The Nagios Plugins Development Team is proud to announce version 1.5 of the Nagios Plugins! This release comes with the new check_dbi plugin written by Sebastian Harl, and includes lots of enhancements and fixes provided by more than forty contributors. Many thanks to all of you!

Special kudos go to Sven Nierlein for fixing numerous bugs, reviewing many pull requests, bringing our test suite back into shape, and setting up automated tests on a variety of platforms. This helped us spotting lots of bugs before the release. Let me also thank Ton Voon for doing the unenviable work of updating the bundled Perl modules; and our newest team member Jan Wagner for all his help with patch review.

See below for a list of major changes. Note that the new check_http version introduces two minor backwards incompatibilities mentioned at the end of that list, so please be sure to check whether they might affect you.

You can get the tarball from our download page.

Fixes

• Change the MAIL FROM command generated by check_smtp to be RFC compliant
• Fix compilation of check_http without SSL support
• Fix check_snmp reversed threshold ranges (backward-compatibility)
• Fix check_snmp memory violation when using more than 8 OIDs
• Fix check_apt security regular expression
• Fix check_http handling extra header (-k) containing semicolons
• Fix check_apt handling unknown exit codes from apt-get
• Fix deprecated imports of check_nmap.py

Warnings

• check_http behaviour of -k/--header changed since it does not separate multiple headers by semicolons anymore. Use multiple -k switches instead.
• check_http‘s --proxy_authorization option is now called --proxy-authorization (it was always documented this way)
• The contrib directory has been removed. These days, sites such as Nagios Exchange serve as much better places for publishing plugins not maintained by the Nagios Plugins Development Team.
