Changes in version 0.3.0                        

This release adds a code-free app and reference-manager export.

  - [run_app()] launches a local, code-free Shiny app for building a
    search, retrieving records with a live progress terminal, and
    exporting them. A panel mirrors every choice as a runnable R script,
    so the app is an on-ramp to the package. It runs on your own
    machine, so the API key never leaves it. The app also has a Compare
    topics tab (with highlight, stability-band and counts-in-label
    controls, a per-term progress indicator, a quota estimate and a CSV
    export) and a Demo mode, on by default, that synthesises records and
    a comparison so the whole workflow can be explored with no key and
    no network. A new vignette, Using the code-free app, walks through
    every panel.
  - [as_bibtex()] and [as_ris()] export a record set to the BibTeX and
    RIS interchange formats, so a search can be carried into Zotero,
    EndNote, Mendeley or a LaTeX bibliography.
  - [plot_scopus_comparison()] now spreads the direct line labels
    vertically and draws a leader from each label to its line, so topics
    that converge near the final year no longer overlap, and falls back
    to a legend when there are too many topics to label legibly.

                        Changes in version 0.2.0                        

This release reaches further into the API and adds an analysis layer on
top of a retrieval.

  - [scopus_fetch()] gains cursor = TRUE, cursor-based pagination that
    retrieves a whole large query without the 5000-record ceiling of
    offset paging.
  - [scopus_abstract()] retrieves the abstract and fuller metadata for
    one or many records from the 'Scopus' Abstract Retrieval API,
    resilient to an identifier that cannot be found.
  - [scopus_trend()] reports annual record counts for a query (the size
    of a literature over time), with [plot_scopus_trend()].
  - [scopus_top()] tallies the most frequent sources or authors in a
    record set, with [plot_scopus_top()]. An autoplot() method draws a
    record set's publications per year.

                 Changes in version 0.1.0 (2026-06-20)                  

First release.

  - Reproducible search plans with [scopus_plan()], and cheap sizing
    with [scopus_count()].
  - Quota-aware, paginated retrieval through [scopus_fetch()], with the
    largest page each view allows requested by default to keep request
    counts low, and resumable, cached, partitioned retrieval through
    [scopus_fetch_plan()].
  - A stable normalised record schema from [scopus_records()], with a
    summary() method that gives a quick overview.
  - DOI extraction and change tracking with [scopus_extract_dois()] and
    [scopus_diff_dois()].
  - Topic-trend comparison with [scopus_compare_topics()], and a plot
    from [plot_scopus_comparison()] or autoplot().
  - Interoperability and I/O through [as_bibliometrix()],
    [write_scopus_records()] and [read_scopus_records()].
  - A reference to the common 'Scopus' field tags in
    [scopus_field_tags()], a safe query composer in [scopus_query()],
    and a bundled [example_records] dataset for offline exploration.
  - Safe merging of record sets with [scopus_combine()] (and a c()
    method), plus as_tibble() and as.data.frame() coercion.
  - A typed condition system (scopus_error and its subclasses) and
    quota-header parsing with [scopus_quota()].
  - The comparison plot uses whole-number year breaks, a
    colour-blind-safe palette, direct line labels, an optional highlight
    argument and a shaded Wilson stability band (an illustrative range,
    switchable with interval).
  - The bundled example_records spans several disciplines, and the
    examples and workflow vignettes draw on a wide range of fields.
  - Multiple authors are retained in the authors column rather than
    truncated to the first. Very large result totals are handled without
    overflow. DOI cleaning copes with www.doi.org hosts and DOI: labels.
