+Updates in Nsight Python 1.1.1
+==============================
+
+API Changes
+-----------
+
+- **Raise an error when no kernels were profiled**
+  (`#83 <https://github.com/NVIDIA/nsight-python/pull/83>`_):
+  :func:`@nsight.analyze.kernel <nsight.analyze.kernel>` now raises a
+  ``RuntimeError`` when no kernel launch could be attributed to any
+  :func:`nsight.annotate` region, instead of returning an empty DataFrame.
+  Previously, with the CUPTI backend this failed silently when CUDA was used
+  before the first profiled call.
+
+- **Warn on ignored annotation failures**
+  (`#83 <https://github.com/NVIDIA/nsight-python/pull/83>`_):
+  When an annotation created with ``ignore_failures=True`` raises, a
+  ``RuntimeWarning`` naming the annotation and the ignored exception is now
+  emitted. The measured metric for that run is still set to ``NaN``.
+
+Fixes
+-----
+
+- **Improved kernel-count and missing-report errors**
+  (`#83 <https://github.com/NVIDIA/nsight-python/pull/83>`_):
+  The errors raised when an annotation launches more than one kernel, or a
+  different number of kernels in different runs, now report the kernel and run
+  counts and suggest warming up code that autotunes on its first call. The
+  error raised when no NVIDIA Nsight Compute report is found now includes the
+  report path and the most likely cause.
+
+- **Plain-text output when stdout is not a terminal**
+  (`#83 <https://github.com/NVIDIA/nsight-python/pull/83>`_):
+  ANSI color and cursor-movement codes are only emitted when stdout is a
+  terminal. When output is redirected to a file, a pipe, or a captured log,
+  only the final progress bar is printed.
