+# Vulkanite v0.1.1 release notes
+
+Vulkanite v0.1.1 improves active-tab visibility and gives LSP-tagged unnecessary code a quieter, dedicated presentation.
+
+## Highlights
+
+- Active native Neovim tabs now use Vulkanite's secondary teal accent.
+- Clean selected buffers in bufferline.nvim use the same secondary accent while retaining bold and italic styling.
+- Selected buffers with diagnostics continue to use their severity color, including vivid red for errors.
+- Code tagged unnecessary by an LSP now uses subdued slate grey while preserving its underlying syntax styling and diagnostic undercurls.
+
+## Integration and configuration
+
+- Added automatic and explicit highlight integration for bufferline.nvim.
+- Added `unnecessary` to the public `on_colors` interface so the diagnostic color can be overridden independently.
+
+## Requirements
+
+Vulkanite continues to require Neovim 0.10 or later with true-color support. The canonical repository is <https://github.com/kyerpotts/vulkanite.nvim>, and Vulkanite is released under the MIT License.
