CHANGELOG.markdown

Pending

6.2.0

• Fix compatibility with http >= 6.0.0 (#613)

6.1.1

• Fix Redis 5 prepend interaction (#611)

6.1.0

• Ruby 4 support
• Update gem metadata
• Add backtrace_additional_directories config option to allow additional directories to be included in the backtrace parser

6.0.2

• Fix endpoint_sample_rate and job_sample_rate to support float values

6.0.0

Breaking Change Sampling configuration options now take float arguments between 0.0 and 1.0. This means you can now set sample rates lower than one. Backwards compatibility is maintained for existing config > 1 by converting to a percentage internally. If your endpoint is sampled at exactly 1%, you must now set 0.01 instead of 1.

• Fix a memory leak in error recovery code
• Fix a minor race condition in data coordination between processes.

  • An SQL sanitation performance improvement (strip! vs. gsub!)
  • Removing the TRAILING_SPACES regex - not used across all db engines and adds a bit more overhead
