- clean up webproxy getExtUrl
- bugfix init multicast on wifi reconnect
- add ip address of remote AP that's taken over a tag
- renamed button 'edit contentFS' to 'file system'
- apconfig: configure night time, where the system is not updating tags, and the tags are sleeping
- fixed bug calculating expected checkin
- throttle down apinfo update to once per minute
- fixed too many concurrent requests getting tagtypes
- resend current image when a tag reboots and the content type is 'static image' (all other content types were already regenerating the content)
- fixed timing of main loop
* Reduce code size by removing nullptr assignments
* Optimize tagDB for loops
* More tagDB optimizations
* Remove static from language arrays reducing RAM by 5128b
- Reduces Flash by 13060b
* Add missing extern in tag_db.h
* Fix deprecation warning of sntp.h
* Remove static from contentmanager, reduces RAM by 184b
* Use string reference in prepareDataAvail
- Remove some unneeded buffers
- Remove some gotos
- AP info screen content card. Can run on any tag.
- now, you can use {variables} in the 'text' entries in a json template. You can set variables via a http call. If you update a variable, all tags with a json template containing that variable get updated.
- font name in json template is more flexible. You can just use 'filename.ttf' or 'filename.vlw'. A full path is still possible.
- colors in the json template can now be set using #rrggbb color values, and using 'black', 'white' or 'red'.
- added direct output for the TFT display for the yellow esp32-s3. No file writes needed.
- added POST variable 'ttl' to json template upload and image upload, to set the next checkin time
- added /variables-demo.html to demonstrate the variables.
- json templates received from jsonupload are now saved in /current, and reused.
- known issue: 'backup db' button doesn't work due to some browser policy change. Fixing.
thanks to @steinwedel for the inspiration on the variables and some other fixes.
- new: tagtypes are be defined via json in /tagtypes instead of hardcoded
- content template is moved to the tagtype definition
- optimalisation of spr2buffer (also uses psram now, if available)
- bugfixes in spiffseditor
- size fix in painter screen for large screens
- fixed curves using intermediate points
- now uses ascender to find baseline
- now uses unitsPerEm for font size calculations
rendering is not perfect yet, probably mainly due to rounding issues
- clean up unnecessary files
- fix ota update, maybe preventing timeouts
- new 'wwwroot' folder for the web source files, and python script to gzip the files to the /data/www folder
- run gzip_wwwfiles.py to compress the files in wwwroot into /data/www
- small layout fix current weather on 4.2"
- qr code content enabled again
- turned off temperature on esp32
- http 409 on http POST during OTA
- finetuning buitenradar scale and refresh time
- follow redirects on jsontemplate http call
This one saves a lot of flash space.
Now, wifimanager is replaced with our own method for managing the wifi connections.
Also, the whole thing will run now even if there is no wifi. If wifi disappears, it automatically tries to reconnect in the background every few minutes.
Wifi settings now available at all times at /setup
If it cannot connect, an access point 'OpenEPaperLink' is created where you can set the wifi credentials (http://192.168.4.1/setup).
We currently have two ways of undefining the PowerPin in software for the ESP32
For once we can set POWER_NO_SOFT_POWER which will lead to some helpful screen
messages _but_ will still require the definition of the FLASHER_AP_POWER pin.
The second way (which was replaced with POWER_NO_SOFT_POWER) allowed to set the
powerPin array to {-1} to indicate that the pin is undefined. This would then be
handled in pretty far down the call stack right before toggeling the pin in powerControl:
```
void powerControl(bool powerState, uint8_t* pin, uint8_t pincount) {
if (pin[0] == -1) return;
```
This however is leading to an error: pin is n pointer (here an array with additional length)
to an uint8_t which can never be -1. Therefore the check wont ever be reached and an invalid
gpio number is passed to the gpio hal.
This caused the error:
```
E (XXXX) gpio: gpio_set_level(226): GPIO output gpio_num error
```
to show up in the logs.
We are now proposing three seperate changes to mitigate this behaviour:
1) We are addng the POWER_NO_SOFT_POWER to the Wemos and the M5Stack boards default configs
for new users to find.
2) We are replacing the pin[0] check in powerControl with a check on the pincount and a
nullptr check as the zbs_interface->begin() allows for no powerPin to be passed in which
case we are dereferencing a nullptr.
3) ZBS_interface->begin() is losing its powerPin related default configurations and
sanity checks are put in place before every calling.
We have opted to do 3) in this way and not adding the checked into the ZBS_interface->begin()
function which is also passed an uint8_t pointer to keep the API of the class stable
for reuse in other projects. Changing the interface however would be ideal here

The SPIFFSEditor.h header is being imported from the .platformio folder
while the corresponding .cpp is actually stored with the project.
To ensure we can not accidentally edit the wrong file in the future import
the header as well

When an SD Card is available it is the more interesing
metric in terms of space usage. We are therefore using
it here.

To be able to store more images and never worry about running
out of storage again we are adding support of SDCards.
We are faced with two options:
1) Remove the LittleFS code
2) Allow for both FSs but increase the app partition as we run
out of space.
We have opted for 2 for two reasons:
1) Unformated SDCards can be initialized from the littleFS
2) If the SDCard and the flasher share the same SPI pins
the SDCard needs to be completely disconnected so there needs
to be a FS in that rare case.
Performance wise the SDCard is not slowing the system down.
Writing the AP db with 70 APs takes 2.5 seconds, on the SD
only 800ms. This however is SD and setup depending.
By default the SDCard is expected on pins 18,19,23 however this
is configurable via preprocessor defines.
Globally we replace LittleFS with a new pointer to the currently
used FS allowing for hotswapping where the FS pointer is not saved.
One case which is therefore not working is the SPIFSEditor which
copies the FS interally.

- added Swedish å Å to Bahnschrift20 and 30
- option to turn dither on/off in 'static image'
- major overhaul of contentmanager.cpp, content is now generated from json template.
- fallback to 1bpp for 4.2" when no psram
- added 4.2" content layouts
- fixed small apconfig bug
- pause content generation for 60 seconds after crash, to prevent uncontrollable boot loop
- fonts re-rendered: added äöüßÄÖÜ.
- shuffled a bit with fonts to optimize disk usage
- ability to delete files during OTA
- prettify tagDB.json
- error handling in get_DB
- small cosmetic changes
* Due to new ability to delete files: After firmware update via OTA, please perform an OTA update of the filesystem again to perform the deletion of unneeded fonts.
* If updating via platform.io: don't forget to update the filesystem image.
