v2.6.2

Recommended Upgrade

This is a minor update, that primarily focuses on fixing nodes that result in crashes due a segfault in SPV under certain specific conditions, when it's turned on. Contains a few other minor additional fixes and features.

Upgrade Notes

• For nodes that are running >= v2.6.1, this is a drop in upgrade. No reindex or fresh sync needed.
• 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.
