+---
+Due to requests of Anaconda environment users PyBuilder version 0.12.9 introduced a `--no-venvs` 
+option. This option turns off all Python virtual environment management implemented in 0.12.x 
+for those users who prefer (or must) manager their own virtual environments. 
+
+<!--more-->
+
+This feature essentially reverts PyBuilder v0.12.x to v0.11.x behavior.
+
+As in v0.11.x such behavior comes with very serious repercussions that include:
+* Pollution of Python environment with PyBuilder plugin dependencies potentially leading to unexpected and 
+unreproducible failures both in PyBuilder and in your project.
+* Pollution of Python environment with project artifacts, resulting in problems debugging and running tests.
+* Potentially inconsistent Coverage results arising from coverage tracked for files installed in the virtual
+environment rather than the source tree.
+
+If you decide to use `--no-venvs` option, please understand there are significant and potentially severe 
+consequences to code quality.
+
+Enjoy!
