Changes for ZERO 1.0.14

Notable changes

Incoming viewing keys

Support for incoming viewing keys, as described in
the Zcash protocol spec,
has been added to the wallet.

Use the z_exportviewingkey RPC method to obtain the incoming viewing key for a
z-address in a node's wallet. For Sprout z-addresses, these always begin with
"ZiVK" (or "ZiVt" for testnet z-addresses). Use z_importviewingkey to import
these into another node.

A node that possesses an incoming viewing key for a z-address can view all past
transactions received by that address, as well as all future transactions sent
to it, by using z_listreceivedbyaddress. They cannot spend any funds from the
address. This is similar to the behaviour of "watch-only" t-addresses.

z_gettotalbalance now has an additional boolean parameter for including the
balance of "watch-only" addresses (both transparent and shielded), which is set
to false by default. z_getbalance has also been updated to work with
watch-only addresses.

• Caution: for z-addresses, these balances will not be accurate if any
  funds have been sent from the address. This is because incoming viewing keys
  cannot detect spends, and so the "balance" is just the sum of all received
  notes, including ones that have been spent. Some future use-cases for incoming
  viewing keys will include synchronization data to keep their balances accurate
  (e.g. #2542).

Changes for ZERO 1.0.13

This release introduces new features, performance improvements and bug fixes. Our new low memory prover reduces memory usage by 43% when generating a shielded transaction, from 3 GB to 1.7 GB. An experimental feature, payment disclosure, can help services better manage their shielded payments. We also now fully support the z_shieldcoinbase RPC call to help miners sweep up and shield their coinbase rewards.

Summary of the changes included in this release:

Auto-senescence cycle has been reduced from 18 to 16 weeks. (zcash#2733)
Low-memory prover reduces JoinSplit creation memory usage from 3 GB to 1.7GB. (zcash#2670, stats)
Payment disclosure has been added as an experimental feature with new RPC calls z_getpaymentdisclosure and z_validatepaymentdisclosure (zcash#2519). This feature enables a sender to prove that a payment was made to a recipient, which can help services better manage their shielded payments. See the documentation for a full explanation of this new feature.
z_shieldcoinbase is now a fully supported RPC call (zcash#2692). See an explanation of this command here.
Libsnark has been brought into the source repository tree. (zcash#2652)
Fixed potential shutdown errors have been fixed. (zcash#2555)
User interface messages have been cleaned up. (zcash#2548, zcash#2150, zcash#2649)
The extended QA tests have been migrated to Zcash. (zcash#2533)
A workaround has been implemented in the test wallet_protectcoinbase, which was previously failing on some platforms. (zcash#2698)
Benchmarking has been updated with new performance measurements and fixes. (zcash#2645, zcash#2659, zcash#2377, zcash#2687, zcash#2665)
