v0.6.0

Release Notes

This release adds an in-memory client for tests and support for servers that only speak RESP2.

• In-memory client for tests. sage-testkit provides InMemorySageClient, a SageClient that needs no Redis server, for every backend. Code that takes a SageClient can be tested with it unchanged. See Testing.

  def visit(client: SageClient, page: String) = client.incr(s"visits:$page")
  
  test("counts visits") {
    val client = InMemorySageClient()
    for {
      _     <- visit(client, "home")
      count <- visit(client, "home")
    } yield assertTrue(count == 2L)
  }

• RESP2 fallback. When a server rejects HELLO 3, Sage now continues with RESP2, so it can connect to Redis before 6.0 and to RESP2-only proxies. The new SageConfig.protocol setting controls this. See Protocol version.

• Bug fixes. On Valkey, JSON length and key queries on a missing key no longer fail to decode. The direct backend no longer risks a stack overflow in some recursive loops.

• Binary compatibility. The new SageConfig field breaks binary compatibility with 0.5.0. Source compatibility is kept.
