It is now possible to display them in the bottom section * Added image pre-processing operation to allow displaying the generated image correctly on the E-Paper * Added limit (in days) when fetching events from the iCalendar * Added option to select the display-update interval* * Added user-friendly Web-UI (webpage) for entering personal details easily (Credit to TobyChui) * Added support for continuing the loop even if some details are missing in the settings file (api-key, rss-feed) * Added support for relative path and removed explicit path * Added support for timezones. events timings will be shown correctly using the system's set timezone * Added support for 12/24 hours format for events ### Changed * Changed E-Paper layout by splitting the image into three section: top-, middle, bottom. * Changed the way the installer checks if a required package is installed (by test-importing it in python3) * Changed the function which displays text on the Calendar * Merged e-paper driver files (initially epd7in5b and epd7in5) into a single one (e_paper_drivers) * Switched from image-based translations to text-based translation * Changed algorithm for filtering events ### Removed * Removed (older) fonts which were not suitable for multiple languages * (Temporary) removed support of recurring events due to some known bugs * (Temporary) dropped support of the installer on Raspbian Jessie Lite due to some known bugs * Removed image-based translations for month names ### Fixed * Fixed problems with iCalendar triggers by removing them altogether when parsing the iCalendar * Fixed problems with outdated events (*) Updating too frequently can cause ghosting, a problem specific to E-Paper displays where parts of the previous image can be seen on the current image. Ghosting can be fixed by 'calibrating' the E-Paper (displaying a single colour on the entire display) and is done by default. As a rule of thumb, one 'calibration' should be done for every 6 display-updates to maintain a crisp image. ## [1.5] Early February 2019 ### Added * Added option to update or uninstall the software via the Installer. To uninstall, just re-run the Installer. * Added feature to display upcoming events from the current month and next month on the bottom section. * Added support for 12 hour/ 24 hours (sunrise- and sunset-timings can now be adjusted via the settings file) * Added support for imperial units (wind speed can now be shown as mph as well) * Added option to choose metric/imperial units * Added option to save the generated image in the 'Calendar' folder to help debugging. ### Changed * Changed a lot of icon sizes, positions and locations. * Changed the file format for nearly all icons.
