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.
