rithikanarayan · purple4reina · web-flow · commit fc56ce1f086e · 2025-12-01T11:54:26.000-05:00
* first pass of adding runtime 3.14, checked against uses of 3.12

* snapshots

* removing comma

* Skip testing profiling for 3.14 runtime

* Updating asm to reflect dd-tract-py changes to http_utils._get_blocked_template

* pinning to older ddtrace

* Use pytest to skip profiling test

* Update version of black which supports python3.14

* Update linting to newest version of black.
