3.18.1

Added

  • Extended the IgnoredPrefix configuration value for Code-Level Metrics so that multiple such prefixes may be given instead of a single one. This deprecates the IgnoredPrefix configuration field of Config.CodeLevelMetrics in favor of a new slice field IgnoredPrefixes. The corresponding configuration option-setting functions ConfigCodeLevelMetricsIgnoredPrefix and WithIgnoredPrefix now take any number of string parameters to set these values. Since those functions used to take a single string value, this change is backward-compatible with pre-3.18.1 code. Accordingly, the NEW_RELIC_CODE_LEVEL_METRICS_IGNORED_PREFIX environment variable is now a comma-separated list of prefixes. Fixes Issue #551.

Fixed

  • Corrected some small errors in documentation of package features. Fixes Issue #550

Compatibility Notice

As of release 3.18.0, the API was extended by allowing custom options to be added to calls to the Application.StartTransaction method and the WrapHandle and WrapHandleFunc functions. They are implemented as variadic functions such that the new option parameters are optional (i.e., zero or more options may be added to the end of the function calls) to be backward-compatible with pre-3.18.0 usage of those functions. This prevents the changes from breaking existing code for typical usage of the agent. However, it does mean those functions' call signatures have changed:

  • StartTransaction(string) -> StartTransaction(string, ...TraceOption)
  • WrapHandle(*Application, string, http.Handler) -> WrapHandle(*Application, string, http.Handler, ...TraceOption)
  • WrapHandleFunc(*Application, string, func(http.ResponseWriter, *http.Request)) -> WrapHandleFunc(*Application, string, func(http.ResponseWriter, *http.Request), ...TraceOption)

If, for example, you created your own custom interface type which includes the StartTransaction method or something that depends on these functions' exact call semantics, that code will need to be updated accordingly before using version 3.18.0 (or later) of the Go Agent.

Support Statement

New Relic recommends that you upgrade the agent regularly to ensure that you’re getting the latest features and performance benefits. Additionally, older releases will no longer be supported when they reach end-of-life.

See the Go Agent EOL Policy for details about supported versions of the Go Agent and third-party components.
