@feanil @kdmccormick
Can you guys please merge this as its blocking this PR. Also remove Python 3.8 from settings

[farhan]

@OmerBhatti Once the Python dependencies PR merges, rebase this PR branch, resolve conflicts if required.

[Agrendalath]

We're dropping Python 3.8 support here, so we should make the major version bump in image_explorer/__init__.py and indicate in commit messages that this breaking change is incompatible with releases older than Redwood.

@Agrendalath looks like your comment has been addressed, can you resolve?
