== Upgrading from 6.4 and earlier

=== Potential breaking changes

==== Updates to bundled Gradle dependencies

- Kotlin has been updated to https://github.com/JetBrains/kotlin/releases/tag/v1.3.72[Kotlin 1.3.72].
- Groovy has been updated to https://groovy-lang.org/changelogs/changelog-2.5.11.html[Groovy 2.5.11].

==== Updates to default tool integration versions

      Note that while this release changes the *protocol* to be incremental, Istio does not yet send perfect minimal incremental updates.
      However, there are already optimizations in place for a variety of critical code paths, and this change enables us to continue optimizations.
      

	// back quota evaluations that touch the same quota doc.  This only works because we can compare etcd resourceVersions
	// for the same resource as integers.  Before this change: 22 updates with 12 conflicts.  after this change: 15 updates with 0 conflicts
	updatedQuotas *lru.Cache
}

// newQuotaAccessor creates an object that conforms to the QuotaAccessor interface to be used to retrieve quota objects.
