Changes in version 1.0.0 (2026-09-02)                  

update: 2026/08/04

New features

  - multinethist()
      - New implementation of Song and Olhede (2026+) for multi-layer
        network histogram estimation.
      - common_f option assumes a common graphon across layers.
      - Accepts a wider range of inputs: 3D array, list of
        igraph/network objects, and ergm.multi::combined_networks
        object.
  - nethist()
      - New method = "LSE" option, implementing Gao et al. (2015) for
        single-layer network histograms.
      - Now implemented as a single-layer wrapper around multinethist().
  - hnethist(): new hybrid network histogram method for shape-based
    model selection.
  - fitted(): new S3 method for nethist and multinethist objects.
  - New dataset: IndianVil, a multilayer network.

Renamed functions

  - summary() -> covariate_plot()
  - violin_netsummary() -> netsummary_plot()

Bug fixes

  - netsummary_plot() (formerly violin_netsummary()): return 0 instead
    of NaN when a subsampled network is empty.

Other changes

  - netsummary_plot(): x-axis values are now shown as igraph plots of
    v-shapes and cycles instead of labels.
  - Renamed output field LSE to MSE in nethist/multinethist objects.
  - Documentation terminology unified from "node" to "vertex".
  - multinethist(): reject plain matrix/Matrix elements in list input,
    since vertex ordering across layers cannot be verified.

                        Changes in version 0.2.4                        

update: 2023/04/04

-bug fix in plot()

                        Changes in version 0.2.3                        

update: 2023/03/15

  - Documentation updates
  - Internal functions (not visible to users)

                        Changes in version 0.2.2                        

update: 2022/12/08

  - plot.nethist()
      - You can display the estimated probabilities in p_mat of nethist
        objects by setting prob=TRUE. Use prob.col and prob.cex to set
        the color and size of text, respectively.
  - nethist()
      - Check the convergence criterion every 5 iterations from the
        fifth iteration (5,10,15,...) instead of every 5 iterations from
        the first iteration (1,6,11,...).
      - minor speed improvement.

                        Changes in version 0.2.1                        

update: 2022/11/26

  - Initialization step of nethist() is faster than earlier by computing
    hamming distance from the (simple) adjacency matrix instead of
    Manhattan distance.

                        Changes in version 0.2.0                        

update: 2022/11/19

  - Computation speed of nethist() and violin_netsummary() are improved.

Bug fixes

  - nethist(): computation of the diagonal part o in greedy search Rcpp
    routine is fixed.
  - nethist(): computation of log-likelihood when there is a smaller
    size of group is fixed, in greedy search Rcpp routine.

                        Changes in version 0.1.1                        

update: 2022/11/08

  - Documentations update: provide extra about default values of
    arguments, rewrite examples.

Bug fixes

  - Resolving default value issue of R in violin_netsummary().
