Meilisearch v1.45.1 Reverts Autobatch Deletions by Filter

Meilisearch just dropped v1.45.1, and it’s a patch that walks back a notable change. The team has reverted the autobatch deletions by filter with additions feature that shipped in v1.45.0. If you update, your search engine will behave more predictably again. Let’s dig into what actually changed and why this reversal matters.

What Changed

In v1.45.0, Meilisearch introduced a new way to batch deletions and additions together. The idea was efficiency: when you delete documents by filter and then add new ones in the same batch, the engine would process them together. But this feature hit a snag. The v1.45.1 release simply reverts that change. Specifically, it’s Revert autobatch deletions by filter with additions — a single commit that pulls the feature out.

Why It Matters

So why the sudden reversal? The changelog doesn’t spell it out, but reverting a core batching behavior suggests the feature caused unexpected issues. Maybe it broke document counting, or led to inconsistent search results. For developers relying on predictable batch processing, this is a big deal. It means your deletion-by-filter operations won’t be automatically merged with additions anymore — they’ll run separately as before. If you upgraded to v1.45.0 and noticed odd behavior, this patch should fix it.

Meilisearch moves fast, and this kind of backtracking is rare. But it shows they’re willing to pull a feature if it causes problems. For users, stay on v1.45.1 until the next release.
