Changes since 2.27.0

2.27.0

⛔ If you use the Continuous Profiler, please upgrade to v2.28.0 or greater. Release 2.26.0 introduced a native memory leak when using the Continuous Profiler.

⚠️ This release contains a known issue with DD_DBM_PROPAGATION_MODE. The issue is resolved in version 2.35.0.
Enabling DD_DBM_PROPAGATION_MODE may cause runtime errors in your application if you set the CommandType property on DbCommand to CommandType.StoredProcedure. If you suspect your application or a dependent library is using stored procedures, and you are currently using this release, don't enable DD_DBM_PROPAGATION_MODE until upgrading to 2.35.0+.
