Release notes

What's new

• Compute: Released a new pg_tiktoken PostgreSQL extension, created by the Neon engineering team. The extension is a wrapper for OpenAI’s tokenizer. It provides fast and efficient tokenization of data stored in a PostgreSQL database. The extension supports two functions:

  • The tiktoken_encode function takes text input and returns tokenized output, making it easier to analyze and process text data.
  • The tiktoken_count function returns the number of tokens in a text, which is useful for checking text length limits, such as those imposed by OpenAI’s language models.

  For more information about the pg_tiktoken extension, refer to the blog post: Announcing pg_tiktoken: A Postgres Extension for Fast BPE Tokenization. The pg_tiktoken code is available on GitHub.

• Compute: Added support for the PostgreSQL prefix, hll and plpgsql_check extensions. For more information about PostgreSQL extensions supported by Neon, see PostgreSQL extensions.

• Compute, Pageserver, Safekeeper: Added support for RS384 and RS512 JWT tokens, used to securely transmit information as JSON objects.

• Pageserver: Removed the block cursor cache, which provided little performance benefit and would hold page references that caused deadlocks.

• Autoscaling: Added support for scaling Neon's local file cache size when scaling a virtual machine.
