[!WARNING]
This release includes a breaking change since the last release.

What's Changed

v0.15.0 is now available. It does contain minor breaking changes to two Block Kit elements along with a lot of new functionality.

Breaking Changes

Block Kit - Rich Text Section Date Element

If you are using the RichTextSectionDateElement block kit element, there is a new field Format which is now required. It previously did not exist, but was marked as required in the Block Kit Documentation. Similarly, the function NewRichTextSectionDateElement function signature has been updated to require the new parameter. While this may not have previously worked, the non-backwards compatible signature change prompts it to be identified as breaking change.

Block Kit - Rich Text input Block Element

If you are using the RichTextInputBlockElement block kit element, the InitialValue field type has been changed from string to *RichTextBlock to provide a more strongly typed experience. If you were previously passing a pre-formatted JSON object you will need to update your input to use the RichTextBlock struct instead.
