Problems with Symbols, High Severity (1)

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN2v811CpuProfiler14StartProfilingENS_6HandleINS_6StringEEEb to _ZN2v811CpuProfiler14StartProfilingENS_6HandleINS_6StringEEE. This may cause "undefined reference" linker error in old client applications.

Problems with Symbols, Low Severity (1)

	Change	Effect
1	Type of return value has been changed from enum CompressionAlgorithm to enum StartupData::CompressionAlgorithm.	Replacement of return type may indicate a change in its semantic meaning.
