	(Herwig 7) NLO development.

	** Improvements for spin correlations
	A number of improvements have been made to handle spin correlations in the
	parton shower.

	** Setup file mechanism
	An isolated event generator can now be modified prior to generating events
	by providing an additional input file; also support for re-initalizing
	isolated event generators has been added in this course to support Herwig
	7's parallel integration modes.

	** Handling of weighted LHE events
	The handling of LHE events with variable weight (codes 3 and 4) has now
	been enabled, along with the full handling of multiple event weights down
	to the HepMC output.

	** LHAPDF6 handling

	boost's unittesting framework. They are only enabled, when configured
	--with-boost .

	* ThePEG-1.9.2 release: 2014-07-07

	** Better support for LHAPDF 6
	The LHAPDF interface now determines if version 6 is available and
	makes use of new LHAPDFv6 features.



	* ThePEG-1.9.1 release: 2014-04-30

	** Build fix for SLC6
	Fixed problems with a missing <algorithm> header in ACDCGen.h that affected

	** OS X Mavericks build fix for readline
	The problem of infinite hangs when linking against libreadline
	in Mavericks has been resolved.



	* ThePEG-1.9.0 release: 2013-10-28

	** Rapidity edge cases
	Changed behavior for vanishing pt in eta() and vanishing mt in
	rapidity(): no error is thrown, but a ridculously large rapidity is
	returned instead.

	** Command line interface
	Adding a tag of the form "#first-last" when running a
	MultiEventGenerator now allows to run a subset of the runs

	** Pre- and Posthandlers
	A warning is now issued if the same handler is inserted twice into
	a pre- or posthandler list.

	** Statistics fixes
	Various issues for the handling of statistics in the presence of
	negative weights have been fixed.

	** Rivet search paths
	A new interface RivetAnalysis:Paths allows more search paths to be
	added to the analysis finding routine. This supplements the
	RIVET_ANALYSIS_PATH environment variable.

	** Vertex classes
	A chain of sign and prefactor fixes has been implemented in the
	Vertex classes to correct various vertex structures in Herwig++
	conversions of Feynrules models.

	** Custom XComb objects
	Matrix element classes can built with customized XComb objects.

	** Reweighting of SubProcessGroups and projections
	Matrix element groups can reweight contributions in a
	SubProcessGroup and select one of the dependent subprocesses to be
	used as the hard one instead of the group in total.

	** Fuzzy cuts
	Jet cuts in the jet cut framework can be assigned a fuzzy shape to
	improve the stability of NLO calculations.

	** NLORivetAnalysis, NLOHepMCFile
	The NLOHepMCFile and NLORivetAnalysis classes have been added to
	allow Rivet to analyse NLO calculations which perform output for the
	subtracted real emission matrix elements as ThePEG::SubProcessGroups;
	individual subprocesses in these groups are flagged as correlated
	by being assigned the same event number.

	** C++-11 testing
	To help with the coming transition to C++-11, we provide the new
	--enable-stdcxx11 configure flag. Please try to test builds with
	this flag enabled and let us know any problems, but do not use this
	in production code yet. In future releases, this flag will be on by
	default.




	* ThePEG-1.8.3 release: 2013-02-22

	** Fixed HepMC status code assignment
	The incoming line to a technical vertex that only changes a particle's
	momentum is now labelled 11 (MC-internal) instead of 2 (unstable).



	* ThePEG-1.8.2 release: 2013-01-30

	** Changes to scheduled event dumps
	Set the EventGenerator option "KeepAllDumps" to keep all dump files
	of a run, labelled by event number. These scheduled dumps now produce
	a cleaned generator state between events.

	** SLHA block bug fix
	In some circumstances, the end of an SLHA block was not parsed
	correctly.



	* ThePEG-1.8.1 release: 2012-10-15

	** Repository changes

	*** Stable flag
	The behaviour of the 'Particle:Stable' flag has changed slightly. When
	all decaymodes are removed from a particle, the flag will be
	automatically set to stable. However, it still needs to be set unstable
	by hand when new decaymodes are added to a formerly stable particle.

	*** Search paths
	The search paths for reading input files are now saved in the
	repository.

	** Rivet analysis YODA capable
	The configure time check for Rivet will now detect the version to
	check if it is YODA capable.

	** NLOHepMCFile
	An AnalysisHandler, similar to the standard HepMCFile has been
	added to allow analysing plain NLO calculations by communicating
	each member of a subprocess group (typically real emission and
	subtraction contributions) to a HepMC file; until Rivet supports
	the correct treatment of errors in this case, the subprocess group
	members are written out as events independent of each other.

