[sane-announce] SANE Backends 1.0.31 released

[Olaf Meeuwissen]

Hi all,

Six months and three weeks after sane-backends-1.0.29 and about three
months after our sane-backends-1.0.30 security update, I'm happy to
announce that sane-backends-1.0.31 has been released.  You can find
the latest source tarballs and checksums on the [releases page][1] in
the Other section of the Assets.

 [1]: https://gitlab.com/sane-project/backends/-/releases

The page also mentions several "Source code" links in the Assets from
which you can download the git repository corresponding to the release.
Please note that these archives do *not* include generated files such as
the configure script, Makefile.in files and more.

A nicely formatted version of the release notes can be found at the same
location but, for your convenience, the "raw" Markdown has been included
below.

### Backends

- adds the `canon_lide70` backend
- `avision`: adds support for the KODAK i1120, fixes thread
  cancellation issues, disables exposure option for non-filmscanners
- `canon_dr`: improves error reporting
- `dmc`: fixes compiler warnings on the scan area options
- `epsonds`: rewrites the network I/O following changes made to the
  `epson2` backend in 1.0.30 to fix security issues.  Network support
  is still unsupported.
- `escl`: adds ADF support, fixes many minor issues and improves error
  handling.  Now also supports devices behind a proxy (needs explicit
  configuration).
- `fujitsu`: adds support for the fi-800R and a card scanning slot,
  fixes a bug when reading hardware sensors on the first invocation.
  Adds USB IDs for fi-7800 and fi-7900.
- `genesys`: adds support for the Canon 5600F, Canon LiDE 90, Plustek
  OpticFilm 7200 and 7200 (v2), 7400, 7600i, 8100 and 8200i.  Fixes
  several issues with the Canon 8600F.  Adds 4800dpi support for the
  Canon LiDE 210 and fixes 3200dpi flatbed support on the Canon 8400F.
  Adds an option to fill dark calibration with a constant.  Adds
  transparency support for gl847 chipset based devices.  Fixes CIS
  scanner support for gl842 chipset based devices.  Removes lineart
  and image enhancement emulation support.
- `gphoto`: supports the PLANon DocuPen RC800 (with a recent enough
  version of `gphoto2`)
- `gt68xx`: modifies scan cancellation behaviour
- `hp5400`: adds button support, fixes a scan cancellation crash issue
- `pixma`: add supports for the i-SENSYS MF440 Series and untested
  support for the PIXMMA G7000 Series and GM4000 Series as well as the
  i-SENSYS MF720 Series.
- `plustek`: fixes a potential buffer overrun
- `test`: adds gamma options

### Documentation

- removes the SANE Standard.  This is now maintained as a separate
  project at https://gitlab.com/sane-project/standard.  HTML and PDF
  versions can be found at https://sane-project.gitlab.io/standard/.
- adds and updates information for multiple supported and unsupported
  devices
- translation updates for British English, French, German, Italian and
  Ukranian
- `scanimage`: documents the JPEG compression level
- minor improvements documenting build requirements

### Build

- removes the `--with-api-spec` option from `configure`
- replaces the `--enable-avahi` option with an `--with-avahi` that
  defaults to enabling if possible.  If the option is given and the
  required support is not available, `configure` will exit with an
  error.
- improves checking for libjpeg version dependent requirements
- has been made reproducable (#228)
- fixes build issues on MinGW

### Miscellaneous

- fixes OpenBSD hotplugd scriptlets (!375)
- fixes support for unconfigured USB scanners on MacOS (#38)
- various fixes and improvements in the USB record/replay support
- fixes a file descriptor validation test in sanei_pio
