+# flowme 0.4.0
+
+A few changes to reflect our current usage of the flow
+
+* not using {conflicted} anymore. Instead, use the 
+  [conflicts.policy option](https://blog.r-project.org/2019/03/19/managing-search-path-conflicts/)
+  set to strict and rely on good-old library calls making use of `mask.ok`, `exclude`, 
+  `include.only` args to explicitly deal with conflicts.
+
+* keep using load_all for interactive use, and source to make everything available to 
+  {targets} (although this will generate warnings when running document or test)
+
+* add by default a .radian_profile file, for our vscode users
+
+# flowme 0.3.1