	** Jet cuts
	A more flexible framework for cuts on jets has been added,
	including jet finders (either builtin or via an optional link to
	fastjet). All kinds of exclusive and inclusive jet cuts, as well as
	jet vetoes on the level of the hard process are now supported.

	** Tree2toNDiagram
	A bug has been fixed in Tree2toNDiagram::isSame(tcDiagPtr,
	map<int,int>&) method to take into account symmetries when swapping
	two external legs attached to the same vertex

	** Quark thresholds in alphaS
	Support for setting quark masses for threshold matching in
	couplings deriving from AlphaSBase independently of masses used in
	ParticleData objects has been added. The O1AlphaS implementation is
	fully aware of this enhancement.

	** LesHouches reader fixes
	The LesHouches readers have been improved, and will spot many more
	consistency errors, such as coloured Standard Model leptons, or helicity
	values outside of [-1,1] and 9.

	** Spinor enhancements
	The LorentzSpinor class has gained member functions for projection operations
	and the contraction with the sigma-mu-nu commutator.



	* ThePEG-1.8.0 release: 2012-05-21

	** NLO support

	*** ThePEG now includes structures to ease implementing next-to-leading
	order (NLO) calculations as well as for interfacing external
	matrix element codes through runtime interfaces. Particularly,
	the newly introduced MEGroup and accompanying StdXCombGroup,
	StdDependentXComb and SubProcessGroup classes provide the
	functionality required by subtraction approaches to higher
	orders. A general interface for cutting on reconstructed jets
	as required by higher-order calculations is included, along
	with an implementation of kt, Cambridge-Aachen and anti-kt jet
	finding as relevant for NLO calculations. Hard process
	implementations deriving from MEBase are no longer limited to
	the evaluation of PDFs by PartonExtractor objects, thus
	allowing for a more flexible and more stable implementation of
	finite collinear contributioins appearing in the context of
	higher order corrections.

	*** The generation of phasespace points
	for the hard subprocess has been made more flexible,
	particularly to allow generation of incoming parton momenta by
	the hard matrix element as is typically done by phasespace
	generators provided with fixed-order codes. Along with this
	change, generation of the phasespace point does not need to
	take place in the centre-of-mass system of the incoming
	partons.

	*** Various helpers have been added to MEBase and dependent
	code along with the improvements described above, including
	simple functionality required for caching intermediate results.

	*** Tree2toNDiagram supports merging of two external legs,
	yielding another Tree2toNDiagram object to assist in
	determining subtraction terms required for a particular process

	** Support for SU(3)-sextet colour lines

	** Named weights support, also in HepMC
	Named, optional weights on top of the usual event weight are now
	fully supported; this includes their communication to HepMC events
	as well as their parsing from the extented Les Houches file format
	drafted at the Les Houches workshop 2009.

	** Complex masses supported in Helicity code

	** Several minor fixes and enhancements





	* ThePEG-1.7.3 release: 2012-03-05

	The only changes are in LesHouches.so, now at version 14.

	** Spin information
	Spin correlation information will now be set up correctly for tau
	leptons. To go back to the old behaviour, set
	LesHouchesReader:IncludeSpin No

	** Consistency checks
	Catch broken input where mother-daughter relations are circular.

	* ThePEG-1.7.2 release: 2011-11-01

	** HepMC configuration
	Clarified at configure time that HepMC versions before 2.05 are not
	officially supported.

	** Rivet configuration
	Rivet builds with external header dependencies are now correctly
	recognized.

	** Helicity vertex consistency
	To help debugging, the addToList() function for registering
	particle lines connected to a vertex now checks for electric charge
	conservation at the vertex. Additionally, the specified QED/QCD
	order of the interaction is checked.

	** Ticket #355: Global library list for resume functionality
	The list of global libraries is now correctly included in the dump
	file, to fix the functionality of resuming a run from regular
	checkpoints.



	* ThePEG-1.7.1 release: 2011-06-20

	** Ticket #238: Self-consistent electroweak schemes
	The default behaviour of Herwig++ is to use the best values for all
	the electroweak parameters, which can be inconsistent. Optionally
	now, a self-consistent electroweak scheme can be chosen in the
	parameter Model:EW/Scheme. Note that values of 'EW/Scheme' away
	from the default have not received the same amount of testing.

	** Ticket #338: Fixed reporting of floating point exceptions
	This was an issue whenever LHAPDF libraries were linked in.

