Looking at the list of Yul transformations in the documentation, I noticed a few slight differences between the list at https://docs.soliditylang.org/en/latest/yul.html#optimization-step-sequence and the list at https://docs.soliditylang.org/en/latest/internals/optimizer.html#optimizer-steps:

Issue
The "Full Example" of using @truffle/contract to interact with contracts should include an example of listening to an event with a filter.
