# What's new

This release fixes some important bugs identified in the recently released v0.25.0.

The changelog below contains aggregates all the changes between v0.24.1 and v0.25.x.

# New Features

# Enhancements

  • Resolve field names using wildcard: fields can now be resolved in facet_by, query_by, include_fields, exclude_fields, highlight_fields and highlight_full_fields when a wildcard expression is used, e.g. title_* will match title_en.
  • Ability to sort grouped hits based on the size of each group, using sort_by: _group_count:desc.
  • A count is returned for total number of records under each group even if the hits are truncating via group_limit.
  • The != filtering operation can now be performed against numerical fields. Previously only string fields were supported for this operator.
  • Support use of preset parameter in embedded API key.
  • Support nested dynamic fields.
  • Migrated build system to Bazel.
  • New server configuration option (--reset-peers-on-error) that makes the cluster forcefully refresh its peers when an unrecoverable clustering error happens due to sudden change of peer IPs. There's also an equivalent /operations/reset_peers API. Be careful while using this option, as it can lead to transient loss of data.

# Bug Fixes

  • Fixed updates of nested object field values.
  • Fix geopoint indexing in nested fields.
  • Fixed some special characters not getting highlighted properly in prefix searches.
  • Fixed a bug in phrase matches on array.
  • Fixed a socket leak on followers of a cluster when import data fails validation.
  • Fixed high memory usage incurred in export/import of large datasets.
  • Fixed bad unicode characters in export.
  • Fixed errors that were caused by presence of bad Japanese unicode characters in import.
  • Fixed broken http/2 support on CURL v8.
  • Fixed non-curated members of a group appearing in curated override results.
  • Fixed override query rule being case-sensitive.
  • Fixed phrase search not considering field weights.
  • [New in v0.25.1] Handle mismatched vector dimensions during indexing
  • [New in v0.25.1] Allow remote embedders to use multiple per-collection credentials
  • [New in v0.25.1] Fixed altering of schema involving embedding fields
  • [New in v0.25.1] Fixed charset in content-type header of export API response
  • [New in v0.25.1] Fixed an issue in analytics query aggregation that caused crash on empty collections
  • [New in v0.25.1] Fixed group by on vector search
  • [New in v0.25.1] Improved error handling of remote embedding APIs
  • [New in v0.25.1] Fixed tokenizer of embedding models that use XLM-RoBERTa
  • [New in v0.25.1] Fixed upsert of unchanged docs containing embedding fields, that would cause the embedding field value to be removed.
  • [New in v0.25.1] Fixed text match score calculation to consider the presence of dropped tokens when ranking.

# Deprecations / behavior changes

There are no depreciation or behavior changes in this version.

# Upgrading

Before upgrading your existing Typesense cluster to v0.25.1, 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:

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

# Self Hosted

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

# Single node deployment

  1. Trigger a snapshot to create a backup of your data.
  2. Stop Typesense server.
  3. Replace the binary via the tar package or via the DEB/RPM installer.
  4. 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. Trigger a snapshot to create a backup of your data on the leader node.
  2. On any follower, stop Typesense and replace the binary via the tar package or via the DEB/RPM installer.
  3. Start Typesense server back again and wait for node to rejoin the cluster as a follower and catch-up (/health should return healthy).
  4. Repeat steps 2 and 3 for the other followers, leaving the leader node uninterrupted for now.
  5. Once all followers have been upgraded to v0.25.1, stop Typesense on the leader.
  6. The other nodes will elect a new leader and keep working.
  7. Replace the binary on the old leader and start the Typesense server back again.
  8. This node will re-join the cluster as a follower, and we are done.

# Downgrading

Once you upgrade to v0.25 of Typesense Server the internal structure of the data directory becomes incompatible with older versions of Typesense.

However, if you need to downgrade to v0.24, we've released a special version v0.24.2 that backports these data structure changes back to 0.24 while keeping other 0.24.1 features as is.

So v0.25 can only be downgraded to v0.24.2.
