Release v6.6

weewx-loopdata 6.6

Almanac fields can now pin their units, attribute chains walk exactly
as Cheetah walks a report tag, the French translation is out of
Beta, and a complete Dutch translation ships (Beta). Drop-in upgrade —
install over 6.x; no configuration changes,
and every existing fields line produces the same values as before.
Released alongside weewx-celestial 7.5, whose migration utility now
emits the pinned spellings.

What's new

• Unit segments on almanac fields. Almanac fields complete the
  grammar: like observation fields (day.outTemp.avg.degree_C) and
  station fields (station.altitude.meter.raw) before them, an almanac
  field can carry a unit segment: almanac.sunrise.unix_epoch.raw,
  almanac.sun.visible.second.raw,
  almanac.sun.visible.hour.round(2).raw (the unit sits before
  round(n) and the format spec). It pins the unit no matter what the
  target report's unit settings say. Without one, .raw follows the
  target report's converter — by design, that is report-tag parity — so
  a target report with [Units] [[Groups]] overrides (say
  group_deltatime = hour) turns almanac.sun.visible.raw from seconds
  into hours. Pin the unit on any .raw field your javascript consumes
  numerically. The manual's
  Almanac fields page
  has the full story.

• Cheetah-exact attribute walking. Almanac and station field chains
  now auto-call exactly as Cheetah's NameMapper walks a tag: a segment
  that resolves to a method or function is called at every dot, not only
  at the end of the chain, and a callable instance is never auto-called
  (Cheetah leaves those alone). Concretely: under weewx-skyfield ≤ 1.14,
  almanac.moon.parallactic_angle.degrees worked as a report tag but
  failed as a loopdata field; now both behave identically.

• French is out of Beta. lang/fr.conf has been native-speaker
  reviewed, in step with weewx-skyfield's and weewx-celestial's reviewed
  French (a test keeps the three extensions' shared vocabulary
  identical). Select it with lang = fr on the report's stanza.

• Dutch ships (Beta). lang/nl.conf is a complete Dutch
  translation of the sample report — gauge headings after the Dutch
  labels of WeeWX's own Seasons skin, the nine trend.barometer.desc
  descriptions in the tendency vocabulary of Dutch weather reports
  (stijgend, gelijkblijvend, dalend), and, for a loopdata
  instance whose target report is Dutch, the compass ordinates, moon
  phases, body and all 88 constellation names — the shared vocabulary
  in step with weewx-skyfield's and weewx-celestial's Dutch (the same
  cross-repo test that pins the German and French). Select it with
  lang = nl. Beta pending native-speaker review — corrections
  welcome.
