SANE

## New with 1.0.28 (released 2019-07-31) ### Backends - adds a `ricoh2` backend - adds support for 40+ new scanner models - significantly changes `canon_dr`, `fujitsu`, `genesys`, `gt68xx`, `hp5590` and, `pixma` backends - fixes bugs in `as6e`, `avision`, `mustek` and `plustek` backends - fixes scores of compiler warnings ### Frontends - adds, changes and removes options for `saned` (see `man 8 saned` for details) - adds: `-l` (listen), `-D` (daemonize), `-o` (once), `-e` (stderr), `-u` (user) - removes: `-s` (syslog). Use `-a -d level -o -f` for the old behavior - changes: `-d` (debug). Use `-a -d level -o -f -e` for the old behavior - `saned` now cancels scans if the data connections appears to have gone away (after 4 seconds by default, configurable in `saned.conf`) - adds `--output-file` option to `scanimage` - adds `--help` option to `scan-find-scanner` - changes `sane-desc` to create relative hyperlinks ### Documentation - adds translations for Catalan, Hebrew and Valencian - updates translations for British English, Dutch, German and Ukrainian - marks unmaintained backends as such - documents USB workaround in `sane-usb` manual page ### Build - requires a C++11 compatible compiler for the `genesys` backend - requires a JPEG library when building the `pixma` backend - fixes unneeded linking when not using preloadable backend support - disables pthread support for systems with non-integral `pthread_t` type - fixes USB support detection on BeOS and OS/2 at `./configure` time - normalizes trailing whitespace in source code files. If you have local patches that no longer apply, have a look at the whitespace ignoring options of `patch` and `git apply`. New with 1.0.27 (see Note 1), released 2017-05-22: * Significant enhancements to canon_dr, epjitsu, epsonds, fujitsu, genesys, hp3500, pixma and xerox-mfp backends. * Minor updates, bugfixes or scanners added in several backends. * 30+ new scanner models supported. * Made libusb-1.0 the default for USB support (see Note 2). * Switched code from C90 to C99 (Thanks to Volker Diels-Grabsch). * Updated Linux USB3 workaround (see Note 3). * Documentation and translation updates. * Bugfixes (Avahi, threading, USB, ICC/PNG/JPEG, etc). * Reduced compiler warnings, improved code (see Note 4). Note 1: There is no 1.0.26 release of sane-backends. That number was skipped so that our development version numbers would more clearly be an extension of the prior release. This should make packaging a little easier for our downstream users. Note 2: On all systems, the --enable-libusb* flags are now ignored. Instead, the --with-usb and --without-usb flags now control support. When neither is given, USB support will be enabled if possible and disabled otherwise. If --with-usb is requested but not possible, ./configure will fail. There is no support to prefer libusb-0.1 over libusb-1.0. When libusb-1.0 is not found, libusb-0.1 will be tried. Note 3: The Linux USB3 workaround which was added in version 1.0.25 is now disabled by default. If you have difficulty using a scanner which previously worked, or intermittent scanner availability, try setting the new environment variable SANE_USB_WORKAROUND=1 before starting your frontend. Note 4: A special thanks goes to Olaf Meeuwissen for picking up the janitorial duties in sane-backends. He has found and fixed a large number of long-standing bugs, curated our bug tracker, improved our build scripts and docs, and provided user support. Thank you Olaf!
