Upgrade Notes

This is the result of github.com/Shopify/sarama using the github path as their canonical name in their go.mod file. Please see (IBM/sarama#1510) and (#672) for more details.

1.24.1

This release removes the WithValueTags option from the contrib/bradfitz/gomemcache integration.

WithValueTags could be problematic for multiple reasons such as producing unexpectedly large quantities of data, and possible security issues. We do not want to provide APIs with unexpected or potentially dangerous behavior.

Features

• contrib/gocql/gocql: update with latest changes to WithContext (#624) (Thanks @ericjster)
• profiler: add support for DD_ENV, DD_VERSION, DD_SERVICE, and DD_TAGS. (#632)
• ddtrace/tracer: add WithHTTPClient and increase default HTTP timeout (#636)
• contrib/bradfitz/gomemcache: trace item info for memcached operations (#642) (Thanks @mingrammer)

Fixes

• contrib/internal/httputil: only set status once with WriteHeader (#629)
• contrib/gocql/gocql: do not assume slice length (#641)
• profiler: use correct URL for profiler backend (#645)
• internal/globalconfig: fix wrong mutex acquired for SetServiceName (#659) (Thanks @vikpattabi)
