Notable changes
Feature Deprecation and removal
zcashd
now has a process
for how features of the public API may be deprecated and removed. Feature
deprecation follows a series of steps whereby, over a series of releases,
features first remain enabled by default (but may be explicitly disabled), then
switch to being disabled by default, and eventually are removed entirely.
A new string-valued option, -allowdeprecated
has been introduced to allow a
user to explicitly manage the availability of deprecated zcashd
features. This
flag makes it possible for users to reenable deprecated methods and features
api that are currently disabled by default, or alternately to explicitly
disable all deprecated features if they so choose. Multiple instances of this
argument may be provided. A user may disable deprecated features entirely
by providing the string none
as the argument to this parameter. In the case
that none
is specified, multiple invocations of -allowdeprecated
are not
permitted.
Deprecated
As of this release, the following features are deprecated, but remain
available by default. These features may be disabled by setting
-allowdeprecated=none
. After release 5.3.0, these features will be
disabled by default and the following flags to -allowdeprecated
will
be required to permit their continued use:
legacy_privacy
- the default "legacy" privacy policy for z_sendmany is deprecated. When disabled, the default behavior of z_sendmany will conform to theFullPrivacy
directive (introduced in 4.7.0) in all cases instead of just for transactions involving unified addresses.getnewaddress
- controls availability of thegetnewaddress
RPC method.z_getnewaddress
- controls availability of thez_getnewaddress
RPC method.addrtype
- controls availability of the deprecatedtype
attribute returned by RPC methods that return address metadata.
As of this release, the following previously deprecated features are disabled
by default, but may be be reenabled using -allowdeprecated=<feature>
.
- The
zcrawreceive
RPC method is disabled. It may be reenabled withallowdeprecated=zcrawreceive
- The
zcrawjoinsplit
RPC method is disabled. It may be reenabled withallowdeprecated=zcrawjoinsplit
- The
zcrawkeygen
RPC method is disabled. It may be reenabled withallowdeprecated=zcrawkeygen
Option handling
- The
-reindex
and-reindex-chainstate
options now imply-rescan
(provided that the wallet is enabled and pruning is disabled, and unless-rescan=0
is specified explicitly).
RPC Changes
- The deprecated
zcrawkeygen
,zcrawreceive
, andzcrawjoinsplit
RPC methods are now disabled by default. Use-allowdeprecated=<feature>
to select individual features if you wish to continue using these APIs.
Build system
zcutil/build.sh
now automatically runszcutil/clean.sh
to remove files created by previous builds. We previously recommended to do this manually.
Dependencies
- The
boost
andnative_b2
dependencies have been updated to version 1.79.0
