|
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
|
|
sunken reference rather than a floating one. Most API users will have
|
|
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.
|
|
|
|
Highlights:
|
|
* Object reference management fixes for FpPrint and identify
|
|
* Fixed issues that caused problem on non-x86 machines (#236)
|
|
* Fix building with older GLib versions
|
|
* synaptics: Support PID 00e7
|
|
* 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)
|

|
|
* vfs301: Fix driver and add CI test (#320)
|
|
|
|
2020-06-08: v1.90.3 release
|
|
|
|
This release mostly contains support for a number of new match-on-chip
|
|
devices. Most notable is the addition of the new goodixmoc driver.
|
|
Currently the driver has the small caveat that we have no strategy to
|
|
garbage collect old prints yet (a simple strategy could be implemented
|
|
in fprintd).
|
|
|
|
Highlights:
|
|
* New goodixmoc driver supporting Goodix USB devices:
|
|
27C6:5840
|
|
27C6:6496
|
|
27C6:60A2
|
|
* Newly added support for Synaptics device:
|
|
06CB:00E9
|
|
06CB:00DF
|
|
* Fixed an issue with Synaptics devices sometimes not working at boot
|
|
* Fix issue with aes3k driver (#306)
|
|
|
|
2020-06-08: v1.90.2 release
|
|
|
|
This release contains a large amount of bug and regression fixes. These
|
|
are not listed explicitly, but affect the majority of drivers.
|
|
|
|
Highlights:
|
|
* A patch for nbis required for some sensors was accidentally dropped in
|
|
an earlier release. Users of these sensors/drivers (aes1610, aes2501,
|
|
aes2550, aes1660, aes2660, elan, upektc_img) need to re-enroll (#142).
|
|
|
|
2019-11-20: v1.90.1 release
|
|
|
|
This release fixes a lot of the regressions introduced in 1.90.0. Please note
|
|
that both the driver and external APIs have changed, as both the verify and
|
|
the identify functions now have early reporting mechanisms.
|
|
The soname for the library, as well as a number of file locations have also
|
|
changed. While this allows installation in parallel with the 1.0 version of
|
|
libfprint, we recommend installing only one, and migrating from version 1.0 to
|
|
version 2.0 alongside its main consumer (fprintd).
|
|
|
|
Only major changes are listed below. A lot of other cleanup work and small
|
|
fixes have also been merged.
|
|
|
|
* Library:
|
|
- Add support to run tests in gdb/valgrind
|
|
- Allow testing on all architectures
|
|
- Avoid image device AWAIT_FINGER_ON to deactivate state transitions
|
|
- Fix verify/identify error propagation to library user
|
|
- Correctly read image device information from class data
|
|
- Continue enroll after an image driver reported a retry error
|
|
- Change external API to allow reporting match results early
|
|
- A lot of new unit tests and integration tests have been added
|
|
|
|
* Drivers API
|
|
- 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:
|
|
- elan: Ensure correct deactivation of device
|
|
- uru4000: Fix IRQ handler registration and internal state handling
|
|
- uru4000: Fix control transfer request type
|
|
- synaptics: Ensure errors are only reported after finger removal
|
|
|
|
2019-11-20: v1.90.0 release
|
|
|
|
This release updates the core of the library to use GLib routines and Gio
|
|
style APIs. While the API both for library users remain similar in most
|
|
ways, there are some changes and all users will need to be ported.
|
|
|
|
A large motivation for the in-depth changes was the requirement to add
|
|
new API to support sensors that store the prints on the sensor. This
|
|
support is already used by the new synaptics driver, which will support
|
|
the current generation of the Prometheus MIS (match-in-sensor) chipset
|
|
by Synaptics (USB ID 06cb:00bd).
|
|
|
|
The current codebase is considered stable at this point. However, due to
|
|
the lack of wider testing it is only released as a 1.90.0 release which
|
|
can be considered a beta-release for 2.0.
|
|
|
|
With the rewrite, it is now also possible to support devices that are not
|
|
connected through USB (e.g. I2C). Another major improvement is that the
|
|
library has now a test suite, testing both the library core and allowing
|
|
tests of the drivers using umockdev.
|
|
|
|
2019-08-08: v1.0 release
|
|
* Library:
|
|
- Add guards to the public API and require GLib 2.50
|
|
- Deprecate print storage API
|
|
- Better documentation for fp_discover_devs()
|
|
- Remove unused internal fpi_timeout_cancel_for_dev()
|
|
- Remove state from fp_img_driver activate handler
|
|
- Bug fixes related to restarting a failed verification immediately
|
|
|
|
* Drivers:
|
|
- The Elan driver received a lot of bug fixes including a fix for a
|
|
hang when verifying prints with fprintd, quirks for some devices,
|
|
a memory leak fix and support for 04f3:0c42
|
|
- Fix a probable crash in all the AES drivers
|
|
- Add support for Lenovo Preferred Pro Keyboard (KUF1256) to vfs5011
|
|
- Prevent hang during enroll process in etes603 driver
|
|
- Fix possible integer overflow in uru4000
|
|
- Work-around SELinux AVC warnings when uru4000 driver starts
|
|
- Remove long-unmaintained and broken fdu2000 driver
|
|
|
|
* Tools/Examples:
|
|
- Fix examples not working due to an overly strict check
|
|
- Fix crash in GTK demo when there's no supported devices
|
|
- Disable GTK demo until we have a USB Flatpak portal
|
|

|
|

|
|
|
|
2018-12-14: v0.99.0 release
|
|
* Library:
|
|
- All the internal API for device driver writers is now covered by the
|
|
documentation and has been enhanced to make it easier to write drivers
|
|
- Update internal NBIS fingerprint data processing library to one that's
|
|
nearly 10 years newer
|
|
- Re-add accessor for minutia coordinates which was used in the very
|
|
old fprint_demo program, but also by our new GTK+ test program (see below)
|
|
- Fix a crash when too many minutiae were detected in a capture
|
|
|
|
* Drivers:
|
|
- Support more devices in the Elan driver, stability improvements
|
|
|
|
* Tools:
|
|
- Add a test GTK+ application that will eventually be used for testing
|
|
drivers without modifying the OS installed version. Note that this
|
|
application currently requires manually changing permissions of USB
|
|
devices, this will be fixed when the infrastructure exists to access
|
|
those devices without additional permissions, as a normal user.
|
|
|
|
2018-07-15: v0.8.2 release
|
|
* Drivers:

|
|
be visible warnings, hopefully helping with fixing them.
