- **Automatic indexes compaction** ([#478](https://github.com/manticoresoftware/manticoresearch/issues/478)). Finally you don't have to call OPTIMIZE manually or via a crontask or other kind of automation. Manticore now does it on your own. You can set default compaction threshold via [optimize_cutoff](../Server_settings/Searchd.md#optimize_cutoff).
- **Automatic indexes compaction** ([#478](https://github.com/manticoresoftware/manticoresearch/issues/478)). Finally you don't have to call OPTIMIZE manually or via a crontask or other kind of automation. Manticore now does it on your own. You can set default compaction threshold via [optimize_cutoff](../Server_settings/Setting_variables_online.md) global variable.
- **Chunk snapshots and locks system revamp**. These changes may be invisible from outside at first glance, but they improve the behaviour of many things happening in real-time indexes significantly. In a nutshell, previously most Manticore data manipulation operations relied on locks heavily, now we use disk chunk snapshots instead.

### optimize_cutoff

<!-- example conf optimize_cutoff -->
Sets default index compaction threshold. Read more here - [Number of optimized disk chunks](../Securing_and_compacting_an_index/Compacting_an_index.md#Number-of-optimized-disk-chunks). Can be overridden with per-query option [cutoff](../Securing_and_compacting_an_index/Compacting_an_index.md#Number-of-optimized-disk-chunks). Can be changed dynamically via [SET GLOBAL](../Server_settings/Setting_variables_online.md#SET).
