Changes in version 1.0.6                        

New features

  - sniff_trajectory_destination(): track where the papers of an
    incomplete trajectory (one that stops before the last year) end up.
    Takes a detect_main_trajectories() result and a traj_id, follows the
    terminal node's documents forward, and returns the final-year
    destiny vector, the dormant share, the dominant continuation group,
    and a per-year flow table. With the optional all_detected argument
    (all groups' detect_main_trajectories() outputs) it also resolves
    the destination at the trajectory level, identifying which living
    trajectory absorbed the stagnant one (destination_traj,
    continuation_traj).
  - plot_trajectory_destination(): render the destinations from
    sniff_trajectory_destination() as variable-width lines on a Sugiyama
    time layout, matching plot_group_trajectories_lines_2d(). Each
    destination is one line whose width tracks the papers carried;
    color_by switches between destination group and destination
    trajectory, and min_prop folds minor destinations into a grey
    (other) line.
  - plot_trajectory_handoff(): draw the stagnant trajectory and the
    trajectory that absorbed it as two timelines on a shared year axis,
    with an arrow at the handoff year.
  - sniff_citations_cycle_time(): new normalize argument ("none" |
    "domain") to divide each group's annual CCT by the per-year network
    median, enabling within-domain comparability following Lee (2024).
  - sniff_citations_cycle_time(): new dispersion argument (logical) that
    adds p25 and p75 columns to the returned data tibble, useful for
    detecting bimodal citation-age distributions.
  - sniff_citations_cycle_time(): new citation_scope argument ("global"
    | "local") to restrict CCT to intra-corpus citations. Currently
    supported for OpenAlex data; Web of Science data falls back to
    "global" with a warning.

                        Changes in version 1.0.5                        

Bug fixes

  - sniff_groups_terms(): replace base tolower() with
    stringr::str_to_lower() to avoid locale-dependent failures on
    non-ASCII UTF-8 text.
  - sniff_groups_terms(): fix tryCatch scoping bug where error-handler
    assignments to stats[[i]] were lost, causing purrr::map_int(stats,
    nrow) to abort the whole run on a single failing group. Skipped
    groups are now dropped cleanly via purrr::compact().

                 Changes in version 1.0.4 (2026-04-04)                  

New features

  - mixed_sort(): exported for external use, with improved
    documentation.
  - plot_group_trajectories_lines_2d(): new width_by_traj_size parameter
    to scale line width by trajectory size (default TRUE).
  - plot_group_trajectories_lines_3d(): new width_by_traj_size parameter
    to scale line width by trajectory size (default TRUE).

Improvements

  - Rewrite vignette with biogas dataset and gallery-with-code format.
  - Fix README: wrong package name and CRAN URL, add Features section.

                        Changes in version 1.0.2                        

New features

  - sniff_key_route(): support for multiple key-routes and natural group
    ordering.
  - sniff_key_route(): new compact_gaps and direction arguments.
  - sniff_entropy(): new mode and window_size arguments.
  - get_openalex_fields(): cache saved batches to skip duplicate API
    downloads.

Improvements

  - Optimize SPC and key-route search with pre-built adjacency lists.
  - Pre-render horizon plots to reduce gt object size in
    sniff_groups_attributes().
  - Improve key-route plot layout, axis labels, and data output.
  - Improve horizon plot x-axis: vertical year labels, removed title.
  - Use 95th percentile for entropy diff plot y-axis range.
  - Swap diff colors in index plots: red for negative, blue for
    positive.
  - Add y_limits_diff parameter to indexes_plots().

Bug fixes

  - Fix y-axis scale across entropy plots for group comparison.
  - Fix dplyr variable collision in sniff_key_route() group filter.
  - Fix rlang .env import to resolve R CMD check NOTE.
  - Fix plot issues: diff colors and same-year node spreading.

                 Changes in version 1.0.0 (2026-02-19)                  

  - Initial CRAN release.
  - Rewrite of sniff_key_route(), sniff_citations_cycle_time(), and
    sniff_entropy().
  - Added testthat test suite with 102 tests across 16 files.
  - Fix BibTeX parser for Windows CRLF line endings.
  - Fix CRAN check issues: Unicode chars, \dontrun examples, DOI URLs.
  - Replace \dontrun with \donttest in all examples.
  - Add error guards to vignettes to prevent crashes.

                        Changes in version 0.1.0                        

  - Initial development version.
  - Added sniff_key_route() function for main path analysis.
  - Includes visualization capabilities.
  - Implements methodology from Liu & Lu (2012).