	** Fixed cTau() behaviour
	The new behavior is that if both width and lifetime are zero,
	cTau() returns zero for unstable particles and MaxLength for
	stable ones.

	** MaxErrors
	The cutoff can be disabled by setting MaxErrors to -1.

	** StdOut redirect
	CurrentGenerator::Redirect now does not redirect to to the internal
	stream in EventGenerator if the useStdout flag has been set.

	** Run name tags
	Aded possibility to add a tag to the run name when running with the
	'-t' option. One run file can thus be run with different seeds and
	result in different output files.

	** Exception names
	EventGenerator tries to convert exception type names into
	human-readable form. Currently this only works for gcc-compatible
	compilers.

	** Repository API changes
	Instead of printing an error message to cerr, the
	Repository::load() and Repository::read(filename,os) commands now
	behave like the other repo commands and return an error string.
	This allows --exitonerror to work correctly for load() and read().
	Users of these functions need to send the string to cerr themselves
	if the old output behaviour is required.
	Repository::read(is, os, prompt) is unchanged.

	** HepMC precision
	The precision() option for HepMC GenEvent is now available as an
	interface in the HepMCFile analysis handler.

	** gcc-4.6
	The build has now also been tested with gcc 4.6.0.



	* ThePEG-1.7.0 release: 2011-02-08

	** Behaviour
	*** Cross-section information
	The .out file contains a better estimate of the cross-section
	directly from the phase space sampler. It should be reliable if
	not too many events were vetoed during the later phases of the
	production.
	*** Simpler decay mode selection
	Instead of having to turn off every mode individually, the new
	'SelectDecayModes' interface allows commands such as
	tbar:SelectDecayModes none
	tbar:SelectDecayModes tbar->nu_ebar,e-,bbar; tbar->nu_mubar,mu-,bbar;
	Use 'PrintDecayModes' to list the available choices.
	*** Rivet interface
	The interface will check before the run if all chosen analyses are
	actually available in Rivet, and will only call finalize() if any
	events have been generated. Event weights are now passed correctly
	into Rivet.
	*** Les Houches QNUMBER support
	QNUMBER particle creation support has been added to the Les
	Houches reader.
	*** Debug level
	If a debug level is set on the command line, it will always be used.
	*** Abort preserves events
	A hard abort exception during event generation will try to finalize as
	best as it can, thus preserving information about the run until this
	point.
	*** Progress log
	There is a new ThePEG::ProgressLog analysis handler, which prints
	timing information about the run to screen.
	*** Graphviz
	The event graph can show missing momentum information.
	*** CRLF line endings (Windows-style)
	File readers can now cope with files that have CRLF (Windows) and CR
	(Mac) line endings.


	** Structure
	*** Diffraction support
	To provide support for the simulation of diffractive events, the
	LeptonLeptonRemnant class was renamed to UnresolvedRemnant, the
	WeizsackerWilliams PDF extended, BudnevPDF added, and PartonExtractor
	modified to allow separate override PDFs for each beam.
	*** Polarized beams
	The PolarizedBeamParticleData class permits a spin polarization choice
	on the incoming particles.
	*** Mixing particles
	The MixedParticleData class supports mixed particle states.
	*** SpinBase
	The SpinBase class has been removed, SpinInfo is now the base class.
	*** Vertex classes
	Several new vertices were added for BSM physics, and some minor bugs
	fixed with existing classes.
	*** PID type
	Particle IDs now have their own type, 'PID'. It can only be converted
	to 'long' to avoid unsigned int overflow errors on 64bit machines.
	*** ClassDescription
	There is a simpler way to register ClassDescription information with
	the Repository: the DescribeClass<> template. No information is needed
	in the class headers anymore, reducing build dependencies. New code
	will use this method now, older classes will be migrated in future.
	*** LWH histogramming
	The built-in implementation of AIDA histogramming has been
	restructured slightly to decouple the implementation from the
	interface.

	** Build system
	*** Silent build rules
	'make' now builds silently, to improve readability. To get the old
	behaviour, run 'make V=1'
	*** zlib
	Integrated zlib to read compressed files, such as Les Houches events.
	*** Libtool 2.4
	Will fix some issues on OS X.
	*** gsl check
	This check now also works with Rivet


	** Bug fixes
	*** Ticket #286: Implementation of Cuts in LesHouchesReader
	Les Houches events are given in the lab frame, but QCDCuts expects to
	be given momenta in the parton-parton cmf. Boost added.
	*** Ticket #303: AlphaS thresholds
	AlphaS thresholds were fixed for exactly massless quarks.
	*** Ticket #304: Length units in HepMC
	*** Ticket #309: Particle initialization order
	*** Ticket #310: LeptonLeptonPDF fix



	* ThePEG-1.6.1 release: 2009-12-11

	** Ticket #292: Spin correlation fix to stabilize tau decay numerics
	We have restructured the spin correlation code to stabilize the
	numerical problems seen in tau decays.

