Thanks to Bernt Hansen for reporting this.
* lisp/ob-python.el (org-babel-python-evaluate-session): Fix a few
related issues with :session :results value blocks, including broken
if-else statements, indented blocks with blank lines, and returning
the wrong value when underscore has been used.
(org-babel-python--eval-ast): New constant variable, a string
consisting of Python code to execute a source block using ast.
Previously, python blocks with parameters ":session :results value"
were entered line-by-line into the Python session, which could cause
issues around indentation and new lines. Now, such python blocks are
written to temp files, then the built-in ast python module is used to
parse and execute them, and to extract the last line separately to
return as a result. Introduces a change in behavior, requiring that
the last line must be a top-level expression statement if its result
is to be saved (otherwise, the result is None).
* lisp/org-element.el (org-element--parse-elements): Only ignore parts
due to folding, not because of fontification.

* lisp/org-element.el (org-element--current-element): Forbid
affiliated keywords for comments.
* testing/lisp/test-org-element.el (test-org-element/comment-parser):
Tiny refactoring.
The motivation is to avoid distinguishing between top-level comments,
which cannot have affiliated keywords, and other comments, which
could. Therefore, we keep a single type of comment.
* lisp/org-element.el (org-element-comment-parser): Top level comments
do not have affiliated keywords.
(org-element--current-element): Properly parse top-level comments and
top-level properties drawer.
(org-element--next-mode): Change signature.
(org-element--parse-elements): Apply signature change.
(org-element--parse-to): Apply signature change. Look for top-level
comments or properties drawer.
* testing/lisp/test-org-element.el (test-org-element/property-drawer-parser):
Add comment.
Initially, `org-element--current-element' would defer to
`org-get-property-block' to validate a property-drawer, which is the
wrong way to look at the low-level Org Element library. Also, it would
allow affiliated keywords, which is not possible.
* doc/org-manual.org: Add `:tree-type month' option for capture

A bug was squashed where newlines after insertion of document property
drawers wasn't handled correctly.
* testing/lisp/test-org.el (test-org/insert-property-drawer):
Add test to verify that the document property drawer is
inserted above keyword lines. Also fix the specification for
document property drawer so it doesn't remove existing blank
rows if inserted at the top of a buffer.
* lisp/org.el (org-insert-property-drawer): Make sure to add
newline after document property drawers.

addition to at headline level.
* doc/org-manual.org:
* etc/ORG-NEWS: Document new functionality.
* lisp/org.el (org-keyword-regexp): Define constant instead of
hardcoding.
(org-file-properties): Renamed, see next line.
(org-keyword-properties): Renamed from above. Due to the fact that
properties can be defined for the whole document using property
drawers this local variable needs a rename to make its name less
ambigous.

(org-at-property-block-p): New function to validate if point is at the
start of a property block.
(org-property-global-value): Renamed, see next line.
(org-property-global-or-keyword-value): Renamed from above to match
its functionality better.
(org-back-to-heading-or-point-min): New function to make a document

(org-up-heading-or-point-min): New function to make a document work as

* lisp/org-element.el (org-element--current-element): Can now detect
property-blocks before first headline according to it's positional
rules.
* lisp/org-attach.el (org-attach): Make it possible to call the
attachment dispatcher also before the first headline, since document
property drawers make attachments possible for the whole document

* lisp/org-capture.el: Modified only due to rename of function in
org.el.
* lisp/org-compat.el (org-file-properties)
(org-property-global-value): Renamed functions declared obsolete.
* testing/lisp/test-org.el (org/insert-property-drawer)

Additions of tests to check if they work before first headline.
(org/at-property-p, org/at-property-block-p, org/get-property-block)
(org/entry-get, org/refresh-properties): New tests
* testing/examples/property-inheritance.org: Switch from
property-keywords to a property-drawer in the testfile.
Functionality should be the same, but now using a document drawer
instead of property-keywords.
Reason for switching is that I'd like us to slowly depricate
property-keywords.
* testing/lisp/test-org-element.el:
* contrib/lisp/ox-taskjuggler.el: A comment is modified only due to
rename of function in org.el.

