Thanks to Christopher Witte for raising these issues
* lisp/babel/langs/ob-haskell.el (org-babel-expand-body:haskell):
replaced missing () wrapping, and now using correct variable
expansion
(org-babel-execute:haskell): now using
org-babel-haskell-initiate-session to start sessions
(org-babel-haskell-initiate-session): only starting sessions if none
exists, also added a .25 second wait on brand new sessions to allow
the Haskell interpreter to fire up
(org-babel-load-session:haskell): now optionally accepts processed
params to avoid over-execution of variable resolution
(org-babel-prep-session:haskell): now optionally accepts processed
params to avoid over-execution of variable resolution, also placing
the variable definitions directly in the session instead of loading
them from a separate file
* lisp/org-entities.el (org-entities): Restructure the list.
(org-entities-help): Turn the help output into a buffer
in Org-mode, so that it becomes easier to find a symbol
in the structure.
(org-entities-create-table): Deal with new structure.
Thanks to Daniel Mahler for finding this problem and proposing the fix
* lisp/babel/ob.el (unless): ensure `declare-function' is available in
all Emacsen
A quick example of accessing remote json data from Babel code blocks.
Evaluate the following to see a listing of parks in DC by ward.
#+source: dc-parks
#+begin_src emacs-lisp :var keys='(ward address) :var data=json(url="http://ogdi.cloudapp.net/v1/dc/RecreationParks?format=json")
(append
(list keys 'hline)
(mapcar
(lambda (lis) (mapcar (lambda (key) (cdr (assoc key lis))) keys))
(cdr (car data))))
#+end_src
* lisp/org-macs.el (org-not-nil): Return the value if not interpreted
as nil.
* lisp/org.el (org-entry-get):
(org-entry-get-with-inheritance): Interpret the value "nil"
as nil for properties.

* lisp/org-macs.el (org-not-nil): New function.
* lisp/org.el (org-block-todo-from-children-or-siblings-or-parent):
Use `org-not-nil' to interpret a property value of nil.

The problem was here that the value of the property is the string
"nil", which is of course not nil.
This patches introduces a special case to interpret "nil" as nil.
* lisp/babel/langs/ob-emacs-lisp.el
(org-babel-expand-body:emacs-lisp): removed extra call to
`org-babel-process-params' which was causing referenced code blocks
to be run multiple times
(org-babel-execute:emacs-lisp): now passing processed-params through
to `org-babel-expand-body:emacs-lisp' which keeps references from
being evaluated multiple times
* lisp/org-agenda.el (org-agenda-get-timestamps): No errors
while getting TODO state.
(org-agenda-highlight-todo): No error when no keyword has
been matched.

Thanks to Bernt Hansen for pointing this out
* doc/org.texi (Languages): updating require statements for the next
org-babel syntax
(Batch execution): updating require statements for the next
org-babel syntax
* lisp/babel/ob-exp.el (org-babel-exp-results): now checking to see if
return value of `org-babel-ref-literal' is equal to the null
indicator flag -- meaning it's now possible to accept a value of
null
* lisp/babel/ob-ref.el (org-babel-ref-parse): now checking to see if
return value of `org-babel-ref-literal' is equal to the null
indicator flag -- meaning it's now possible to accept a value of
null
(org-babel-ref-literal): now returning a null indicator flag when
the value is *not* a literal value, meaning it is possible to pass
in a literal value of null
