Changes in version 0.3.0 (2025-06-15)                  

NEW FEATURES

    o   
	b1dsp(), b2dsp(), gwb1dsp(), and gwb2dsp() terms have been
	added, paralleling their ergm counterparts.

BUG FIXES

    o   
	Multilayer and multinetwork terms and functions such as gofN(),
	will now produce a sensible message if passed networks without
	multilayer and/or multinetwork metadata they require. Thanks to
	GitHub user @liluqi1991 for flagging this issue.

    o   
	gwespL(), espL(), and other terms from that family now
	correctly recycle their Ls.twopath= argument: if only one layer
	specification is given, it is used for both legs of the
	two-path.

    o   
	Layer logic implementation was reversing the arguments of
	noncommutative operators and functions.

OTHER USER-VISIBLE CHANGES

    o   
	Layer() now consistently uses the network and vertex attributes
	from the first observed layer for everything, and ignores
	and/or overwrites those of the other layers.

    o   
	When nesting network-combiners such as Networks() and Layer(),
	it is now an error to attempt to reference them out of order.
	That is, Networks(Layer(...))~L(~N(...)) is no longer allowed,
	since the multilayer specification is performed within the
	multinetwork.

    o   
	Layer() and Networks() documentation now informs the user that
	the resulting data structure's vertex and network attributes
	should be treated as read-only. This may change in the future.

    o   
	Support for networkLite and other alternative implementations
	of network's API has been added.

    o   
	gwespL(), gwdspL(), gwnspL(), when fixed=FALSE and other
	functions using a cutoff now terminate with an error if they
	encounter a network that exceeds it.

    o   
	*degreeL() family of terms has been removed. It never worked
	correctly and does not have a clear use case.

    o   
	blockdiag and blockdiagTNT proposals have been removed, as
	their performance is no better than the DyadGen-based dyadic
	constraint proposals.

    o   
	twostarL() no longer require the type= argument if called on an
	undirected network.

C-LEVEL FACILITIES

    o   
	A number of improvements and optimizations to the multilayer
	API.

    o   
	The exported Layer Logic API has been documented.

                 Changes in version 0.2.1 (2024-02-20)                  

NEW FEATURES

    o   
	marg_cond_sim() now has an argument for how to handle when the
	constrained sample has a higher variance than the
	unconstrained. (Previously, it would always throw an error.)

BUG FIXES

    o   
	Fixes for documentation issues flagged by CRAN and
	compatibility with the latest roxygen2.

OTHER USER-VISIBLE CHANGES

    o   
	Some citations updated.

    o   
	When the optimized block-diagonal proposals encounter an
	initial network with off-block-diagonal edges, they no longer
	throw an error but rather use the ergm 4.6.0+ proposal
	declination API.

                 Changes in version 0.2.0 (2023-05-30)                  

NEW FEATURES

    o   gofN objects now how augment and autoplot methods for Tidyverse
	and ggplot2 diagnostics.

    o   plot.gofN() and autoplot.gofN() are now more flexible in how
	they label extreme points via the id.label= argument.

BUG FIXES

    o   Fixed how parallel processing settings are handled in gofN()
	and marg_cond_sim().

                 Changes in version 0.1.2 (2023-01-05)                  

BUG FIXES

    o   marg_cond_sim() now expects control.gofN() as its control=
	list.

    o   Some unit test tolerances have been loosed, making false
	positives less likely.

    o   Miscellaneous documentation fixes.

OTHER USER-VISIBLE CHANGES

    o   Tweaks to the combine_networks() API to make it more robust,
	space-efficient, and flexible; in particular to make it
	possible for tergm to depend on it rather than maintaining its
	own copy.

                 Changes in version 0.1.1 (2022-08-11)                  

NEW FEATURES

    o   
	In the Layer(nw, attrlist) specification, attrlist= can now be
	a named vector, in which case the layers are renamed
	accordingly.

BUG FIXES

    o   
	Tolerance for some tests of the N() operator has been
	increased. This fixes a sporadic issue on M-series MacOS
	systems due to using a different linear algebra library.

    o   
	A bug in gofN() for valued ERGMs has been fixed.

OTHER USER-VISIBLE CHANGES

    o   
	A number of optimisations in multilayer ERGM code.

    o   
	[Layer] Logic backend now uses integer arithmetic, for a
	significant speed improvement, at the cost of behaviour
	slightly inconsistent with R's, such as / behaving as %/%
	(integer division).

                 Changes in version 0.1.0 (2022-07-03)                  

NEW FEATURES

    o   
	Initial public release.
