Bitcoin Scaling And How to Avoid Split?

SegWit2x is being deployed in its testnet to all working group members on July 14, and the period for live adoption starts on July 21, with an August 1 deadline for necessary support to avoid issues.

SegWit2x is competing with another proposal: BIP 148.

Developers have worked to make these two compatible, so, if enough mining pools support SegWit2x before August 1, bitcoin should avoid a split.
