Today we're announcing the release of Zcash 1.0.9. This is our first release using our new release cycle and focused exclusively on improvements to testing, security, benchmarking, automation, and portability.
|
|
|
|
This release is our first with the auto-deprecation feature described in our <a class="reference external" href="/release-cycle-and-lifetimes/">Release Cycles and Lifetimes</a> post. It also introduces opt-in support for the <a class="reference external" href="https://www.amqp.org/">AMQP protocol</a>.
|
|
|
|
We encourage all users and miners to update to this new version. See our <a class="reference external" href="https://z.cash/download.html">download</a> page and the <a class="reference external" href="https://github.com/zcash/zcash/wiki/1.0-User-Guide">1.0 User Guide</a> for more information.

</ol>
|
|
In addition to improvements to the Zcash codebase itself, we made substantial improvements to our continuous integration (CI) system: we upgraded the Buildbot framework, modularized the CI code for easier maintenance, introduced a 'supported vs unsupported' build worker framework, repaired coverage analysis, and added new benchmarks.
|
|
|
|
These changes allow us to begin adding support for more platforms, to begin adding more benchmarks for judiciously selected optimization work, and to further improve the CI system with minimal disruption to future reference client releases.
