0.98.1

Tracer

Fixed

• Always include the whole of src/ in the Windows and PECL build (#2533)

Tracer

This release includes Windows dlls for the tracer starting with PHP 7.2. #2230

Windows support is in beta. We recommend carefully deploying the tracer to staging environments and testing it there before putting it to production. We are looking towards stabilizing Windows quickly, so any feedback and issue reports are welcome.

Added

• Enhance logging #2490
  • This features two new logging options:
    • datadog.trace.log_level allows more fine-grained control over logging (error, warn, info, debug, trace). It follows the RUST_LOG standard. Note that datadog.trace.debug still takes precedence if set.
    • datadog.trace.log_file allows specifying a dedicated target file for any datadog trace logs instead of the default php error location.
  • More log lines were added to allow for observing submitted spans (debug level) and hook invocations (trace level).
• Add http.route to Wordpress #2491

Changed

• Have datadog.trace.db_client_split_by_instance also affect mysqli and sqlsrv #2508
• Record nested exceptions in the integrations #2514
• Evaluate numbers and bools in tags and metrics for sampling rules #2521

Fixed

• Access to undefined method attempts in LaravelQueueIntegration #2485
• Include generated curl_exec spans of curl_multi_exec() in metrics #2505
• Remove Symfony Command Hook After Execution #2492
• Add zend_try around closing and flushing spans #2507
• Make PDO split-by coherent with other DB split-by with service name flattening #2524

Internal

• No longer compile the mockgen as part of the rust build #2512
• Add TEA Benchmarks #2438
• Reduce CI and Local Flakiness #2496, #2518

Profiling

This release requires System INIs to be used to configure the profiler settings which control the enabling/disabling of individual features. If you are configuring the profiler using php datadog-setup.php config set, you should be fine. We recommend switching to use the config mode of datadog-setup.php to configure profiling.

Added

• Enable timeline by default #2480. This can be disabled by setting the INI setting datadog.profiling.timeline_enabled to 0 or false. Using the datadog-setup.php script is recommended, for example:

  php datadog-setup.php config set --php-bin all -ddatadog.profiling.timeline_enabled=0
  

• PHP ZTS support for CPU- and Wall Time profiling #2470
• Add exception message to exception sample (opt-in) #2434

0.96.0

Exception profiling is now enabled by default. You can manage it using the DD_PROFILING_EXCEPTION_ENABLED environment variable or the datadog.profiling.exception_enabled setting in the INI file. Although the DD_PROFILING_EXPERIMENTAL_EXCEPTION_ENABLED environment variable and datadog.profiling.experimental_exception_enabled INI setting still work, the new ones take precedence.

0.94.1

This release fixes a regression in the profiler which would make it emit profiles even though profiling is disabled.

Profiling

Fixes

• Do not emit profiles when profiler is disabled #2393

0.94.0

⛔ This release has a bug with the profiler where it produces profiles even if it's been configured to be disabled. A fix was released with version 0.94.1 and we encourage you to upgrade in case you have the profiler installed but disabled.

This release adds support to OpenTelemetry so that you can use the OpenTelemetry API to generate Datadog spans. This is off by default. Enable it with the environment variable DD_TRACE_OTEL_ENABLED=1 or INI setting datadog.trace.otel_enabled=1. Please, refer to the documentation to get started. Also, the tracer now generates 128 bits trace ids by default, in an effort to match OpenTelemetry standards.
