The popup rendered the day each release went out, which gave the office
a way to ask what was done on a given day. Each release now shows its
number and the short SHA it shipped with, and the date-shaped version
string is gone from the registry.
The date formatter is deleted rather than hidden, so no code path can
put a date on screen, and a test fails the build if one comes back.
The 'seen' marker moves from the version string to the release number,
so the badge lights up once for everyone on this deploy and then
settles.
The version strings are dates ("2026.11.01"), so a release has no
identity that is not a date. Every entry now also carries a release
number and the short SHA of the commit it went out with.
The date-shaped version string is left in place for now — the popup
switches over and drops it in the next commit, so this one stays
green on its own.
A test holds the numbering unique, contiguous and newest-first, and
holds every commit to a real SHA.
The sidebar's bottom block gets two new controls:
- A "What's New" button that opens the release-note popup, with a badge
until the operator has read the latest release.
- A Dark Mode section that replaces the old one-click toggle with an
explicit Light/Dark switch, so the current mode is always visible
instead of being inferred from the button's label.
The theme colour picker stays in Settings -> Appearance; the sidebar
carries the mode switch only, so the nav rail is not a strip of 16
coloured squares.
