 We've released a new profiling mode called **continuous profiling**. Read on to learn about the differences between transaction-based and continuous profiling mode.

+## Historical Context
 
 Transaction based profiling was the first profiling mode supported at Sentry, it simply means that any code executed between Sentry.startTransaction and transaction.finish is subject to being profiled. In this mode, all profiles are attached to transactions (and are even sent as part of the same envelope). This has the benefit of automatically profiling parts of the application that are actually instrumented while requiring no extra effort. This approach however has drawback that continuous profiling aims to address, one of the most obvious ones being that profiles cannot exceed 30 second durations.
