AI Summary

This release focuses on safety and performance improvements for TigerBeetle, including the reversion of unique keys to fix compatibility issues and the introduction of online schema validation. It also includes updates to client libraries across multiple languages and adds an experimental CLI feature for memory management.

Key Highlights

Reverted unique keys to resolve compatibility issues caused in a previous release.
Introduced online schema validation to ensure coherent `key_min`/`key_max` when reading data.
Applied micro-optimizations to the radix sort algorithm to avoid copies with large stack-allocated values.
Added an experimental `--memory` flag to the CLI for automatic grid and object cache sizing.
Enhanced Ruby and Rust client libraries with improved bounds checking and overflow checks.

New Features

Extended `inspect constants` to catch schema changes and print the `Checkpoint Schedule`.
Implemented online schema validation.
Added experimental CLI `--memory` flag.
Added u128 bounds check in the Ruby client.
Improved the Rust client by removing the bitflags dependency and enabling overflow checks.

# 0.17.9

### Supported upgrade versions

Oldest supported client version: 0.16.4
Oldest upgradable replica version: 0.17.5

## Server

* Binary: Download the zip for your OS and architecture from this page and unzip.
* Docker: `docker pull ghcr.io/tigerbeetle/tigerbeetle:0.17.9`
* Docker (debug image): `docker pull ghcr.io/tigerbeetle/tigerbeetle:0.17.9-debug`

## Clients

**NOTE**: Because of package manager caching, it may take a few
minutes after the release for this version to appear in the package
manager.

You cannot run a newer client against an older cluster: clients are only compatible
with replicas from their own release *or newer*, subject to the newer release's
`Oldest supported client version`.

* .NET: `dotnet add package tigerbeetle --version 0.17.9`
* Go: `go mod edit -require github.com/tigerbeetle/tigerbeetle-go@v0.17.9`
* Java: Update the version of `com.tigerbeetle.tigerbeetle-java` in `pom.xml`
  to `0.17.9`.
* Node.js: `npm install --save-exact tigerbeetle-node@0.17.9`
* Python: `pip install tigerbeetle==0.17.9`
