v0.13.0-beta.0: HNSW indexing; Configurable Summarizer Prompt

What's Changed

• feat: HNSW indexing; refactor doc embeddings by @danielchalef in #209
• feat: Configurable Summarizer Prompt by @bricemacias in #211
• feat: darkmode toggle by @danielchalef in #210

HNSW index support

Requires pgvector v0.5 or later to be installed in order to create HNSW indexes.

• Message and Document embedding columns default to using an HNSW index
• Manual Collection indexing is a noop if this is the case

Also includes:

• A refactoring of Collection embedding functionality

Installation or Upgrading

Ensure that your Postgres provider has pgvector 0.5 installed -or- that you're using the latest Zep Postgres container.

Modify the docker-compose.yaml file (or your Render or other hosting config) to include the correct Zep container build tags:

  zep:
    image: ghcr.io/getzep/zep:0.13.0-beta.0

-or for cloud deployments-

  zep:
    image: ghcr.io/getzep/zep-cloud:0.13.0-beta.0

and then run a pull -or- run a redeploy in your cloud environment.

docker compose pull

Your Zep log file should contain an INFO level entry as follows:

vector extension version is >= 0.5.0. hnsw indexing available

IMPORTANT: Pre-release software. May contain bugs!

This is an early release and may container bugs! Please back up your database prior to upgrading.
