-
-2020-12-01: v1.90.7 release
-
-Highlights:
- * vfs5011: Fix possible use-after-free
- * goodixmoc: Add two new PIDs (0x63AC, 0x639C)
- * goodixmoc: Support finger status API
- * synaptics: Only identify within provided prints
- * synaptics: Reject devices with old firmware during probe (#239)
-
-
-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)
- * 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)
-
-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
