# What's new

This release contains new features, performance improvements and important bug fixes.

# New Features

Indexing of nested object fields: feature must be enabled via the enable_nested_fields option during collection creation.
Cross-field OR and complex filter expressions: a filter query like is_premium: true || (price:> 100 && category: shoes) is now possible.
Vector search: support for both exact & HNSW-based approximate vector searching.
Multi-lingual support: Chinese, Japanese, Korean, Cyrillic and Thai are now supported via the use of field-level locale flag in the collection schema.
Optional filtering: sort_by clause can now accept an expression whose result is used for sorting, e.g. sort_by=_eval(brand:nike):desc,_text_match:desc.
Preset search configurations: manage your search query parameters by storing them within Typesense as a "preset", that you can refer to during query time. This helps in keeping the query parameters hidden away from public view.

# Enhancements

New text_match_type parameter that allows you to customize how multi-field text relevancy score is computed.
Improve performance of large collection deletions.
Ability to clone a collection schema (without documents), overrides and synonyms.
New highlight structure that mimics the original document structure. Nested fields are highlighted only in this new structure, which is returned in a key named highlight in the JSON response.
Allow override rules to be processed past the first match via the stop_processing flag (default is true).
Support locale and symbols in synonyms via the locale and symbols_to_index options during synonym creation.
Allow cloning of collection schema & linked assets (like synonyms, overrides) from a reference collection.
Support query replacement action in an override via the replace_query option.
Support an override to be active with a given time window via the effective_from_ts and effective_to_ts options.
Support filter_by rule in overrides.
New --skip-writes flag for starting Typesense in a mode that does not read writes from the Raft log. This is useful when the server has crashed due to some recent bad writes that you want to skip over temporarily.
New --memory-used-max-percentage and --disk-used-max-percentage flags for preventing writes when a specified memory/disk threshold is breached.
Allow the imported documents and their ids to be returned in the import response via the return_doc and return_id options.
API for compacting the on-disk database via the POST /operations/db/compact end-point.

# Bug Fixes

Fixed some edge cases with schema alteration.
Fixed a race condition in parallel collection creation that manifested on localhost, especially on Mac.
Fixed an edge case in highlighting involving non-ASCII unicode characters.
Fixed sort by string not accounting for accented characters.
Fixed an edge case in numerical facet field values not being fully removed on deletion.
Fixed HTTPS POST body buffering removing genuine trailing white space in the chunked payload in some cases.
Fixed float field validation to handle scientific notation.
Fixed a bug involving exact filter match on array.
Fixed a few edge cases that showed up in super-large documents that contained greater than 64,000 tokens.
Implemented automatic log rotation for RocksDB info logs. Previously, one had to restart the server for truncation or perform external truncation via logrotate.

# Deprecations / behavior changes

The default value for search_cutoff_ms is now 30000, i.e. 30 seconds. If you wish to allow searches to run longer than that, you can pass a higher value as a search parameter.
Disable text match score bucketing, if there are more buckets than the number of results found. Previously, results were being aggregated into a single score.
The older highlights key in the response is deprecated (but is still returned for now). Use the new highlight object in the response for highlighting information.
The text_match key in the response is deprecated (but is still returned for now) in favor of the new text_match_info object that returns fine grain matching information, including the score.

# Upgrading

Before upgrading your existing Typesense cluster to v0.24.0, please review the behavior changes above to prepare your application for the upgrade.

We'd recommend testing on your development / staging environments before upgrading.

# Typesense Cloud

If you're on Typesense Cloud:

Go to https://cloud.typesense.org/clusters (opens new window).
Click on your cluster
Click on "Cluster Configuration" on the left-side pane, and then click on "Modify"
Schedule a time for the upgrade.

# Self Hosted

If you're self-hosting Typesense, here's how to upgrade:

# Single node deployment

Trigger a snapshot to create a backup of your data.
Stop Typesense server.
Replace the binary via the tar package or via the DEB/RPM installer.
Start Typesense server back again.

# Multi-node deployment

To upgrade a multi-node cluster, we will be proceeding node by node to ensure the cluster remains healthy during the rolling upgrade.

NOTE: During the upgrade, we have to ensure that the leader of the cluster is using the older Typesense version. So we will upgrade the leader last. You can determine whether a node is a leader or follower by the value of the state field in the /debug end-point response.

State	Role
1	LEADER
4	FOLLOWER

Trigger a snapshot to create a backup of your data on the leader node.
On any follower, stop Typesense and replace the binary via the tar package or via the DEB/RPM installer.
Start Typesense server back again and wait for node to rejoin the cluster as a follower and catch-up (/health should return healthy).
Repeat steps 2 and 3 for the other followers, leaving the leader node alone for now.
Once all the followers have been upgraded to v0.24.0, stop Typesense on the leader.
The other nodes will elect a new leader and keep working.
Replace the binary on the old leader and start the Typesense server back again.
This node will re-join the cluster as a follower, and we are done.
