Version 2.0.0 of tumblelog has been released
In the evening I pushed version 2.0.0 of tumblelog to GitHub. This version renders text after an image as a caption. Or, the following Markdown:

Photo of a cat resting.
Is rendered as HTML as follows:
<figure>
<img alt="Cat" src="cat.jpg" />
<figcaption>
Photo of a cat resting.
</figcaption>
</figure>
This allows for styling using CSS of both the image and the caption. You can see examples on this blog.
