v0.5.0

Compare Source

v0.4.52...v0.5.0

The 0.5.0 release is the next major release of mdBook, containing over 130 PRs since 0.4.52! The primary focus for this release has been an evolution of the Rust APIs to make it easier to maintain, to evolve in a backwards-compatible fashion, to clean up some things that have accumulated over time, and to significantly improve the performance and compile-times.

This release also includes many new features described below.

We have prepared a 0.5 Migration Guide to help existing authors switch from 0.4.

The final 0.5.0 release only contains the following changes since 0.5.0-beta.2:

• Added error handling to environment config handling. This checks that environment variables starting with MDBOOK_ are correctly specified instead of silently ignoring. This also fixed being able to replace entire top-level tables like MDBOOK_OUTPUT.
