Jekyll 0.3 alpha out now

Jekyll 0.3 is a major advance from Jekyll 0.2. C code is now completely unannotated, and the system is now more tolerent of changes to code.

This is because Jekyll now uses a new non-determistic translation system. When translating one language to another, the translator produces a non-deterministic file that describes all the different ways that the file could be encoded. This non-determinism is then resolved by attempting to select the file that most closely matches the previous file.

Jekyll 0.3 coming soon

Jekyll 0.3 is a major step forward from Jekyll 0.2 as it uses a completely annotation-free encoding. We plan to release Jekyll 0.3 within the next few days.

Jekyll 0.21 alpha now out

Despite the .01 increment, this release contains quite a lot of changes under the covers. The C->Jekyll decoding system has been completely rewritten to use a more powerful transformational approach.

This has allowed us to change Jekyll's C encoding to be significantly lighter weight and less intrusive.

Jekyll 0.20 alpha now out

This change makes a number of major changes.

Translation from C to Jekyll to C is now able to preserve all information, including all layout changes, and changes to Jekyll-generated variable names. It does this by comparing with a previous version of the C file, and attempting to minimise the differences.

The encoding into C has also changed. The new encoding is much more lightweight, using less macros, and encoding more information with variable names.

Jekyll 0.17 alpha now out

There are no great new user-end features in this release - though quite a few new features are /almost/ ready.

The main purpose of this release is that it is a slight tidy-up of the version of Jekyll that the paper "Dr Jekyll and Mr C" was based on.

Website now in the CVS repository

The files used to generate the website are now in the Jekyll CVS repository, under the name "website".
