+- April 27, 2026
+    + Fixes a bug where re-sourcing the script caused an infinite loop when Tab was pressed. Props to @maheshpec for [successfully diagnosing the problem](https://github.com/ohmyzsh/ohmyzsh/pull/13715).
+    + Fixes a bug where the completion widget was not identifying flags correctly.
 - March 31, 2026
     + When the user hits Tab after entering a command-line argument that uses spaces as wildcards (e.g., `z us lo bi`), the command line is clear of detritus (i.e., it looks like `z /usr/local/bin` instead of `z us lo /usr/local/bin`).
     + Improved test for Docker containers.
