6.1.0.beta (June 11, 2024)

  • [IMPROVEMENT] Initial support for parsing queries from activerecord-sqlserver-adapter

6.0.4 (February 23, 2024)

  • [IMPROVEMENT] Set "turbo-frame" in the request segment when making a Turbo-Frame request

6.0.3 (January 18, 2024)

  • [IMPROVEMENT] Remove an outdated "abbrev" requirement

6.0.2 (January 9, 2024)

  • [IMPROVEMENT] When using certain versions of Rubygems (< 3.4.9), some users experienced a Rubygems bug in which the wrong version of Psych native extensions were loaded during Skylight's native extension building. We have inlined the data needed to download libskylight, so YAML is no longer required during installation. Note that for existing versions of Skylight, this issue may also be corrected by updating Rubygems to at least 3.4.9.

6.0.1 (September 12, 2023)

  • [BUGFIX] Fix a logger message that could raise an error when I18n is misconfigured or unconfigured.
  • [BUGFIX] Fix an issue with proxy config in skylightd.

6.0.0 (September 11, 2023)

  • [BREAKING] End support for Ruby 2.6
  • The following libraries are no longer tested and are not guaranteed to work with Skylight 6:
    • Sinatra 1.x
    • GraphQL 1.7 and 1.8
    • Sidekiq 4
  • NOTE: There is an inconsistency in the order of application of ruby2_keywords and instrument_method in Ruby >= 3.2. We recommend not combining these two annotations at all, but if you must, call instrument_method after your method has been defined.
  • [IMPROVEMENT] When Rails's exceptions_app (used by ActionDispatch::ShowExceptions) is set to another instrumented responder (like a Rails router), Skylight will not set the endpoint name after exception processing has started. This means that error traces will now be aggregated under the original endpoint that generated the error (but with the 'error' segment), rather than under the exception handler's controller and action name.
  • [IMPROVEMENT] (Once again) Provide native support for FreeBSD.
  • [BUGFIX] Fix an issue in which the daemon could time out if the processes file descriptor count was set very high (e.g. on Heroku's Performance dynos)
  • [IMPROVEMENT] Better support for GraphQL versions >= 2.0.18.

5.3.5 (January 18, 2024)
