v0.21.0-rc1

Added

Changed

• 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.

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.

v0.20.9-rc0

Fixed

• Do not crash on prometheus export that includes blank lines.

v0.20.8

Added

• Parse working set memory from cgroups on Linux, opens the door to future
