19 Upgrade notes for 3.4.9

Item changes

  • web.page.get[], web.page.perf[] and web.page.regexp[] items now turn unsupported if the resource specified in the host parameter does not exist or is unavailable. For more details, see Zabbix agent items.

Trigger changes

  • Trigger expression's behavior regarding numbers, differing by 0.000001, is now changed. Since logical operators are defined in terms of equality to zero, their result for 0.000001 is affected too:
Expression (Example) Evaluation result
Before After
1.000001 > 1 1 0
1.000001 <= 1 0 1
0 >= 0.000001 0 1
0.000001 <> 0 1 0
0.000001 = 0 0 1
0 or (1/1000000) 1 0
not (1/1000000) 0 1
1 and 1/1000000 1 0
