chore(deps): Upgrade dependencies that can be upgraded simply

[joshlarson]

Scope

Asana Ticket: 🛠️ (2026/09) Upgrade Dotcom Dependencies

Implementation

I used mix hex.outdated to find the versions that were out of date, and tried upgrading them to their latest versions. Most Just Worked™. There were some exceptions...

Exceptions

We already are not upgrading mail due to a bug in later versions of the library, and nebulex requires a complicated and sparsely-documented upgrade that we haven't had time to do yet.

For each of ecto, html_sanitize_ex, phoenix, phoenix_live_view, and req, a naive upgrade would have either caused compilation errors, runtime warnings, or test failures, each of which is likely simple, but not trivial, to address. I created follow-up tickets to handle each of those upgrades separately. Of those, ecto is stuck on its current version due to a shared dependency with poison, a library that we're planning on removing from our dependency tree, but haven't actually removed yet. The others are likely not blocked on anything.

How to test

mix hex.outdated | grep -v Up-to-date should show the following output:

Note

This is in draft until #3486 is merged, since it builds off of the Elixir language version upgrade in that PR.

Depends on:

• chore(deps): Upgrade Elixir to 1.20.4, and upgrade some deps whose old versions are now incompatible. #3486
