1.1.1

Added entropyRate() for finite irreducible DTMCs, with configurable logarithm base and support for row- and column-stochastic storage.
Added kemenyConstant() for finite irreducible DTMCs, with support for both row- and column-stochastic storage and tests for the zero-diagonal hitting-time convention.
Hardened public R and native C++ entry points against invalid indices, negative sizes, integer overflow, and unbounded simulations.

1.1.0

Added exact and approximate lumpability tools.
Made hittingProbabilities() robust to arbitrarily small positive transitions by combining graph-based zero/one classification with a relative-residual Neumann iteration.
Added fundamentalMatrix() for finite absorbing chains, including support for column-stochastic storage.
Improved absorptionProbabilities() by solving (I - Q) B = R directly instead of explicitly forming (I - Q)^{-1}.

Added explicit structural-zero support to assessStationarity().
Statistical inference functions now return R-standard htest objects and use the standard print.htest() output, while retaining the legacy dof field for compatibility.
Standardized assessOrder() on the same htest convention, including parameter = c(df = ...) and the standard test output.
Expanded the statistical_analysis section with numerical test results and time-homogeneity examples.
Added published literature examples for non-rejection of the Markov property and for empirical-versus-theoretical transition matrices.
Corrected structural-zero regression tests and the assessStationarity() documentation example used by package checks.
Corrected verifyEmpiricalToTheoretical() to use row totals when constructing expected transition counts for its row-wise multinomial likelihood-ratio test. This fixes a historical use of column totals and changes the Kullback et al. benchmark from 6.551795 to 6.518384, without changing its inferential conclusion.
Added explicit absorbingStates support to markovchainFit() for MLE fits of sequence data with known terminal states.

Fix for numerical issues
Removed deprecated .Dim methods
Add check monotonicity
Fixed a division-by-zero vulnerability in the C++ backend of generatorToTransitionMatrix(). The function now safely handles absorbing states (where the diagonal element is exactly 0) without returning NaNs or crashing.
Optimized memory allocation in the internal C++ function clean_nas() (used by createSequenceMatrix() and other fitting functions). By pre-calculating the exact number of valid elements before array instantiation, the package now avoids continuous memory reallocations, resulting in faster parsing of large sequences containing NA values.
