will this still be maintained?

[DanielRuf]

There are many who use this library. It would be not so great if this project would not be further maintained.

gantt-schedule-timeline-calendar is just like next major release (v2) of gantt-elastic but with different name
gantt-elastic cannot be maintained because of bad decisions in the core structure - there is a lot troubles with performance and when it comes to adding new features

[neuronetio]

of course some minor bugs of gantt-elastic will be fixed but with slower response time right now