	** Speed increase
	Improved decay chain handling speeds up a typical run by a few percent.

	** Exception logging
	The log file lists different exception types individually again
	instead of grouping them all by severity only. This was broken in
	the last few releases.



	* ThePEG-1.6.0 release: 2009-11-19

	** Helicity amplitudes
	The main change in this release is a streamlining of the helicity
	amplitude code. If you have self-written vertex classes, you will
	need to adapt them slightly:
	*** Spinor representation
	All spinors are now in HELAS representation, the optional
	representation switching has been removed.
	*** Adding particles to the vertex
	Instead of calling setList(v1, v2, v3) with three vectors of
	particles that need to be filled in sync, call
	addToList(p1, p2, p3) repeatedly.
	*** Name changes
	To make them consistent with the rest of ThePEG, the names of
	functions starting with get...() have changed:
	getFoo() becomes foo(); setFoo(...) becomes foo(...).

	** Vector code changes
	*** Vector3 has been renamed ThreeVector
	This makes it consistent with the other vector classes.
	*** LorentzVector::mag()/mag2() removed, to reduce confusion
	Use the equivalent ::m()/m2() instead to get E^2-p^2.
	LorentzVector::rho2() == ThreeVector::mag2() == p^2
	*** Calculating with a zero-length vector
	Previously, mathematically undefined values were arbitrarily set
	to 0 in this situation. Now an assertion failure is triggered in
	debug mode. Only the azimuthal angle phi() still returns 0.

	** Environment variable interpretation removed
	The programs setupThePEG and runThePEG are not wrapped in shell
	scripts anymore. All usage of environment variables at runtime has
	been removed. To influence the behaviour of ThePEG, you will need
	to use explicit command line flags, or calls to Repository::
	functions.

	** StandardModelBase now provides G_Fermi
	InvEnergy2 StandardModelBase::fermiConstant() const;
	provides the PDG 2006 value of G_Fermi.

	** Allow particle width cuts to be unset
	Setting a negative value for the lower or upper width cut removes
	that bound on the width.

	** Ticket #271: Decay mode names are normalized
	Previously, the ordering of decay products in a decay mode
	specifier needed to match ThePEG's internal ordering exactly. This
	is now done automatically.

	** Ticket #273: NoPDF and LesHouches reader
	The LesHouches reader has been fixed for the case where no PDFs are
	used in the LHE file.

	** Ticket #275: doinitrun() ordering
	The ACDC sampler now ensures that initrun() of all ME objects is
	run first.

	** Ticket #277: Repository command help texts
	ThePEG's repository command language now includes a 'help'
	functionality.

	** Redirection of various files
	The log file stream now goes to stdout instead of stderr when
	EventGenerator:UseStdout is set.

	** Readline support can be disabled
	Using the configure switch '--disable-readline', the linking of
	libreadline can be suppressed. This can be useful for batch code that
	will never be used interactively, if the number of linked-in
	libraries is a problem.

	** --with-LHAPDF configure flag
	Previously, the full LHAPDF path including lib/ needed to be
	specified. This now also works with the more common usage of just
	LHAPDF's prefix path.

	** Rivet analysis plugin
	The Rivet analysis output files are now named consistently like the
	other output from a run, with the run name as prefix.

	** Graphviz event visualization
	This is now independent of HepMC. The call to
	void ThePEG::printGraphviz(ostream & os, tcEventPtr event);
	on any event will output a Graphviz file to the stream,
	suitable for interpretation with the 'dot' tool. It shows a
	visualization of the generator's internal event structure, useful
	for debugging. This is an initial version, feedback is welcome!

	** Fixed compatibility with older HepMC versions
	A problem with rejecting a missing HepMC unit implementation was fixed.




	* ThePEG-1.5.0 release: 2009-09-01
	** New ZERO object
	The ZERO object can be used to set any dimensionful quantity to
	zero. This avoids explicit constructs like 0.0*GeV.

	** Readline interface
	The interactive repository access now uses the readline library,
	providing a command history and easier command line editing.

