This is a small release with bug fixes/updates and some new features. You can get it from the below link: https://github.com/namhyung/uftrace/releases/tag/v0.19 uftrace dump command that generates chrome trace output format supports adding source file and line number information. $ uftrace dump --chrome --srcline Also it now shows the timestamp as realtime with UTC offsets so that it can correlate trace output with external events easily. And it has a new script to show function execution time percentiles (P90, P95, P99). $ uftrace script -S scripts/func-percentile.py $FUNCNAME As more useful scripts are added, we'll need to think about how to deploy them. And there are a couple of important bug fixes. PLT functions generated by mold linker have different code patterns and cause uftrace crash. Now it's fixed and trace them correctly. And it checks RISC-V 64 CPUs properly in the hashmap code. And there are more bug fixes and improvements. Thank you all for making uftrace more useful, efficient and portable! Namhyung
