With a many to many relation, e.g. SiteTree_MyRelation, and listing
them in your template then adding ?archiveDate=x in the URL, a SQL
error is shown because Versioned::augmentSQL() tries to query the
non-existent table "SiteTree_MyRelation_versions" assuming there's
versioning setup, but there isn't.
Rendering potentially 1000s of nodes can exceed the CPU and memory constraints
of a normal PHP process, as well as the rendering capabilities of browsers.
Set a hard maximum for the renderable nodes, deferring to a "show as list" action
in the main CMS tree. For TreeDropdownField, we don't have the list fallback option,
so ask the user to search for the node title instead.
Also makes both the "node_threshold_total" and "node_threshold_leaf" values configurable
Strictly speaking, no longer required since we auto-quote simple
field names in DataQuery now, but since the majority of sorts in core is
already quoted we should stay consistent.
- Renamed $minNodeCount to more accurate $nodeCountThreshold
- The $minNodeCount attribute wasn't properly respected
during actual querying, so SilverStripe would always traverse
the entire tree (and load all objects into memory),
before then marking nodes as "unexpanded", which prevents
them from actually being rendered.
- Fixes nodes on search results to be expanded by default
- Fixes nodes on search results to correctly ajax-expand
This is to fix a bug that caused CheckboxSetFields to throw an error
when trying to call this function when editing a new DataObject. This
occurred when using the advancedworkflow module.
Thanks to simonwelsh for the majority of the work on this fix.
Lazy loading no longer loads fields from the versions table when querying. This could lead to incorrect data being displayed if the data on the object and the version it pointed to did not match.
API methods to allow setting of the context of the query that generated the DataObject on that object (used by the lazy loading mechanism to correctly query the Stage, Live, or Versions tables)
See https://github.com/silverstripe/sapphire/pull/1178 for context.

This causes a 'Fatal error: Call to a member function hasMethod() on a non-object'.
This can happen when displaying a field in a gridfield on a belongs_to relationship.
+ has a special meaning in the URLs so overall it's a good idea to
strip them out. Otherwise they would need to appear in their ugly url
encoded form "%2B".

BUG Issue with deleted records not being queried properly.
API DataQuery::expressionForField no longer requires a second parameter. Rather the query object is inferred from the DataQuery itself. This should improve consistency of use of this function.
