Logbeam 0.7.0

Added

• New errors in Compare. Compare two runs of a CI job, and above the diff Logbeam lists the errors
  that are new in the second one, with how often they happened; the ones that are gone are listed apart.
  Errors are matched by message and first stack frames, with times, numbers and IDs ignored. Click one
  to jump to it in the diff (#13).

Improved

• Jenkins consoles. Logs without timestamps no longer carry the last level on to every line after
  it: [Pipeline] steps and the + command lines Jenkins echoes start entries of their own, and a bare
  java.lang.…Exception: line is an error.
• IDs in hex. Short commit SHAs and cache keys (41aa0be, node-modules-9f2c71d) are ignored by
  "Ignore timestamps, IDs and durations" in Compare, and by error groups and collapsed repeats.
