+- Image dashboard now allows scrolling for large images (#2164) - thanks @lr1d
+- Scalar chart smoothing now caps at 0.999 for convenience (#1974) - thanks
+  @flostim
+- Scalar chart scroll-to-zoom behavior now requires holding `Alt` (#2221)
+- `tensorboard` now supports a `--version` command line argument (#2097) -
+  thanks @shashvatshahi1998
+- Python API now defines `tensorboard.__version__` in addition to
