Previously, some filter operator did not work for numbers or had only a special meaning with certain columns. This has been generalized in a uniform way, so all operators work for numbers now, too.

The operators ~, =~, and ~~ interpret numbers as bit sets, and have the following meaning:

  • x ~ y means: x is a superset of y
  • x =~ y means: x is a subset of y
  • x ~~ y means: x contains at least one element of y

This is consistent with the way attribute list columns work and makes the Livestatus semantics more regular.