removed. Adding it back here, together with an optional flag to

To satisfy compatabilty issues with org-brain. Ref. thread here:
- https://github.com/Kungsgeten/org-brain/pull/203
* lisp/org-attach.el
Changed the way attachments deal with property-inheritance. It now
adheres to the =org-use-property-inheritance= setting by default but
it can be customized if needed (I recommend to enable it!).
The property ATTACH_DIR is deprecated in favour of the shorter and simpler
property DIR.
Added an explicit option to =org-attach= for unsetting
attachment-directories (i.e. remove DIR property and deal with the
attachments by interaction).
Added attachment link type with the prefix "attachment:".
Added customizations:
- org-attach-dir-relative
- org-attach-preferred-new-method
- org-attach-use-inheritance
- org-attach-id-to-path-function
Hooks added:
- org-attach-after-change-hook
- org-attach-open-hook
A new linktype "attachment" is added in order to reduce
link-duplication when wanting to link to files in attached folders of
nodes. This works for both ID and DIR properties. The goal is to
make the functionality for attachment links mirror the functionality
for file links.
* lisp/org-attach-git.el
New file, existing functionality. Code here has been factored out
from org-attach.el and if GIT-functionality is to be used this module
needs to be required sepatately. It extends org-attach by use of its
hooks.
Activating git functionality in org-attach is done by loading
org-attach-git from now on, instead of customizing a variable.
Naming of both functions and tests has been modified to match the move
of functionality into its own module.
* lisp/org.el
Inline images are shown also using attachment-links, exactly the same
as it works for file-links today.
Make org-open-at-point respect ARG when opening attachment-dir.
* lisp/org-compat.el
org-attach-directory has been deprecated in favour for
org-attach-id-dir. The new name matches its purpose better.
* lisp/ox-html.el
Export attachment links to images as inline images, in the same way as
file links work today.
* etc/ORG-NEWS
Mention the changes in this patch.
* doc/org-manual.org
The chapter "Refile, Copy, Archive" has been split into two separate
chapters.
- "Refile, Copy and Archiving" for information related to moving
existing data around.
- "Capture, Attachments, RSS Feeds and Protocols" for information
related to working with external data.
The attachment-part has been rewritten and extended to match the
changes in this patch.
The new attachment link type is mentioned both inside the attachments
chapter and in the chapter dealing with links.
Documentation related to external links has been improved.
* testing/lisp/test-org-attach-annex.el
Require org-attach-git instead of org-attach, since this file tests
the GIT-functionality.
* testing/lisp/test-org-attach.el
Add tests for org-attach.
* testing/org-test.el
Define a symbol for a file to test attachments with.
* testing/examples/*
A bunch of new example files and folders are created and are used in
testing of org-attach to verify its functionality.
* org-test.el:
Fix org-test-with-temp-text-in-file. Make it work with <point>, as
some tests already expect it to do! Also make it fail more gracefully
by still removing temporary buffers and files.
Improve org-test-in-example-file. Make it behave similar to
org-test-with-temp-text and org-test-with-temp-text-in-file, in that
it will return the last evaluated expression.
* testing/lisp/test-org-element.el
Fix a temp-text strings so that it doesn't have an initial newline.
* testing/lisp/test-org.el
Minor cleanup to align code-structure with other tests. Nothing
changes in the test execpt style.
* testing/lisp/test-ox.el
Fix a couple of temp-text strings so that they don't have initial
newlines.
** test-org-export/expand-include
Test specification was wrong, due to org-test-with-temp-text-in-file
not previously working with <point>. Since that is fixed in this
patch the test needed to be updated to match the expected outcome.
* testing/lisp/test-property-inheritance.el
Fix wrong file-header and file-ending.
