MathB 1.3.0

MathB 1.3.0 is likely the final update of MathB, a web-based mathematics pastebin service. The online mathematics pastebin service previously hosted at https://mathb.in/ has been shut down today after 13 years of continuous service. See the post MathB.in Is Shutting Down for more details about this. This release captures the state of this project as it was today at the time of shutting down the online service.

This update includes a few new features. For example, there is now a configurable runtime property named :expect that can be used to enforce the presence of certain tokens in the posts submitted by the users. This feature was used to enforce the presence of LaTeX delimiters in the online service, a measure that was instrumental in reducing spam to a great extent in the last few years. There are a few other minor changes too. See CHANGES.md for a detailed changelog.

The source code of MathB remains free and open-source, so anyone interested in hosting their own instance can still do so. To access the source code of MathB, please visit github.com/susam/mathb.
