# Manticore Search 3.5.4: Python, Java and Javascript clients and faster OPTIMIZE

We are pleased to announce [Manticore Search 3.5.4](https://manticoresearch.com/downloads/) is out, this is our 6th and final release of 2020.

## Faster OPTIMIZE

---

If you use Manticore Search [real-time indexes](https://manual.manticoresearch.com/Read_this_first#Real-time-index-vs-plain-index) you know that there's command [OPTIMIZE INDEX](https://manual.manticoresearch.com/Securing_and_compacting_an_index/Compacting_an_index#OPTIMIZE-INDEX) which does index compaction. Manticore 3.5.4 introduces automatic drop of a disk chunk in a real-time index when [OPTIMIZing](https://manual.manticoresearch.com/Securing_and_compacting_an_index/Compacting_an_index#OPTIMIZE-INDEX) a real-time index when the chunk is obviously not needed any more (all the documents are suppressed). Previously it still required merging, now the chunk can be just dropped instantly. This is useful in case you maintain retention in your index and delete older documents regularly. Now compacting such indexes will be faster.

👷 Work in progress: fully automated index compaction which you won't have to run externally at all!
