- Update to version 1.4.0:
+ The ability to use the write()/read() interface of i2c-dev has been restored.
It is needed to work around a bug in the proprietary nvidia driver. By
default, the write()/read() interface is used for the nvidia driver, the
ioctl() interface is used for all other drivers. Command line options
***--use-file-io*** and ***--use-ioctl-io*** affect his default behavior.
When i2c-dev's file io interface is used, option ***--force-slave-address***
is again meaningful.
+ Option ***--sleep-multiplier*** and API functions **ddca_set_sleep_multiplier_value()**,
**ddca_set_default_sleep_multiplier_value()** now accept 0 as a valid
argument.
+ The ddcutil command parser reports an error if a display selection option
(e.g. ***--bus***) is given on a command to which it does not apply.
+ Write additional error and information messages to the system log.
+ Eliminate message "Is DDC/CI enabled in the monitor's on-screen display?"
It's rarely the cause of communication failures.
+ Warn of a possibly invalid DRM connector name in **detect** output if
monitors with identical EDIDs are used with the proprietary nvidia driver.
+ Handle /dev/i2c device names with a double hyphen, e.g. /dev/i2c--3.
+ Better libddcutil handling of configuration file errors. Do not abort
initialization in case of errors.
+ Fix interpretation of digital display type bits for EDID version 1.4
+ Miscellaneous segfaults.
