+# Release Announcement v1.3.0
+We are pleased to announce that the Apache YuniKorn community has voted to
+release 1.3.0. Apache YuniKorn is a standalone resource scheduler, designed
+for managing and scheduling Big Data workloads on container orchestration
+frameworks like Kubernetes for on-prem and on-cloud use cases.
+
+## Overview
+The Apache YuniKorn community has resolved 160
+[JIRAs](https://issues.apache.org/jira/issues/?filter=12352568)
+in this release.
+
+Release manager: Yu Teng Chen
+
+Release date: 2023-06-09
+
+## Highlights
+
+### Kubernetes version support
+YuniKorn 1.3.0 supports running on Kubernetes clusters from version 1.21
+through 1.26. Support for running on Kubernetes 1.27 is **not** supported,
+but is planned for YuniKorn 1.4.0.
+
+**NOTE**: YuniKorn 1.3.0 is the last release planned which will support
+Kubernetes 1.21 through 1.23; YuniKorn 1.4.0 is expected to require Kubernetes
+1.24 or later.
+
+Please see [YUNIKORN-1699](https://issues.apache.org/jira/browse/YUNIKORN-1699)
+for details.
+
+### Preemption support
+YuniKorn now has comprehensive support for preemption, including customizable
+policies per queue. Please see the the Preemption
+[design documentation](https://yunikorn.apache.org/docs/next/design/preemption)
+for more details.
+
+JIRA: [YUNIKORN-1461](https://issues.apache.org/jira/browse/YUNIKORN-1461)
+
+### Better support for BestEffort pods
+YuniKorn now tracks the number of pods scheduled as part of queue quota limits.
+This allows limiting parallelism within a queue, but also provides better
+support for running Kubernetes pods with the `PodQOSBestEffort` scheduling
class
+(i.e. those with no explicit resources requested).
+
+Please see [YUNIKORN-1632](https://issues.apache.org/jira/browse/YUNIKORN-1632)
+for details.
+
+### Lighter and more secure images
+YuniKorn 1.3.0 has moved to using scratch base images for all containers. This
+results in a smaller footprint as well as improved security as YuniKorn no
+longer ships any third-party software in our container images.
+
+A prerequisite for using scratch images was the move from nginx to a go-based
+web server for the web application. Please see
+[YUNIKORN-1672](https://issues.apache.org/jira/browse/YUNIKORN-1672) and
+[YUNIKORN-1535](https://issues.apache.org/jira/browse/YUNIKORN-1535) for
+details.
+
+### Dynamic namespace support in admission controller
+The YuniKorn admission controller now suports per-namespace annotations to
+control YuniKorn-specific processing. Previously, only a static list of
+regular expressions (still supported) could be used to select namespaces.
+
+Please see [YUNIKORN-1647](https://issues.apache.org/jira/browse/YUNIKORN-1647)
+for details.
+
+### CPU and memory optimization
+YuniKorn 1.3.0 contains several optimizations for CPU and memory usage, making
+this release the lightest and fastest yet. Some examples:
+
+* [YUNIKORN-1719](https://issues.apache.org/jira/browse/YUNIKORN-1719)
+ Improve the performance of Application.sortRequests()
+* [YUNIKORN-1720](https://issues.apache.org/jira/browse/YUNIKORN-1720)
+ Improve the performance of node.preAllocateCheck()
+* [YUNIKORN-1722](https://issues.apache.org/jira/browse/YUNIKORN-1722)
+ Excessive resource clone calls in calculateNodesResourceUsage()
+* [YUNIKORN-1746](https://issues.apache.org/jira/browse/YUNIKORN-1746)
+ Improve the performance of nodeInfoListerImpl.List()
+
+## Community
+The Apache YuniKorn community is pleased to welcome new PMC member
