   I also think the further improvements on filter pushdown could be highlighted in the blog:

   • perf: Push down join key filters for LEFT/RIGHT/ANTI joins #19918
   • feat: Pushdown filters through UnionExec nodes #20145
   • Support parent dynamic filters for more join types #20192
   • Extend dynamic filter to joins that preserve probe side ON #20447 (if merged until then)

   I also think the further improvements on filter pushdown could be highlighted in the blog:

   * [perf: Push down join key filters for LEFT/RIGHT/ANTI joins #19918](https://github.com/apache/datafusion/pull/19918)
   
   * [feat: Pushdown filters through `UnionExec` nodes #20145](https://github.com/apache/datafusion/pull/20145)
   
   * [Support parent dynamic filters for more join types #20192](https://github.com/apache/datafusion/pull/20192)
   
   * [Extend dynamic filter to joins that preserve probe side ON #20447](https://github.com/apache/datafusion/pull/20447) (if merged until then)
   

   Note for when the blog is created: #20447 was merged already but won't be included in the 53 release.
