    listed here.
-   *Monitoring → Latest data* section gains a new filter to show items

#### - Zabbix server improvements

Zabbix server performance has been improved when calculating trigger
expressions.

The processes that take values from history cache and put them in the
database - **history syncers** (configured by the server configuration
parameter **StartDBSyncers**) take up to 1000 values on each iteration
and calculate all triggers that reference corresponding items.
Previously, each [trigger
function](/manual/config/triggers#trigger_functions) would result in a
separate query to the database. Starting with Zabbix 1.8.8, a single SQL
query is prepared for all of the functions in all triggers that history
syncer has been tasked with updating.

Additionally, if there are multiple triggers in such a batch that check
text or log items, last two values for items like those are cached for
the current run.

In total, this results in a significantly decreased query count against
the database and thus performance improvements.

The same improvements also affect the internal **timer** process (only
one such process may run currently), which calculates triggers that
include [time based
functions](/manual/config/triggers#time_based_functions).

History syncers try to take a new batch of values from the history cache
0-5 seconds after they have finished the work on the previous one, based
on how many values it got previously (for example, if it got 1000
values, it will make the next attempt immediately after finishing the
work).

### - General improvements

Macro **{TRIGGER.ID}** is now supported in frontend and notifications if
used inside trigger URL field.
