-## v0.93.0 (2024-08-05)
 
-### Feature
+## v1.7.0 (2024-12-02)
 
-* feat(themes): moved themes to bec_qthemes
+### Bug Fixes
 
-This reverts commit fd6ae91993a23a7b8dbb2cf3c4b7c3eda6d2b0f6 ([`5aad401`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/5aad401ef8774c7330784f72cd3b9d8c253e2b6a))
+- **tests**: Add test for Console widget
+  ([`da579b6`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/da579b6d213bcdf28c40c1a9e4e2535fdde824fb))
 
-## v0.92.5 (2024-08-05)
+### Features
 
-### Fix
+- **console**: Add "prompt" signal to inform when shell is at prompt
+  ([`3aeb0b6`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/3aeb0b66fbeb03d3d0ee60e108cc6b98fd9aa9b9))
 
-* fix(spinner): stop timer on close event ([`30fef92`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/30fef929cf6fb4b73f48151c92a0ee54c734031d))
+- **console**: Add 'terminate' and 'send_ctrl_c' methods to Console
+  ([`02086ae`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/02086aeae09233ec4e6ccc0e6a17f2b078d500b8))
 
-* fix(status_box): fix cleanup of status box ([`1f30dd7`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/1f30dd73a9c1e3135087a5eef92c7329f54a604e))
+.terminate() ends the started process, sending SIGTERM signal. If process is not dead after optional
+  timeout, SIGKILL is sent. .send_ctrl_c() sends SIGINT to the child process, and waits for prompt
+  until optional timeout is reached. Timeouts raise 'TimeoutError' exception.
 
-### Refactor
 
-* refactor(queue): refactored bec queue to inherit only from qwidget ([`7616ca0`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/7616ca0e145e233ccb48029a8c0b54b54b5b4194))

+  ([`cffcdf2`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/cffcdf292363249bcc7efa9d130431d0bc727fda))
 
-### Fix
+This fixes the blocking "QDrag.exec_()" on Linux, indeed before the drag'n'drop operation was
+  started with a simple click and it was waiting for drop forever. Now there are 2 different cases,
+  click or drag'n'drop - the drag'n'drop test actually moves the mouse and releases the button.
