Part of the discussion in #798.

Emphasis pattern treats newlines as whitespace (#785)

2019-02-07T16:28:52+00:00

All whitespace characters should be treated the same by inline patterns.
Previoulsy, emphasis patterns were only accounting for spaces, but not
other whitepsace characters such as newlines. Fixes #783.

Collapse all whitespace in reference ids (#743)

2018-10-30T15:09:40+00:00

Previously only newlines preceded by whitespace were collapsed. Fixes #742.

Make ENTITY_RE support hexadecimal entities

2018-09-25T10:31:07+00:00

Fixes #712.

smart_emphasis keyword > legacy_em extension.

2018-07-31T15:40:59+00:00

The smart_strong extension has been removed and its behavior is now the
default (smart em and smart strong are the default). The legacy_em
extension restores legacy behavior (no smart em or smart strong).

This completes the removal of keywords.  All parser behavior is now
modified by extensions, not by keywords on the Markdown class.

Fix double escaping of amp in attributes (#670)

2018-07-29T18:44:18+00:00

Serializer should only escape & in attributes if not part of & 

Better regex avoid Unicode and `_` in amp detection.

In general, we don't want to escape already escaped content, but with code content, we want literal representations of escaped content, so have code content explicitly escape its content before placing in AtomicStrings.

Closes #669.

Consistent copyright headers.

2018-07-27T18:43:09+00:00

Fixes #435.

All Markdown instances are now 'md'. (#691)

2018-07-27T14:55:41+00:00

Previously, instances of the Markdown class were represented as any one 
of 'md', 'md_instance', or 'markdown'. This inconsistency made it 
difficult when developing extensions, or just maintaining the existing 
code. Now, all instances are consistently represented as 'md'.

The old attributes on class instances still exist, but raise a 
DeprecationWarning when accessed. Also on classes where the instance was 
optional, the attribute always exists now and is simply None if no 
instance was provided (previously the attribute wouldn't exist).

Replace homegrown OrderedDict with purpose-built Registry. (#688)

2018-07-27T14:23:55+00:00

All processors and patterns now get "registered" to a Registry.
Each item is given a name (string) and a priority. The name is for
later reference and the priority can be either an integer or float
and is used to sort. Priority is sorted from highest to lowest. A 
Registry instance is a list-like iterable with the items auto-sorted 
by priority. If two items have the same priority, then they are 
listed in the order there were "registered". Registering a new 
item with the same name as an already registered item replaces
the old item with the new item (however, the new item is sorted by
its newly assigned priority). To remove an item, "deregister" it by 
name or index.

A backwards compatible shim is included so that existing simple
extensions should continue to work. DeprecationWarnings will 
be raised for any code which calls the old API.

Fixes #418.

Moved enable_attributes keyword to extension: legacy_attrs.

2018-07-24T15:40:13+00:00

If you have existing documents that use the legacy attributes format,
then you should enable the legacy_attrs extension for those documents.
Everyone is encouraged to use the attr_list extension going forward.
Closes #643. Work adapted from 0005d7a of the md3 branch.
