This file lists notable changes in each release. For the full history of all
changes, see ChangeLog.

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
  - Remove sleep() in enroll example which caused a crash in some drivers
  - Add a simple storage implementation example

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:
  - Add USB ID for TNP Nano USB Fingerprint Reader
  - Fix UPEKTS enrollment never finishing on some devices

* Library:
  - Fix fp_get_pollfds() retval type, a small ABI change
  - Downgrade fatal errors to run-time warnings, as a number of drivers
    used to throw silent errors and we made them fatal. Those will now
    be visible warnings, hopefully helping with fixing them.

2018-06-12: v0.8.1 release
- Brown paperbag release to install the udev rules file in the correct
  directory if the udev pkg-config file doesn't have a trailing slash

  - Add Elan driver
  - Increase threshold to detect encryption on URU4000 devices
  - Remove already replaced UPEKE2 driver
  - Fix possible crash caused by vfs5011 when no lines were captured

* Library:
  - Fix a number of memory and file descriptor leaks and warnings
  - Make NSS (and URU4000) driver optional
  - Fix assembling of frames for non-reverse and non reverse stripes
  - Split internal private header to clarify drivers API
  - Simplify logging system, now all the builds can be used to output
    debug information
  - Mark fp_dscv_print functions as deprecated

* Udev rules:
  - Add some unsupported devices to the whitelist

* Library:
  - NBIS: Remove false minutia at the edge of partial image
  - Introduce routines to assemble image from lines (used in VFS5011 and upeksonly)
  - Fix a bug that can cause driver state machine to enter into endless loop. 

* Udev rules:
  - Add driver name to the USB properties

* Plenty of build fixes
