4.3.5 Deprecations and breaking changes

Micrometer Metrics

numThreads is deprecated in InfluxDB options

• https://github.com/vert-x3/vertx-micrometer-metrics/issues/141

As part of another change (introducing InfluxDB V2 options), the numThreads property has been deprecated.

Indeed, it's no longer used by Micrometer and will eventually be removed.

Ignite Cluster Manager

cacheMode LOCAL is no longer supported in Ignite options as it got removed from Apache Ignite in version 2.14.0

• https://github.com/apache/ignite/commit/01a7d075a5f48016511f6a754538201f12aff4f7

If you are not using any custom configuration or a custom Ignite instance you should not be impacted by this change.

Zookeeper Cluster Manager

Upgrade log4j and slf4j dependencies

• https://github.com/vert-x3/vertx-zookeeper/pull/130

This PR aligns logging dependencies versions with those of Vert.x core. Besides, Vert.x Zookeeper now depends on log4j2 instead of log4j, which is no longer maintained.
