Profiling (0.11.0)

Profiling is now installed and enabled when --enable-profiling is passed on the installer. Previously it was installed but not enabled. This removes one step in onboarding as the environment variable DD_PROFILING_ENABLED no longer needs to be set to 1, which can be difficult in some situations. The recommended way to configure profiling is to use .ini settings, which is generally easier.

Added

• Add .ini support #1775.
• Groundwork for allocation profiling #1794

Changed

• Bump libdatadog to 0.9 #1782.
• Bump env_logger to 0.9.3 #1804.

Internal Changes

• Add troubleshooting to README #1761

0.81.1

Fixed

• Fix span limiter not being reset in long running processes #1785

0.81.0

Traces disappearing

We have an issue causing span counters to not be reset properly after a flush. Thus the span limit of 1000 being reached, and then hooks not being executed anymore. This impacts long-running CLI processes only.
