Amazon EventBridge event matching now runs on Open Source Event Ruler v1.50, enabling advanced filtering capabilities such as combining anything-but filtering (matching anything except for the value) with suffix filtering (matching against characters at the end of a value), and equals-ignore-case filtering (matching against a string regardless of case). For example, you can now match against values that don’t end with a specific file type such as .png or .jpeg. You can also combine prefix filtering (matching against characters at the beginning of a value) and suffix filtering with equals-ignore-case filtering.