	** Syntax highlighting
	We now have a syntax highlighting mode for emacs. To enable it, use
	'M-x ThePEG-repository-mode' on any .in file.

	** Configure information
	Important configuration information is listed at the end of the
	'configure' run and in the file 'config.thepeg'. Please provide
	this file in any bug reports.

	** Rivet interface
	ThePEG now supports Rivet internally as an AnalysisHandler if it's
	available.

	** HepMC tools; CLHEP support removed
	The HepMC file output and graphviz event view have migrated from
	Herwig++ to ThePEG. The deprecated CLHEP support has been removed.

	** Exception specifiers removed
	Client code changes are needed in doinit() etc. Simply remove the
	exception specifier after the function name.

	** Support for HepMC 2.05
	*** New features
	ThePEG now supports cross-section output, PDF information and unit
	specifications if they are available in HepMC.
	*** IO_ASCII
	Support for the deprecated IO_ASCII format has been removed.
	*** Status codes
	ThePEG uses codes 1, 2 and 11 according to the HepMC agreement.

	** Redirection of .out, .log and .tex to stdout
	Set 'EventGenerator:UseStdout' to 'Yes' and (almost) all output
	will be streamed to stdout instead of files.

	** Ticket #248: Les Houches reader
	The cross-section information is now reported correctly when
	reading several files.

	** Cuts output
	If the debug level is set > 0, the current set of cuts is prepended
	to the logfile.

	** Preweighting of matrix elements
	A segfault when using preweights was fixed. Preweights are now
	correctly included in handler statistics.

	** Other technical changes
	*** Colour line improvements
	*** PDFsets.index search improved
	*** Ticket #232: Java check on OS X now works headless
	*** Running couplings restructured
	*** LeptonLeptonRemnant iprovements to support GammaGamma
	*** WaveFunction constructors streamlined
	*** VertexBase now provides sin2ThetaW etc.




	* ThePEG-1.4.2 release: 2009-05-08
	** Ticket #242
	Fixed a compiler problem that showed up on openSUSE 10.2, g++
	4.1.2. A source line was omitted if the optimization level was
	higher than -O1.

	** User interaction
	Dump file generation can now be disabled completely by setting
	EventGenerator:DumpPeriod to -1.



	* ThePEG-1.4.1 release: 2009-03-31
	** User interaction
	Error messages have been clarified in BaseRepository and
	StandardEventHandler

	** Les Houches files
	File readers are more robust, with clearer messages when things go
	wrong.

	** Floating point issues
	fixed in ThreeVector and VertexBase.

	** HepMC converter
	Fixed PDF choice for asymmetric beams.

	** Libtool
	Updated to version 2.2.6



	* ThePEG-1.4.0 release: 2008-12-02
	** Efficiency improvements
	The LorentzVector class, the helicity amplitude code and PDF
	lookups have been profiled and restructured to eliminate speed
	bottlenecks.

	** Deep inelastic scattering
	Support for DIS is now implemented in ThePEG.

	** New rapidity cut
	Added alternative pT cut that cuts on rapidity rather than
	pseudorapidty as the existing one fails for zero-pt massive
	particles.

	** HepMC units support
	Users of HepMC versions > 2.04 get full units support. The HepMC
	GenEvent object has the correct units set.

	** Support for HepMC PdfInfo data
	Users of the HepMC converter can now fill the PdfInfo data, which
	has been available since HepMC 1.28.00. Older versions are no
	longer supported.

	** Ticket #199: Particle lifetime cutoff
	Users can set a maximum lifetime. Particles that live longer than
	this are not decayed.

	** Ticket #215: Madgraph
	Fixed a problem in reading certain Madgraph event files.

	** Les Houches files
	Optional rescaling of energy or mass of particles which were read
	in. Check the file to trap 'nan' and 'inf' values early during the read-in.

	** File cleanup
	Most inline functions are now defined in the headers rather than a
	separate .icc file.



	* ThePEG-1.3.0 release: 2008-06-20
	** Statistical errors
	Error estimates on the cross-sections are now reported in the .out files.

	** Decaymode setup
	The decaymode setup has been reworked, keeping backwards
	compatibility. The 'defaultparticle' command has been removed.

	** Madgraph reader
	Updated to latest Madevent version.

	** LHAPDF improvements
	lhapdf-config is not used anymore to determine the location of the
	PDF sets. Instead, they are fixed at configure-time.

	** HepMC
	The beam particles are now set correctly.

	** Arbitrary search paths for .in files
	Input files don't have to be in '.', use '-I' to specify additional
	directories.

