A dark high contrast theme, with greater contrast between foreground and background elements, is now generally available to all github.com users. Navigate to the "Appearance" page in your profile settings to choose the dark high contrast theme. This release also includes improvements to our color system across all GitHub themes.
The tag selection component on the GitHub Release Creation UI has been updated to now be a dropdown selector rather than a text field.
This new component is less error prone and more consistent with the overall design of github.com
