Hi,
Dan and I are releasing some accumulated developments. They are
described below. We hope to now turn towards improving the
documentation and test framework, as we've developed much of it into
obsolescence.

- org-babel can now cache the results of source block execution to avoid
rerunning the same calculation. The cache uses a sha1 hash key of the
source code body and the header arguments to determine if
recalculation is required. These hash keys are kept mostly hidden in
the #+resname line of the results of the block. This behavior is
turned off by default. It is controlled through the :cache
and :nocache header arguments. To enable caching on a single block
add the :cache header argument, to enable global caching change the
value of your `org-babel-default-header-args' variable as follows
(setq org-babel-default-header-args
(cons '(:cache)
(assq-delete-all :nocache org-babel-default-header-args)))
- It is now possible to fold results by tabbing on the beginning of the
#+resname line. This can be done automatically to all results on
opening of a file by adding the following to your org-mode hook
(add-hook 'org-mode-hook 'org-babel-result-hide-all)
- allow header argument values to be lisp forms, for example the
following is now valid
:file (format "%s/images/pca-scatter.png" dir)
- aliases
- 'call' can now be used as an alias for 'lob'
- 'results' can now be used as an alias for 'resname'
- 'source' or 'function' can now be used as aliases for 'srcname'
