## Enhancements

* `check_nt` `UPTIME` accepts warning/critical thresholds
* `check_disk_smb` now allows spaces in share names
* `check_http` now uses standard threshold functions (enables floating point and ranges)
* `check_http` now checks for and prints the certificate cn (hostname) in SSL certificate checks
* `check_http` now supports an optional `-S/--ssl` value to choose the SSL protocol version
* Add perfdata to `check_ssh`
* New option to `check_smtp` to ignore failures when sending `QUIT`
* New `check_by_ssh` `-F` option which allows for specifying an alternative `ssh_config(5)` file
* `check_sensors` now detects faulty sensors unless `--ignore-fault` is specified
* utils.sh now provides a `check_range` function
* Improved the performance of `check_users`
* Add perfdata to `check_disk_smb`
* Updated Nagios::Plugin perl module
* Add warning threshold to certificate expiration checks of `check_tcp`/`http`/`smtp`
* Add `--perf-oids` option for `check_snmp`

## Fixes

* Fix `check_disk` free space calculation if blocksizes differ within a disk group
* `check_disk_smb` now handles `NT_STATUS_ACCESS_DENIED` properly
* Make `check_snmp` work more like v1.4.14 with regard to using special values (Timeticks, STRING) as numeric thresholds
* Fix `check_ldap` overriding the port when `--ssl` was specified after -p
* Fix `check_procs` where regex input of '|' would get displayed in output - now replaced with ','
* Fix segfault in `check_host` when hostname returns multiple IP addresses
* Fix `check_smtp` and `check_tcp` where duplicate messages were displayed for certificate errors
* Fix `check_ping`'s parsing of `ping6(1)` output
* Fix a `check_dhcp` bug which was triggered by checking Windows 2003 DHCP servers
* Disable RFC4507 support, to work around SSL negotiation issues with (at least) some Tomcat versions
* Fix performance data label containing spaces in `check_snmp`
