Each page in a schedule block, and each rule that adds its page to the
rotation, has a "skip in slow mode" checkbox. While slow mode is on those
pages are left out of the rotation; when none of the block's pages are
left, the chosen page is shown. The rotation keeps its own timers.
Schedule format version 5; version 4 is converted when read and stored
again in version 5 on the next save.
Version 2.18.0.

A new page element runs Conway's Game of Life in an area (the whole display
by default), one per page. Start: random dots, one pattern, or the icons
whose names start with a text in turn or in random order. Edges: wrap
around, dead, or a hidden margin where gliders fly out of view (leftovers
that stay put in the margin are cleared, so a glider gun runs cleanly).
It restarts when the board is still or repeats within 16 generations
and/or after a number of generations, after a hold time (an empty board
at once).
logic/life holds the board and timing (tested), display/life_player runs
the board of the shown page, ticked before each frame; frames are paced
like scrolling text. The element reuses existing fields, so the page
format stays the same. The Icons tab has a library of 17 LifeWiki
patterns (checked with a simulation), and the built-in page "Game of
Life" shuffles through the life_ icons. About 12 KB flash, 8 KB RAM.
Version 2.17.0, tested on the display over OTA.

Slow mode (Home Assistant switch "FlipDot Display Slow mode", dropdown
"FlipDot Display Slow mode interval", web UI Settings) makes the display
change only every 1, 2, 5, 10, 15, 20, 30 or 60 minutes, on the clock, and
powers it off in between: less noise. Nothing else is drawn meanwhile, also
no page changes. It updates at once after boot, the night, the Power switch
and live mode, and when it is switched off. Rules can override it ("show at
once in slow mode"): while their page is shown the display works normally.
Settings layout 7 and schedule layout 4 (older records are converted; they
are stored again once the firmware is marked good, so a rollback still
finds the old ones). Pages in older formats are rewritten in the current
one, in time-boxed steps. /api/status reports old_data_left.
Version 2.15.0.

Pages choose their own refresh effect (or the Hardware setting), used when
the page appears and for its own changes. Schedule blocks that switch
instantly and rules still switch instantly. The ESP32 sends page effects
to the Nano with a new no-save flag (E ...,2), so page switches don't wear
the Nano's EEPROM. Page format 7 (version 6 pages are converted).

- Home Assistant attributes can be paths into lists (forecast.1.condition).
- Date elements can show a day ahead (day offset 0-7).
- Pages hold 16 elements (page format 6; the old formats are frozen at 8).
Pages are reset in place (clearPage), not through a 4 KB temporary.
- Verwachting page: today (icon, temperature, max/min) and the next 2
days with 7 x 7 icons (weer7 <condition>), from a template sensor
(docs/home-assistant.md).
- examples/home-pages.json is exported from the display with all pages
and their icons, private entity id parts replaced by placeholders
(tools/export_examples.py replaces tools/make_example_pages.py).

Stored as icons at boot from the firmware's bitmaps (cut to 80 x 19), so
they can be edited; the firmware copies stay the fallback.

- Rules: "also over a page chosen by hand" (on by default); off, a rule
waits until the manual pick ends. Schedule store version 3, version 2
records are read with the option on.
- The Clock page is stored at boot from the built-in one and can be
edited; Reset (deleting it) brings back the original.
- Home Assistant attributes were never found: ArduinoJson 7.4 takes a
char array key as a literal of its full array length.

Bitmaps that only pages use (backgrounds, images by state) are now icons:
own width and height, stored in /icons, not in the page lists or the Home
Assistant dropdowns. Page backgrounds and image elements use icons or
bitmaps; the renderer gets icons expanded at the top left, so pages look
the same. Web UI: Icons tab with an editor, Make icon / Make bitmap, Save
as icon on the Draw tab, icons in the backup.
A one-time migration in time-boxed steps moves the uploaded bitmaps that
only pages use, after the new firmware is marked good.

scroll_speed is now a float (0.05-30 dots per second, e.g. 0.25 = one dot
every 4 s). Page format 5; version 4 pages are converted, version 3 goes
through version 4.

- net/ha_api: the HTTP requests run in a FreeRTOS task on core 0; loop()
only hands over copies through queues. The web UI's test button polls.
No more 3-4 s loop() stalls once a minute; timeout raised to 5 s.
- Progress bar page element (page format 4, v3 pages are converted)
- Plex user setting (settings v6): {plex_user} in entity ids
- Plex page (examples): watchers, play/pause icon, title, progress
- Bitmaps cached in RAM: a LittleFS read took ~100 ms on every render
and web preview; long JSON lists sent in 2 KB pieces
- Backup includes the refresh settings and the Plex user

The Nano's periodic full redraw blocked for ~0.8 s. A frame that arrived
meanwhile overflowed its 64-byte serial buffer; lost bytes in a bitmap
shift the rest of the image (picture moved up), and diff frames never
repaired it.
- Nano: all drawing (frames, effects, the dot refresh) runs from update()
in ~1 ms slices; the refresh pauses while a frame is received or shown
- New commands: C (reply with the image checksum) and I (refresh minutes,
EEPROM)
- ESP32: NanoMonitor asks for the checksum after frames and sends the whole
image again on a mismatch, missing answer or Nano restart; counts ERR
replies. Periodic whole-image resync.
- Settings: "Dot refresh" and "Image resync" intervals (settings v5,
v4 records are migrated)
- System tab: loop timing, free memory, frame check counts
- test_driver: the real driver against a simulated panel

- README is the overview; web UI, pages, Home Assistant, how it works,
wiring, Nano over WiFi and the recovery app have their own page in docs/.
- docs/web-ui.md has a screenshot of every tab, made with headless Edge by
tools/make_webui_screenshots.py.
- The web UI opens a page in the editor with #pages/<name>. Version 2.7.2.
- The reply wire is fitted (flashing the Nano over WiFi works).
