|
Important Updates
|
|
-----------------
|
|
|
|
Several important updates have been added to Dogecoin Core, including fixes
|
|
backported from Bitcoin Core's upstream.
|
|
|
|
### Reduce Peer INV Object Counts
|
|
|
|
Previously, Dogecoin Core nodes would maintain a large list of inventory for
|
|
each peer. This is excessive and unnecessary and has been reduced to a more
|
|
reasonable number.
|
|
|
|
*Implemented with #3577*
|
|
|
|
### Improve Transaction Request Tracking
|
|
|
|
A new transaction request tracking system improves the way Dogecoin Core
|
|
communicates with other peers. Notably, this improvement prioritizes
|
|
communication with outbound peers over inbound peers and makes CPU and memory
|
|
use more reliable and scalable with the number of peers.
|
|
|
|
*Implemented with #3577*
|
|
|
|
### Improve Orphan Transaction Handling
|
|
|
|
In previous versions of Dogecoin Core, orphan transactions were processed in a
|
|
complex fashion. Now they are processed more like regular getdata messages,
|
|
which allows for more efficient handling of messages arriving from other peers,
|
|
as well as other code simplifications.
|
|
|
|
*Implemented with #3575*
|
|
|
|
### Reduce Getheaders Traffic for INV Messages
|
|
|
|
Dogecoin Core now sends a getheaders message for one block when announced in an
|
|
INV message, and it sends only a single such message rather than multiple per
|
|
INV message. This reduces traffic and simplifies the logic of the code.
|
|
|
|
*Implemented with #3568*
|
|
|
|
### Improve Reporting of Difficulty Adjustment Errors
|
|
|
|
Previously, difficulty adjustment violations were not reported for chains that
|
|
branched off before the last checkpoint. This has been changed by moving the
|
|
checkpoint check after the difficulty check.
|
|
|
|
*Implemented with #3576*
|
|
|
|
### Security Policy Documented
|
|
|
|
The [SECURITY.md](SECURITY.md) file describes how to report a potential
|
|
vulnerability or security issue in Dogecoin Core.
|
|
|
|
*Implemented with #3611*
|
|
|
|
|
|
Dependency Updates
|
|
------------------
|
|
|
|
* Updated fontconfig to version 2.12.6 (#3590)
|
|
* Updated freetype to version 2.11.0 (#3590)
|
|
* Updated expat to version 2.6.2 (#3590)
|
|
* Allow compiling with Boost 1.80 and newer (#3588)
|
|
|
|
|
|
Minor Changes
|
|
=============
|
|
|
|
* Dogecoin Core now supports compilation with C++14 and C++17, if you select
|
|
the appropriate configuration flags (#3494, ... )
|
|
* With the C++ version updates, the code now uses more built-in C++ features instead
|
|
of Boost equivalents, where possible (various commits)
|
|
* The CI configuration was updated to be compatible with newer versions of Python (#3582)
|
|
* Rely on the well-tested OpenSSL secure random functions, but allow the use of std::shuffle (#3521)