	** Ticket #172
	Fix for cuts in mirrored processes.

	** Simpler emacs macros
	The emacs macros have been significantly cleaned up.

	** Helicity vertex classes
	Potential prolems with uninitialized variables were fixed. No
	actual bugs had occurred from here.

	** Memory leak fixes and performance
	Several loops of shared pointers were fixed involving DecayModes
	and ParticleData. FixedSizeAllocator was removed, the regular 'new'
	and 'delete' is now used for all allocations, giving a 5% speedup.



	* ThePEG-1.2.0 release: 2008-04-18
	** ThePEG uses GSL
	The GNU Scientific Library and its headers are now required for
	building ThePEG. RandomGenerator partially uses GSL now.

	** Ticket #160: HepMC converter
	Optionally, the HepMC converter can fill an external GenEvent object,
	instead of newing one internally.

	** 'globallibrary' command
	The 'globallibrary' command can be used to register libraries which
	are useful for the whole run. They do not need to be listed in each
	class's library() function.

	** Resume from dump files (also solves #149)
	The --resume command line flag instructs runThePEG to resume the
	run from a previous dump file. 'set Generator:DumpPeriod 1000'
	writes such a checkpoint every 1000 events.

	** New Repository interface (also solves #141)
	The repository now provides a Repository::cleanup() method, to be
	called at the end of a run. Alternatively, a Repository object can
	be created and its member functions called.

	** Les Houches interface improvements.
	LesHouchesReader had had a major overhaul.

	** XSecCheck analysis
	Issues a warning if a target cross section is not met in the run.

	** Weighted events
	Handling of weighted events was improved.

	** Ticket #124: 'Deleted' interface option
	Interfaces can be declared obsolete, a warning will be issued when
	they're used.

	** LHAPDF interface
	The interface now allows photons as partons inside a hadron.

	** gcc 4.3.0
	ThePEG compiles cleanly with the new gcc 4.3 series.

	** Bug #138
	Lepton NoPDF now works.




	* ThePEG-1.1.2 release: 2008-02-25
	** Bug #136: dSigHatDR
	Efficiency improvement for zero PDF.

	** Bug #137: HepMC conversion
	The HepMC converter now takes a unit argument to specify which
	energy and length units should be used in the HepMC event.

	** Bug #140 / #141: Crash on shutdown
	This fixes a bug introduced in 1.1.1. External code interfaces
	should now work again.

	** Bug #151: Loop in Remnant record
	The loop between remnants in the event record has been removed.

	** PDF improvements
	Fix to handling of maximum flavour from LHAPDF. Fix for xmin
	calculation.




	* ThePEG-1.1.1 release: 2007-12-07
	** Bug #46: Reproducibility
	Fixed a problem where runs were not identical for a given random
	number seed. You now _must_ reset the seed if you need independent
	event generator runs.

	** Detection of gcc abs bug
	http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34130
	configure now checks for and works around the gcc abs() bug.

	** Separate LWHFactory library
	Fixed problem in Rivet interaction by factoring out LWHFactory into
	its own dynamic library.




	* ThePEG-1.1.0 release: 2007-11-20
	** New vector classes
	ThePEG now uses its own internal Vector classes, making it
	independent of CLHEP.

	** New dimension checking mechanism
	Optionally, any physical expression is checked for dimensional
	correctness at compile time.

	** Extended Helicity classes
	A full set of helicity amplitude classes has been transferred from
	Herwig++.

	** unlisted
	Many other improvements and small bug fixes, see ChangeLog.




	* ThePEG-1.0.1 release: 2006-11-22

	** unlisted:
	Fixed memory leak in LesHouchesReader.

	** Bug #58
	maximumCMEnergy() member of the EventGenerator returns zero. See
	ChangeLog entry 2006-10-06

	** Bug #62
	fixed 'const' behaviour in Lorentz spinor classes

	** Bug #68
	Improved error message for switch options

	** unlisted
	Improved compile-time LHAPDF library and include file handling.

	** unlisted
	Bug in IteratorRange::rrange(const Container &).

	** unlisted
	fixed Selector::swap()

	** unlisted
	Bug in ClusterCollapser where no colour-singlet particles were
	considered for momentum compensation if no coloured particles were
	present.

	** unlisted
	Bug in LeptonLeptonRemnant: minX variable not persistent

	** unlisted
	scale of the produced coloured particles was not set in
	Onium3GDecayer and ColourPairDecayer

	** unlisted
	unused default path removed from DynamicLoader
