v0.21.1

Changed

• Added lading version to initial welcome print msg.

Fixed

• Prometheus metric exporter did not include some internal metrics (generator
  metrics)
• Range values in the dogstatsd payload will now generate the full inclusive
  range. Previously, values were generated up to but not including the max
  value.
• HTTP Blackhole now supports ZSTD encoded requests

v0.21.0

Changed

• Improved the block cache construction to better fill the pre-defined space.
• Removed streaming cache method. Fixed is now the only option.
• Users now configure a maximum block size in generators, not individual blocks.
• Maximum datagram size in bytes for unix datagram generator is 8,192.
• Altered default cache construction from 'fixed' to 'streaming'
• Increased maximum DogStatsD context limit from 100k to 1M
• Procfs generator now generates process names as long as 254 characters, up from 253.

Fixed

• The capture manager will no longer panic if recording a capture and checking for a shutdown combined takes longer than one second.
• A shutdown race was partially fixed in the capture manager which could result in truncated (invalid) json capture files.
• Unix datagram generator will not longer 'shear' blocks across datagrams.
• Procfs generator now generates pid/stat files with comm in parens, matching Linux behavior.

Changed

Fixed

v0.20.9

Added

• Enforces changelog entries via CI check
• payloadtool binary useful for developers writing new experiments.
• Respects the env var RUST_LOG to control logging.

Fixed

• During payload generation, blocks will reliably be filled to the requested amount.
• During payload generation, block chunks now give more feedback when the
  requested amount cannot be hit.
• Does not crash on empty line in prometheus exports

Changed

• Increases the amount of blocks available during payload generation.
• DogStatsD tag generation updated to better reflect real DSD traffic.
• Users should avoid setting custom block_sizes and rely on the default
  blocks. payloadtool is available to help evaluate block size options.
