  • Passing fractional timestamps to span start/finish are now properly handled.
  • Several bugs were fixed with the proto transport option around span duration and span ids.
  • We now support a custom logger function (thanks @Rowno), see README for more details.

0.21.0

  • Update thrift to 0.11.0. This breaks support for node.js versions <= 5.8.

0.20.14

  • Add new option to Tracer: disable_clock_skew_correction bool optional, defaults to 'false', which disables client-side clock kew correction.

0.20.13

0.20.0

  • API CHANGE: use new lightstep.Tracer(opts) to return a lightstep Tracer instance
  • API CHANGE: lightstep-browser.min.js and lightstep-browser.js use a lightstep rather than LightStep prefix for LightStep symbols
  • API CHANGE: two new length limits for key-value logs: log_field_key_hard_limit and log_field_value_hard_limit, both specified as a number of bytes
  • Many implementation changes, especially support for key-value logging per OpenTracing-javascript 0.13.*

0.11.17

  • Update the internal, automatic tracer tags to follow the convention of using a lightstep.* prefix

0.11.16

  • Option verbosity=1 will now throttle the error logging to the first error per minute
  • Option delay_initial_report_millis will delay the initial report to the collector by at least some value between 0 and this value. This is useful when spawning a large number of new processes to help distribute the load at startup. Note: this is a non-standard option that is not supported by other LightStep libraries and is subject to change.
  • Back off on errors is more now more aggressive. The back off always uses the the reporting interval, not the clock calibration interval.

0.11.2

  • Fixes defects where the XHR instrumentation was still using the old parent option
  • Add documentation for the non-standard option disable_reporting_loop

    • 1: echo only the first error to the host application's console
    • > 1: echo internal errors, warnings, and info statements to the host application's console. Higher values will yield more detailed logs

  • Internal errors, warnings, and info logs will no longer show up in the collected traces
  • Option log_to_console will no longer echo internal errors, warnings, and info logs
