Changelog

Safety And Performance

• #2394,
  #2401

  TigerBeetle clients internally batch operations for improved performance. Fix a bug where an
  unclosed link chain could be batched before another linked chain, causing them to be treated as
  one long linked chain. Additionally, prevent non-batchable requests from sharing packets entirely.

• #2398

  AMOUNT_MAX is used as a sentinel value for things like balancing transfers to specify moving
  as much as possible. Correct and fix its value in the Java client. Thanks @tKe!

Features

• #2274

  Improve the benchmark by adding Zipfian distributed random numbers, to better simulate realistic
  conditions and as a precursor to approximating YCSB.

• #2393

  Previously, TigerBeetle's clients disallowed empty batches locally, before the request was even
  sent to the cluster. However, this is actually a valid protocol message - even if it's not used by
  the current state machine - so allow empty batches to be sent from clients.

• #2384

  Revamp client documentation so that each snippet is self-contained, and standardize it across all
  languages.

Internals

• #2404

  Give the DevHub a fresh coat of paint, and fix
  passing seeds being blue in dark mode.

• #2408,
  #2400,
  #2391,
  #2399,
  #2402,
  #2385

  Improve VOPR logging and fix a few failing seeds.
