CrossInk Academic v1.6.1

CrossInk Academic v1.6.1 is the academic firmware release built from the
jbfarias/CrossInk-academic repository. The complete source code is available
in the main branch and at the v1.6.1 tag.

What is included

  • Academic notes and highlights backed by the document-safe NoteStore.
  • EPUB clippings with bookmarks, full-text preservation, migration support, and
    content-derived document identity.
  • User-defined annotation tags for clippings and pages, with tag-aware
    exports and the web /highlights page for searching, editing, tagging, and
    exporting annotations.
  • The same academic annotation feature set in every device build: X3/X4,
    X4 Pro, and Sticky.
  • CrossInk Academic branding in the UI, translations, startup identity, and
    the X4 Pro USB descriptor.

Select the file that matches the hardware. Do not flash an X3/X4 or Sticky
image to an X4 Pro; the X4 Pro uses a different ESP32-S3 hardware profile.

Improvements reviewed from upstream discussions

The release keeps the compatible improvements already present in the academic
base and incorporates the applicable robustness fixes reviewed from
CrossPoint Reader discussion #3099
and CrossInk discussion #600:

  • X4 Pro display, touch, Home-key, USB storage, frontlight, and simulator
    compatibility.
  • Transparent sleep-overlay handling with low-memory font-cache cleanup.
  • EPUB ruby-group continuation handling and tolerance for trailing data after
    a closing </html> element.
  • Existing reader improvements including dark mode, dictionaries, quick
    actions, XTC/table handling, touch gestures, and clipping reliability.

Installation

  1. Download the binary for the device from this Release.
  2. Verify its SHA-256 checksum if transferring over an untrusted connection.
  3. Flash it using the CrossInk/Inky web installer or the device's documented
    USB/SD update workflow.
  4. Keep a backup of the .crosspoint directory before upgrading if the device
    contains important notes, clippings, or tags.

The source tree, changelog, installation guide, academic integration notes,
and OTA catalog are included in the repository at the v1.6.1 tag.
