Starting DataTables 1.10 development :-)
Removed: fnRender - fnRender was depricated in 1.9 and is now being completely removed here. Its always been a bit messy and is now superseded by mRender. The main reason for this is that DataTables use to take an independent copy of the input data source object / array. This is a performance hit and it means we can't do any binding to external objects (for example it makes Knockout integration almost impossible).
Removed: bUseRendered - with fnRender being removed, bUseRendered is irrelevent
Updated: With fnRender being removed we no longer need to take an independent copy of the data source object / array (since DataTables itself isn't ever going to write to it now - fnRender did and the copy was included so we didn't inadvertantly change a developers data source object without them knowing about it. This is no longer a problem, and in fact having it use the same data source object is extremely useful in many cases.
Removed: sName reordering on return from the server when server-side processing. This was depricated in DataTables 1.9 and is now removed. This was an inefficient way to supply data to the DataTable in an array that was out of order and the client-side would reorder the arrays into what was needed. The way to do this now is to use mData and JSON objects rather than arrays, as it provides much greater flexibility without a performance hit on the client-side.
Note: _fnColumnOrdering is left in place at the moment, although it may be updated as work progresses on 1.10 with regard to the increased use of column names.
Fix - docs: Need to escape the underscores for markup output when we now use.
Update: Significant update to how sorting is applied internally in DataTables - there is no difference to how the sort is actually done, with the single exception that the -asc and -desc are not depricated in favour of the -pre method only.

- With the introduction of the -pre method in DataTables 1.9, the -asc and -desc sorting functions became more or less redundant since they are simple comparisons (all of the complexity is now in the -pre formatting function). As such the call to the -asc / -desc method is overhead that really isn't needed, and this commit introduces a sort function that doesn't call the -asc / -desc methods, instead just doing the comparison itself. In tests, this relatively simple change leads to a performance improvement of around 15% in all browsers (it also has the side benefit of less operations, so IE8- will be able to sort larger tables before flagging up a slow script warning).

- We can't just remove the sorting method which will call -asc / -desc though since not all sorting plug-ins will have a -pre method. Therefore, for backwards compatiblity the old sort function (albeit updated for the changed variables) is retained. The backwards compatibality code adds around 300 bytes to the library, but this is an unaccounced change, so backwards compatiblity must be retained.

- The old sort method will be removed in v1.11. The -asc and -desc methods are now fully depricated.

- Altered the sorting method to flatten the aaSorting array since the introduction of aDataSort in v1.9 required an extra loop in several locations. The functionality is very useful, but the extra loop can be a bit messy and slightly hit performance, so it is now flattened to be a single array (with object information so it makes sense, rather htan array indexes!).

- Altered the order of sorting when building _aSortData since it was looking up the same variable smultiple times which really wasn't needed.

This is part of a small incremental changes plan for DataTables! There are still a huge number of things to improve in this area, but this is a nice clean up and a nice 15% sorting performance improvement to get us started :-).
Remove - asStripClasses backwards compatiblity. There was a typo for asStripeClasses back when it was first introduced, now here in 1.10 the patch that was used to allow both forms is removed.
Update media/src/core/core.info.js

Only set iStart once and only call fnFormatNumber once on iStart.
Update media/src/api/api.static.js

Slightly shorter method for checking the version (stops as soon as it reaches a version part that has a difference)
Update media/src/ext/ext.sorting.js

handle undefined values, skip toLowerCase call for empty strings
Update media/src/core/core.ajax.js

Remove unnecessary else(s)
Update media/src/core/core.draw.js

Remove check for iOpenRows !== 0, since it isn't really needed.
(the contents of the loop just won't execute)
Update media/src/core/core.draw.js

Remove unused variable
Update media/src/core/core.filter.js

Reorder things a little to simplify
Fix: Release is currently 1.9.4

component.json needs to reflect the current release, not the development version.

Merge branch 'master' of github.com:DataTables/DataTables
Dev - Remove reporting code from the Ajax draw update - don't need it after the change for 36076fc5c83cda9f22fa0580a6128dc3b4b90284
Update media/src/core/core.ajax.js

simplify conditions:
!A || (A && (B || C)
really is the same as:
!A || (true && (B || C))
which simplifies to:
!A || (B || C)
which simplifies to:

Dev: Simplify Ajax condition
New: The primary public interface for DataTables' initialisation options is now camel case parameters rather than the Hungarian notation that was used before. There are a number of reasons for doing this, the primary one being that the Hungarian notation used by DataTables is actively stopping people from using the library due to their aversion to using Hungarian notation. Without doubt the Hungarian notation used was a mistake (the reason it was used was that when DataTables was originally written, the company I worked for at the time required the use of Hungarian notation, and thus I was trained in it...).

Backwards compatibility issues: The main goal here (other than to use camel-case notation!) is to preserve backwards compatibility. Unfortunately this isn't 100% possible:
	- DataTable.defaults.columns has been renamed to be DataTable.defaults.column
		- Otherwise it conflicts with aoColumns in the defaults.

Without doubt this is going to be a long process - for example the unit tests and examples need to be completely updated for this change. The JSDoc comments have been updated, so the site should take care of itself for the most part, when released.

In terms of implementation, it is important to note that I have not broken backwards compatibility here - the way it is does is that the current defaults are retained, and a camel-case to Hungarian mapping is automatically generated and then applied to the objects given by the end user. This adds around 0.5K to the size of DataTables, but writing the mapping manually would require at least 3K, and changing DataTables wholesale to camel-case would utterly break backwards compatibility. This is the least 'evil' way to accomplish this. It is important to note that this is a step along the roadmap for DataTables - come v2 Hungarian notation will likely be dropped completely.

One important note to make about this mapping is that if you use camel-case DataTables will copy the value from the camel-case properties to their Hungarian counterparts, so you will end up with additional properties on your source object. As I say, this appears to be to be the least 'evil' option, although still not perfect itself. The challenges of working with legacy software and installs...!
