examples
+ * synaptics: Support identify operation
+ * synaptics: Fix possible crash when the interrupt transfer is resubmitted
+ * synaptics: Add support for PIDs 0x00f9, 0x00fc and 0x00c2
+ * elan: Add PID 0x0c4d to supported device list
+ * aes3k: Fix driver and add CI test (#306)
+ * uru4000: Fix reference counting of image transfer
+ * vfs301: Fix driver and add CI test (#320)

+### libfprint-TOD v1
+
+- First public release
+- Based on [libfprint 1.90.1](https://gitlab.freedesktop.org/libfprint/libfprint/-/releases#v1.90.1)
+- Bumped TOD version to 1
+
+### Highlights of the Drivers API changes
+
+Both the driver and external APIs have changed, as both the verify and the identify functions now have early reporting mechanisms.
+
+- Added API for early report of matching results or retry errors
+- Verify and identification completion functions have been simplified
+- Support variadic arguments in error functions
+- Various re-definitions of ownership handling
+- Add convenience API to change state after a timeout
+- Add unit tests for all the drivers API
+
+### Drivers required changes
+As per the early report mechanism, drivers need to adapt, in particular:
+ - New pkg-config dependency name is `libfprint-2-tod-1`
+ - Verification and Identification API for non-image drivers has changed and drivers need to both `report` the result of the action and complete it:
+   - `fpi_device_{verify,identify}_report` must inform whether a match/no-match or identification happened or report a *retry error*.
+   - `fpi_device_{verify,identify}_complete` must be called once the device has completed the verification / identification process,  in case reporting device errors (not retry ones!)
+
+You can see examples of changes needed in the [reference example driver](https://gitlab.freedesktop.org/3v1n0/libfprint-tod-example-driver/-/commit/8308f84f7d1cfd1b9ed0936c13c73b43a4a46772) or the [upstream synaptics driver](https://gitlab.freedesktop.org/libfprint/libfprint/-/merge_requests/112/diffs)

-libfprint
-=========
-
-libfprint is part of the fprint project:
-https://fprint.freedesktop.org/
-
-libfprint was originally developed as part of an academic project at the
-University of Manchester with the aim of hiding differences between different
-consumer fingerprint scanners and providing a single uniform API to application
-developers. The ultimate goal of the fprint project is to make fingerprint
-scanners widely and easily usable under common Linux environments.
-
-The academic university project runs off a codebase maintained separately
-from this one, although I try to keep them as similar as possible (I'm not
-hiding anything in the academic branch, it's just the open source release
-contains some commits excluded from the academic project).
-
-THE UNIVERSITY OF MANCHESTER DOES NOT ENDORSE THIS THIS SOFTWARE RELEASE AND
-IS IN NO WAY RESPONSIBLE FOR THE CODE CONTAINED WITHIN, OR ANY DAMAGES CAUSED
-BY USING OR DISTRIBUTING THE SOFTWARE. Development does not happen on
-university computers and the project is not hosted at the university either.

-libfprint is licensed under the GNU LGPL version 2.1. See the COPYING file
-for the license text.
-
-Section 6 of the license states that for compiled works that use this
-library, such works must include libfprint copyright notices alongside the
-copyright notices for the other parts of the work. We have attempted to
-make this process slightly easier for you by grouping these all in one place:
-the AUTHORS file.
-
-libfprint includes code from NIST's NBIS software distribution:
-http://fingerprint.nist.gov/NBIS/index.html
-We include bozorth3 from the US export controlled distribution. We have
-determined that it is fine to ship bozorth3 in an open source project,
-see https://fprint.freedesktop.org/us-export-control.html

+
+## History
+
+**LibFPrint** was originally developed as part of an
+academic project at the **[University Of Manchester]**.
+
+It aimed to hide the differences between consumer
+fingerprint scanners and provide a single uniform
+API to application developers.
+
+## Goal
+
+The ultimate goal of the **FPrint** project is to make
+fingerprint scanners widely and easily usable under
+common Linux environments.
+
+## License
+
+`Section 6` of the license states that for compiled works that use
+this library, such works must include **LibFPrint** copyright notices
+alongside the copyright notices for the other parts of the work.
+
+**LibFPrint** includes code from **NIST's** **[NBIS]** software distribution.
+
+We include **Bozorth3** from the **[US Export Controlled]**
+distribution, which we have determined to be fine
+being shipped in an open source project.

+### libfprint-TOD - libfprint for Touch OEM Drivers
+
+This is a light fork of libfprint to expose internal Drivers API in order to
+create drivers as shared libraries.
+
+Fork is hosted at: https://gitlab.freedesktop.org/3v1n0/libfprint/tree/tod
+
+An example driver implementation is available:

+### libfprint-TOD - libfprint for Touch OEM Drivers
+
+This is a light fork of libfprint to expose internal Drivers API in order to
+create drivers as shared libraries.
+
+Fork is hosted at: https://gitlab.freedesktop.org/3v1n0/libfprint/tree/tod
+
+Packaging for this is handled via gbp, so you need to make sure that you have
+added the remote:
+
+    git remote add origin-tod https://gitlab.freedesktop.org/3v1n0/libfprint.git
+    git fetch origin-tod --tags
+
+To get the latest tod release, just use `gbp import-orig --uscan`.

+Description: async fingerprint library of fprint project, shared libraries
+ The fprint project aims to support for consumer fingerprint reader devices.
+ .
+ Previously, Linux support for such devices has been scattered amongst different
+ projects (many incomplete) and inconsistent in that application developers
+ would have to implement support for each type of fingerprint reader separately.
+ The idea is to change that by providing a central system to support all the

+ .
+ libfprint is the centre of efforts, this component does the dirty job of
+ talking to fingerprint reading devices, and processing fingerprint data.
+ .
+ This library depends on the new libusb, which performs asynchronous callbacks,
+ allowing fprint to perform non-blocking device tasks.
