[istankovic]

We need to review changes made to the 0.x branch (listed below) and cherry-pick those that make sense to the main branch. ~- [ ] addc630ef613826d3d6a90a6c4453c39aba5cfcf Release v0.1.6~
~- [ ] 33b6f64ef44335ae3d6f8fbceea3f9306ac32efc Update CHANGELOG.md~

~- [ ] 04c1c692ca06fdd78fd612a360ae6db6ccca9a05 beamer: allow request transition l1_resolved -> l1_resolved [try_to_claim]~ (this is not necessary on main since, as of very recently, we do not allow challenges once L1 resolution is done)
