Groovy contains the fix for "&" and "$"
Focal contains the fix for "$"
Eoan contains the fix for "$"
Bionic contains the fix for "$" (without the mem alloc changes since they're not needed and SRU would likely not accept those without a specific test case for them).
More information can be found in the merges linked to this bug.
