Improvements

• Websocket commands optimized in sense of memory consumption.
• The size of the display in the Display web page will be automatically adapted.
• File upload dialogs filter now for the appropriate file extensions.
• Bitmap (.bmp) V5 header support added.
• Virtual buttons controlled via websocket or REST API can execute all defined button actions.
• The display page was extended to jump to previous/next slot.
• The AsyncHttpClient's serialized to have only one outgoing http/https request at a time. This was necessary because a single https request needs about 47 kByte of heap memory and may cause a reset depended on the users configuration and timing.

Bugfixes

• NTP address handling fixed, which could cause a broken time synchronization.
• Several small bugfixes.

DDPPlugin

• DDP protocol fixed to be used by e.g. xlights.

Notes

• Please have a look to the REST API v1.4.0 for new functionality.
• To get all Pixelix features you need a development board with at least 8 MB flash and a dual core ESP32 chip.
• On a single core ESP32-S2 it may happen that artifacts in the display appear in case of requests to the webserver. Note the LwIP stack and the TCP layer has tasks with higher priority and may access intesively the filesystem.
