# 1.7.5

## Improvements

* `:tracing` plugin: make `Request#init_time` a UTC timestamp.

## Bugfixes

* fixed handling of conditional responses which was making a batch of concurrent requests being handled serially after they failed.
* `datadog` adapter: use `Request#init_time` as the span start time, which will fix the bug where the span wasn't including the time it takes to open the connection (TCP/TLS handhshakes).
