parca-agent - v0.11.0

Published by brancz almost 2 years ago

Breaking Changes

This release has a breaking change in the debuginfo upload protocol, which is only compatible with Parca server v0.15.0 or higher (more details in https://github.com/parca-dev/parca-agent/pull/1104 and https://github.com/parca-dev/parca/pull/2248).

What's Changed

Aside from the above-mentioned breaking changes, this release primarily improves resource usage required by the Parca Agent and iterates on the experimental DWARF unwinding support in various aspects working towards enabling it by default.
