0.1

First build to be tagged, and a pre-release on purpose: it works and is in
daily use, but there is no configuration yet beyond the slash commands.

What is in it

• Every single frame: player, target, pet, target-of-target and a boss
  column, built as an oUF layout.
• Five of the six design principles: class color at the edge, the portrait
  in its own column, power as a hairline, auras on a line the client colors by
  dispel type, and hatched absorbs with ghosted incoming healing.
• Two whole arrangements, /uuf layout classic and /uuf layout modern,
  switched without a reload and each remembering its own dragged positions.
• Frames that know about each other: dragging snaps to matching edges and
  refuses to drop a frame on top of what another one draws — its castbar and
  aura rows included, not just its box.
• /uuf check, a report window naming what this client hides from addons,
  in plain text you can copy out.

What is not in it

• No configuration interface. The layout set and dragged positions are the
  only saved state.
• No group or raid frames, and no range fading, which belongs with them.
• Only one thing on the list is written but unconfirmed in the client: a real
  damage absorb, which needs a shielded unit to point at.

Clients

Verified on Retail 12.1, and loading and drawing on the WoW: Forever beta
(interface 16001).

One package covers both. The attached zip carries both TOC files, and the
release.json beside it declares every interface they answer for — 120100 and
120105 for Retail, 16001 for Forever — so an addon manager picks the right one
by itself.

Forever writes its saved variables and never reads them back, so settings
do not survive a reload on that client. That is the beta, not the addon, and
the notes say why nothing here tries to work around it.

The full list of changes is in CHANGELOG.md.
