:report_deps
now reports all loaded applications at the time the:sentry
application starts. This is not a compile-time configuration option anymore.- Add the
mix sentry.package_source_code
Mix task. See the upgrade guide for more information. - Add
~r"/test/"
to the default source code exclude patterns (see the:source_code_exclude_patterns
option). :environment_name
now defaults toproduction
(if it wasn't configured explicitly and if theSENTRY_ENVIRONMENT
environment variable is not set).- Hard-deprecate
:included_environments
. To control whether to send events to Sentry, use the:dsn
configuration option instead.:included_environments
now emits a warning if used, but will still work until v11.0.0 of this library. - Hard-deprecate
:before_send_event
in favor of the new:before_send
. This brings this SDK in line with all other Sentry SDKs.
