[ildyria]

• Slideshow is now fully integrated and functional. See our demo : https://lychee-demo.fly.dev
  Open any album, top right there is a play button.
  Also open a picture, press space and it will start, still responding to left and right options.

• Timeline feature: now fully available per album. Single timeline needs to be implemented.
  Customization of the type of granularity is also possible (per day/month/year) at album and photo level.

• Duplicate Handling is now fully functional with quick delete photo button, search on photo checksum or photo title. Possibility to restrict findings per album (strongly recommended when doing title collision).

• Docker Installation has been improved with two docker compose files:

  • full setup: https://github.com/LycheeOrg/Lychee-Docker/blob/master/docker-compose.yml
  • quick deploy with caddy: https://github.com/LycheeOrg/Lychee-Docker/tree/master/configuration-with-caddy
