v2.9.3

Recommended Upgrade

Optional, yet recommended upgrade which includes a number of small fixes including long-standing stability and memory issues that were caused by the SPV. In particular, this fixes many occasional crashes that may appear as IO errors which were caused by the SPV code closing incorrect file descriptors, resulting in the corruption of the blockchain database.

Upgrade Notes

• For nodes >= 2.9.1, this is a drop in upgrade. No reindex required.
• For nodes that are being restored from recent snapshot, as with all updates before: -rescan for the wallet txs and additionally -spv_resync for users who hold BTC. If either isn't used, they may not be shown in the wallet until rescanned/resynced.
• For other nodes, one of the following is required: a fresh sync, the most recent snapshot.
