Why this matters. Changing the rules of a live blockchain is dangerous. Get it wrong and two versions of the network can disagree, or a transaction meant for one chain can be copied onto another. Before Overwinter, Zcash had no standard, replay-safe way to coordinate a rule change. Overwinter fixed that. It gave Zcash a formal process for upgrades and, just as important, two-way replay protection, so a transaction that is valid under one set of rules cannot be replayed under another. That groundwork is what made Sapling, and every upgrade after it, possible to activate cleanly.

ZIP 203 Ụlọ ọrụ added transaction expiry. A transaction can now set an expiration block height. If it has not been mined by that height, nodes drop it from the mempool, the waiting room of unconfirmed transactions. Before this, a transaction could sit unconfirmed for a long time. Expiry means a stuck transaction eventually clears on its own, which reduces uncertainty for you and keeps the mempool from filling up with old, unmined transactions.
Ebe ọ dabara adaba .
Overwinter was the first Zcash network upgrade after the October 2016 mainnet launch, and it shipped deliberately ahead of Sapling. Its job was infrastructure, not features. By installing the upgrade mechanism and the replay-protection machinery first, it gave every later upgrade (Sapling, Blossom, Heartwood, Canopy, NU5, and the ones after) a safe path to activate.

Answer
Because it built the machinery that every later upgrade depends on. Overwinter introduced the Network Upgrade Mechanism and two-way replay protection, giving Zcash a standard, safe way to change its consensus rules. Without that groundwork, Sapling and the upgrades after it could not have activated cleanly.
