Release v7.1

weewx-celestial 7.1

A small quality release: when the page cannot fetch its loop data, it now
says so on the page instead of sitting silently dead. Drop-in upgrade
from 7.0 — install over it, no uninstall, no config changes.

What's new

• A failed loop-data fetch shows up in the badge. When the poll for
  loop_data_file returns anything but the json — the classic case being
  the web server's 404 page, because weewx-loopdata writes outside
  HTML_ROOT (say /dev/shm) and nothing on the web server serves that
  path — the LIVE badge now reads NO DATA (HTTP 404) — check loop_data_file (or BAD DATA — check loop_data_file for a response
  that isn't json). A network-level failure or timeout shows OFFLINE.
  Previously the only trace was a JSON.parse error in the browser console,
  and the page just looked dead. A later successful poll rewrites the
  badge to LIVE, as always.

Requirements

• Python 3.9 or later, WeeWX 5.2 or later
• weewx-loopdata 5.0
  or later (evaluates the almanac fields)
• weewx-skyfield
  strongly recommended: it computes every position and distance the panel
  runs on, and only its almanac serves Proxima Centauri. PyEphem serves
  everything but Proxima; with neither, the page generates but the panel
  shows an install hint.
• Skyfield and NumPy are not required by this extension.

Installing/upgrading

From 7.0: download weewx-celestial.zip from this release, then
weectl extension install weewx-celestial.zip and restart WeeWX — 7.1
ships exactly the same file set as 7.0, so installing over it updates
everything and orphans nothing.

From 6.x or earlier: follow the 7.0 release notes' action-required steps
first (uninstall before installing, fields line, possible data_services
cleanup), using this release's zip.
