*** Regular Expressions
The addition of regular expressions marks a major improvement in usability.
+ *New* =regExp= class provides support for accessing POSIX extended regular
expresssions from within OpenFOAM.
See the manpages on your system (/man 7 regex/) for more information
about the extended regular expresssion syntax. Since entire strings are
matched, the =^= and =$= anchors are not required.
+ *New* =wordRe= class can contain a =word= or a =regExp= .
The match() method matches appropriately (as a =word= or as a =regExp=).

required.
+ *New* =wordRe= class can contain a =word= or a =regExp= . The match()
method matches appropriately (as a =word= or as a =regExp=).
+ *New* =stringListOps= to search string lists based on regular expressions,
=wordRe= or =wordReList= .
+ =Istream= and =Ostream= now retain backslashes when reading/writing strings.
The backslash continues to be used as an escape character for double-quote
and newline, but otherwise get passed through "as-is" without any other
special meaning (ie, they are /not/ C-style strings). This especially
helps with input/output of regular expressions.

*** Dictionary improvements/changes
+ Dictionaries can use words (unquoted) or regular expressions (quoted)
for their keywords. When searching, an exact match has priority
over a regular expression match.

+ The default =#inputMode= is now '=merge=', which corresponds to the most
general usage. The =#inputMode warn= corresponds to the previous
default behaviour.
+ The *new* =#inputMode protect= can be used to conditionally merge default
general usage. The =#inputMode warn= corresponds to the previous default
behaviour.
+ The *new* =#inputMode protect= can be used to conditionally merge default
values into existing dictionaries.
+ *New* =digest()= method to calculate and return the SHA1 message digest
*** Improved list containers
+ It is now possible to append a =UList= to an existing =List= or
=DynamicList= .
+ =DynamicList= is now much more flexible. It can be used with the
=append()= method, or with the =setSize()= method and =operator[]=, as
per =List= . =DynamicList= also has more methods for adjusting the
space allocated.

=List= . =DynamicList= also has more methods for adjusting the space
allocated.
+ =SortableList= now uses stable sort and allows =reverseSort()= as well.
=SortableList= is also more versatile - the indices mostly remain
unallocated until they are required in the =sort()= method.
The sort indices can be deallocated with the =shrink()= method.
Works as expected with =transfer()= and assignment from other lists.

indices can be deallocated with the =shrink()= method. Works as expected
with =transfer()= and assignment from other lists.
+ Specialization for =UList<bool>::operator[](..) const= to return =false=
for out-of-range elements. This allows lazy evaluation with no noticeable
change in performance.
+ =PackedList= has much better performance, *new* lazy evaluation and
*new* auto-vivify of elements on assignment. Any auto-vivified
elements will also flood-fill the gaps with zero. The =append()= method
can be used like in =DynamicList= to append a single element. The =set()=
method can be used like in =labelHashSet= .
A =PackedBoolList= can thus replace =labelHashSet= in many places.

+ *New* =UIndirectList= for an indirect list without storing the addressing.
*** New hashing algorithms
+ Bob Jenkins' hash routine for performance improvement (5-10% faster for
string hashing than the previous algorithm) and fewer collisions.
+ SHA1 hashing and SHA1 message digests (NIST specification FIPS-180-1)
added. The SHA1 digest provides a compact (20 bytes) means of
determining if the contents of an object have changed. The *new*
=OSHA1stream= class can be used to calculate SHA1 digests for anything
that can write to an output stream.

can be used to calculate SHA1 digests for anything that can write to an
output stream.
*** HashTable/HashSet improvements
+ Performance improvements for querying on empty tables
+ The =erase()= method can take a list of keys or the keys from any
another =HashTable=/=HashSet= .
+ =HashSet= has an =operator[]() const= that allows the same syntax
to be used for =boolList=, =PackedBoolList= and =labelHashSet= .

=HashTable=/=HashSet= .
+ =HashSet= has an =operator[]() const= that allows the same syntax to be
used for =boolList=, =PackedBoolList= and =labelHashSet= .
+ =HashSet has additional operators '+=', '-=', '&=' to add, remove or
intersect keys, respectively.
*** Improved bool/Switch
+ The =Switch= class has reduced the storage to be on par with =bool= .
It is now more flexible and behaves much more like a =bool= .
+ The =Switch= class has reduced the storage to be on par with =bool= . It
is now more flexible and behaves much more like a =bool= .
+ The IO for =bool= uses =Switch= internally for reading, so the end-user
doesn't need to know if a particular class used =bool= or =Switch= .
*** Miscellaneous container class improvments
+ *New* Boost-style =StaticAssert= added.
Which is useful to catch invalid template sizes, for example.
+ Various containers now have C++0x-style =cbegin()=, =cend()= iterator methods.
+ *New* Boost-style =StaticAssert= added. Which is useful to catch invalid
template sizes, for example.
+ Various containers now have C++0x-style =cbegin()=, =cend()= iterator
methods.
+ Various containers now have STL-style =empty()= method, which may be more
readable and universal than =!size()= or =!valid()= conditions.
+ various containers now have an =xfer()= method for yielding their contents
to a corresponding =Xfer= class.
*** *New* Xfer class
Provides finer grained control over copying or transferring objects with
very little overhead. It can be used for any object that has a =transfer()=
method and a =operator=()= copy method.
Since it is decided upon construction of the =Xfer= object whether the
parameter is to be copied or transferred, the contents of the resulting
Xfer object can be transferred unconditionally. This greatly simplifies
defining constructors or methods in other classes with mixed
transfer/copy semantics without requiring 2^N different versions.

different versions.
+ =xferCopy()=, =xferMove()= and =xferCopyTo()=, =xferMoveTo()= functions to
ease the use of the =Xfer= class.
*** Convenience changes
+ =IOobject= has a *new* constructor for creating an =IOobject= from a
single-path specification (eg, see =blockMesh -dict= option).
+ =argList= has *new* convenience methods for accessing options more directly:
=option()=, =optionFound()=, =optionLookup()=, =optionRead()=,
+ =argList= has *new* convenience methods for accessing options more
directly: =option()=, =optionFound()=, =optionLookup()=, =optionRead()=,
=optionReadIfPresent()= .
+ The *new* =readList(Istream&)= can read a bracket-delimited list or
handle a single value as a list of size 1. This can be a useful
convenience when processing command-line options.
+ The *new* =readList(Istream&)= can read a bracket-delimited list or handle
a single value as a list of size 1. This can be a useful convenience when

*** Misc. improvements
+ Improved consistency and interoperability between =face= and =triFace= classes.
+ =face::triangles()= can split and append to a =DynamicList=
+ =coordinateSystems= can access global systems (similar to =MeshObject=)
