Weaviate 1.18 is here

Hello Weaviate friends, πŸ€—We have exciting news: Weaviate v1.18 is LIVE!!!So, let's get right into it.

Weaviate 1.18

The engineering team and the community worked hard to deliver the best and most exciting Weaviate version yet. In v1.18 you can look forward to:

  1. Faster Filtering with Roaring Bitmaps – a huge speed boost for queries combining scalar filter (where) with vector search (i.e. nearText, hybrid).

  2. HNSW-PQ – enables great performance at a fraction of the previous RAM requirements.

  3. Improvements to BM25 and Hybrid Search – faster scoring with the WAND implementation and added filter support.

  4. Replication – two new replication features: tunable consistency for all read and write REST operations, and repair on read.

  5. Cursor API – simple way to export every object from Weaviate.

  6. Azure Storage backup module – extends our cloud-native backup capabilities further by introducing the backup-azure module.

You can read all about it in the Weaviate 1-18 release blog post.

Many contributors

Looking at the release notes, it took 18 different contributors to make this release happen.

With seven new contributors (internal and external) joining the proud ranks of people who can call themselves "Weaviate creators". 😊

It is great to see contributions from the Go community. I want to give a big shout to Oleksandr Redko – for the PR to "Add missing calls to file.Close()" – and Eng Zer Jun – for the PR to "use t.Setenv to set env vars".

Updated styling for blogs, docs and podcasts

We've updated the style for our blogs, docs and podcasts. To make all the essential content more readable and findable. What do you think? Pretty neat... right?

A cool trick - "night and day"

Did you know you can change the website between dark and light modes?If you don't do anything, the website will change to the mode indicated by your operating system.

This even works for some of the pictures. Try changing the theme while you read the latest blog. This may not change your life just yet, but it is pretty to look at. πŸ˜‰
