Bootstrap to drop IE support
The decision to drop IE support is projected to decrease CSS, which will be beneficial to everyone, according to Bootstrap.

“Dropping IE support isn’t something we decided to do out of spite or something; it really allows us to improve things for everyone else. And by seeing the numbers, the people that will benefit are multiple times more,” the developers behind Bootstrap said. 

V4 will be supported for quite some time which means people who want to support IE can still use this version, like people could use v3 after v4 was released and we kept supporting it for a long time.

To enable customers to identify systems that depend on these deprecated features, before the final turndown date is reached, there will be scheduled downtime for Global Batch and JSON-RPC starting from February 2020 and running through August 2020, Google stated.
