  ef-1.0.5 - Stability & Memory Improvements

  This release focuses on webserver stability, memory optimizations, and integrates two upstream features.

  Highlights

  • Sunlight Fading Fix - New toggle in Display settings to turn off the display between refreshes, mitigating the e-ink fading issue when reading in direct sunlight
  • File Transfer Stability - Major improvements to webserver reliability during file listings
  • Memory Optimizations - Reduced memory pressure in WiFi scanning and QR code generation

  Bug Fixes

  Webserver

  • Removed blocking MD5 hash computation from file listings that caused EAGAIN errors and connection stalls
  • Implemented 2KB batch streaming for file listings with pacing to prevent TCP buffer overflow
  • Simplified flow control by removing unnecessary yield/delay logic

  Memory

  • QR codes now generated once on server start instead of regenerating on each screen render
  • WiFi scan: replaced std::map deduplication with in-place vector search, limited to 20 networks
  • Fixed 48KB memory leak when navigating from Home to File Transfer

  EPUB Reader

  • Fixed words before styled inline elements incorrectly receiving the element's style (errant underlining)

  Flashing Screen

  • Fixed version string parsing failing on longer version strings
  • Changed to half refresh for cleaner appearance

  Upstream Merges

  • PR #522 - HAL Abstraction Layer: Introduces HalDisplay and HalGPIO classes
  • PR #603 - Sunlight Fading Fix: User-toggleable setting in Display settings

  Installation

  Flash firmware.bin to your Open X4 device using the web flasher or esptool.
