Meilisearch v0.26.0 — Release Notes & Engineering Impact

For more information on how to update to the latest version of Meilisearch, read our [dedicated guide](https://docs.meilisearch.com/create/how_to/updating.html#update-to-the-latest-meilisearch-version). ## New features ### Tenant tokens We released one of the features most requested by our users: tenant tokens. (https://github.com/meilisearch/meilisearch/pull/2096) @ManyTheFish Tenant tokens allow developers to restrict access to documents depending on the end-user making the search request, effectively enabling multi-tenant indexes. A tenant token is a [JWT](https://jwt.io/). It must be generated by combining an API key with a set of permissions and rules the developer wishes to apply to an end user's search. For more information on tenant tokens, read our [dedicated guide](https://docs.meilisearch.com/learn/security/tenant_tokens.html#multitenancy-and-tenant-tokens). ### Auto-batching (experimental) This version includes the auto-batching feature. (https://github.com/meilisearch/meilisearch/pull/2005) @MarinPostma Auto-batching improves indexing speed by batching together consecutive document additions. Here is a simple way to use it: ```bash meilisearch --enable-auto-batching ``` This is an experimental feature. Based on user feedback, it might be completely reworked or outright removed in a future release. You can read more about how to use auto-batching in [this discussion](https://github.com/meilisearch/meilisearch/discussions/2070). ## Breaking changes - New dump behavior (https://github.com/meilisearch/meilisearch/pull/2098) @irevoire Importing a dump into an instance with an existing database using `--import-dump` will throw an error on the CLI. Similar to snapshots, the `--ignore-dump-if-db-exists` and `--ignore-missing-dump` flags have been added for dumps. - New flag behavior for the CLI (https://github.com/meilisearch/meilisearch/pull/2068) @MarinPostma Affected options: `--no-analytics`, `--schedule-snapshot`, `--ignore-missing-snapshot`, `--ignore-snapshot-if-db-exists`, `--ssl-require-auth`, `--ssl-resumption`, `--ssl-tickets` ❌: `meilisearch --no-analytics=true` ✅: `meilisearch --no-analytics` - Remove armv8 binary from the release assets.
