@LitecoinZ LitecoinZ released this Jul 15, 2019

LitecoinZ Core version 2.0.2 is now available!

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely
shut down (which might take a few minutes for older versions), then run the
installer (on Windows) or just copy over /Applications/LitecoinZ-Qt (on Mac)
or litecoinz/litecoinz-qt (on Linux).

If your node has a txindex, the txindex db will be migrated the first time you
run 2.0.2 or newer, which may take up to a few hours. Your node will not be
functional until this migration completes.

Compatibility

LitecoinZ Core is extensively tested on multiple operating systems using
the Linux kernel, macOS 10.10+, and Windows 7 and newer (Windows XP is not supported).

LitecoinZ Core should also work on most other Unix-like systems but is not
frequently tested on them.

From 2.0.2 onwards macOS <10.10 is no longer supported. 2.0.2 is built using Qt 5.9.x, which doesn't
support versions of macOS older than 10.10.

Notable changes

Bitcoin 0.12 Performance Improvements

This change makes sigcache faster, more efficient, and larger. It also reduces
the number of database lookups when processing new transactions.

Sprout to Sapling Migration Tool

This release includes the addition of a tool that will enable users to migrate
shielded funds from the Sprout pool to the Sapling pool while minimizing
information leakage.

The migration can be enabled using the RPC z_setmigration or by including
-migration in the litecoinz.conf file. Unless otherwise specified funds will be
migrated to the wallet's default Sapling address; it is also possible to set the
receiving Sapling address using the -migrationdestaddress option in litecoinz.conf.

New consensus rule: Reject blocks that violate turnstile

In this release the consensus rules were changed to enforce a consensus rule
which marks blocks as invalid if they would lead to a turnstile violation in
the Sprout or Shielded value pools.

Developers can use a new experimental feature -developersetpoolsizezero to test
Sprout and Sapling turnstile violations.

64-bit ARMv8 support

Added ARMv8 (AArch64) support. This enables users to build litecoinz on even more
devices.

Fixed a bug in z_mergetoaddress

We fixed a bug which prevented users sending from ANY_SPROUT or ANY_SAPLING
with z_mergetoaddress when a wallet contained both Sprout and Sapling notes.

Insight Explorer

We have been incorporating changes to support the Insight explorer directly from
litecoinzd. v2.0.2 includes the first change to an RPC method. If litecoinzd is
run with the flag --insightexplorer``` (this requires an index rebuild), the RPC method getrawtransaction`` will now return additional information about
spend indices.
