 ## 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, which is still supported since the functions now take any number of string values, 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](https://github.com/newrelic/go-agent/issues/551).
