What's New in 1.8.2

:: Dashboard filtering

Dashboard supports filtering based on host groups, trigger severities and host maintenance status.

:: Improved speed of synchronization for distributed setups

It works much faster especially for larger setups.

:: New option for host mass update

Template "replace" option added for easier maintenance of template linkages.

:: Improved performance of Zabbix front-end

Better performance and lower memory usage introduced for many front-end screens.

:: Added support of time shifted functions

Now some trigger functions (min, max, avg, and other) functions support optional time shift. Use it and make your triggers and logic much smarter!

:: Added Ukrainian translation

We welcome all Ukrainian users!

:: Added time-based disabling of data collection on item level

Default interval of '0' with flexible intervals may be used to enable data collection within specific time periods only.

:: Support of suffixes in trigger expressions

Triggers expressions and functions support s,m,h,d,w,T suffixes.

:: Enhanced screen element "Status of triggers"

It supports optional filtering by a selected host or a host group.

:: Added support of multiple host groups for aggregate checks

A list of host groups can be passed as a parameter to aggregate checks.

:: Better permissions on actions

Administrators have access only to users they share user groups with.

:: The database is down message is supported for all DB engines

Now Zabbix correctly processes unavailability of the database engine. It works for Oracle, PostgreSQL and MySQL.

:: XML import and export of screens and maps

Finally we have a way of managing screens and maps based on XML data.

:: Added information about maintenance to the Dashboard

The Latest Issues widget provides information about host maintenance status.

:: Better time navigation

Time navigation bars moved to the top of the pages with hide option.

:: Enhanced control of housekeeper settings

A new parameter MaxHousekeeperDelete was introduced to allow much more flexible control over housekeeper behaviour.

:: Zabbix sender supports reading of data from standard input

A new command line option enables reading of performance and availability data from standard input.
