v4.4.0

• Support for Vision Master E213 and E290 boards
• Fix setting rotation inside a DRAW() operation
• Softer fast-mode refresh for DEPG0290BNS800

PlatformIO users:
You now need to have the "official" Heltec board identifiers added to the build_flags line of your platformio.ini file.
See the example here.

v4.3.2

Increased contrast / decreased ghosting when using fast-mode with LCMEN2R13EFC1 (Heltec Wireless Paper V1.1)

v4.3.1

Quick bug-fix release:

• work around a conflict between Heltec_EPS32 library and IDF 5.1 component (#12 (comment), @Glenno-H)

v4.3.0

Feature:

• Dimension info moved:
  • display.bounds.full.x() -> display.x()
  • display.bounds.window.x() -> display.window.x()
  • etc.

Fix:

• Building for Wireless Paper with the new Heltec ESP32 Series develop environment Rev 3.0.0 Alpha (#12, @vinouz)

v4.2.0

Feature:

• Preserve fast-mode image after process sleep: disable memory init with arg. fastmodeOn(false) (#11, @allllo20)

Fix:

• customPowerOn() broken on some platforms

v4.1.2

Fix:

• Fast-mode for GDEP015OC1 and GDE029A1 (2beb1d4)

Refactor:

• Fast-mode settings adjusted for DEPG0150BNS810, DEPG0154BNS800, and LCMEN2R13EFC1 (ebc7ee3)

Doc:

• Minor errors corrected in examples (d9c49af), (82c52fc)

v4.1.1

Fix:

• Building for ESP8266 (5f629d3)
• Reduce "image noise" at screen border, during fastmode, for DEPG0213BNS800 (523defb)
• setBackgroundColor() fills memory with color, when using update() (9ab232c)

Doc:

• New example for Wireless Paper: download.ino (57e9055)
• New observation: some of the LCMEN2R13EFC1 Wireless Paper boards now have a sticker, showing "V1.1". (05c895c)

v4.1.0

• printCenter() method for placing text at / near display center
• drawing config (e.g. setCursor()) is now honored when called before DRAW()
• additional examples

v4.0.1

Fix:

• Examples: wireless_paper

  Folder structure was incompatible with Arduino IDE (but working in PlatformIO).
  This broke critical "out of box experience" for Wireless Paper users

v4.0.0

Features

• Support for "Wireless Paper" boards
  • DEPG0213BNS800 (Marketed as: "E-INK V1.0")
  • LCMEN2R13EFC1 (Marketed as: "E-INK V1.1")
• setRotation() accepts several new formats
• Load and Save from SD with "prefix" and "iterable id"

Fixes

• Fast mode: no longer causes a "double update"
• Fast mode: LUTs reviewed
• Fast mode: update() no longer erases image-data generated before fastmodeOn()
• Fast mode: "Border" set for DEPG0150BNS810
• SD: 2.13" displays now save data as 122px wide
• SD: images loading direct from SD can now use fast mode
• SPI: clock speed increased from 200KHz to 2MHz
• Sketch size: optimization.h - less flash usage on Uno
• Bluetooth: resolved compatibility issue with ESP32 BLE library
• Text: getTextBounds() working for 32bit platforms
• Text: setCursorTopLeft() working for 32bit platforms
• update(): no longer overrides setBackgroundColor(), setTextColor() on first call
