Changes in version 0.8.2 (2026-01-16)                  

  - CRAN maintenance: Patch release for CRAN compliance. Fixed example
    in plot_map() to use internal dataset wq_demo instead of external
    file reference. All examples and tests now comply with CRAN policies
    (no local file dependencies, write only to tempdir). No API changes.

                        Changes in version 0.8.1                        

  - Fix (CRAN compliance): render_report() now copies the template to a
    temporary directory before rendering to comply with CRAN filesystem
    policies. All intermediate files generated during rendering are
    written only to output_dir (default tempdir()), never to the package
    installation directory. Tests for render_report() are now skipped on
    CRAN (skip_on_cran()) and use withr::local_tempdir() for proper
    cleanup.

                 Changes in version 0.8.0 (2025-11-17)                  

  - Data and documentation update: The wq_demo example dataset is now a
    subset of real data (from BURANHEM river monitoring, 4 points,
    years 2020–2024, 20 rows). Includes extra columns: rio, lat, and
    lon.
  - All examples and vignettes now use real, representative dataset
    (greater realism and reproducibility).
  - Documentation (R/data_wq_demo.R, inst/extdata/wq_demo_README.txt,
    vignettes, README) updated to reflect the change.
  - No API breakage; all functions and test expectations remain valid
    for the new dataset structure and size.

                 Changes in version 0.7.3 (2025-10-31)                  

  - Funções iet_carlson() e iet_lamparelli() agora aceitam data.frame
    com .keep_ids.
  - Conversão automática de formato BR ("," / "<" / ">") e de p_total
    (mg/L) → tp (µg/L).
  - iqa() mais robusto: alias temp para temperatura, numificação segura
    e reponderação com na_rm=TRUE.
  - Campos identificadores (rio, ponto, data, lat, lon) agora são
    automaticamente reconhecidos e preservados via .keep_ids.

                 Changes in version 0.7.2 (2025-10-22)

      - Updated inst/CITATION to use the modern bibentry() format
        instead of the deprecated citEntry().
  - Minor internal documentation updates (no API or functional changes).

                        Changes in version 0.7.1                        

  - Title field adjusted per CRAN request: now "Water Quality Assessment
    and Environmental Compliance in Brazil".

    context.
  - No changes in functions or internal code.

                        Changes in version 0.7.0                        

  - New functions param_analysis() and param_analysis_multi():
      - Enable detailed analysis of specific parameters by point, river,
        or group of points.
      - Support cross-comparisons (multiple parameters at one point or
        multiple points for the same parameter).
      - Include simple temporal trend detection and basic statistical
        summary.
      - Return standardized data frames compatible with visualization
        and reporting tools.
  - Automated tests for new modules (test-param_analysis.R,
    test-param_analysis_multi.R).
  - Code updated to meet CRAN best practices (all checks passed 100%
    cleanly).
  - Minor stability improvements in plot_trend() and plot_map()
    (controlled messages).

                 Changes in version 0.6.2 (2025-10-07)                  

  - Fix: resolved codoc WARNING for generate_analysis() (docs matched to
    code).
  - No functional code changes.

                        Changes in version 0.6.1

  - New function plot_trend():
      - Visualize time series for parameters (e.g., turbidity, OD, IQA).
      - Add trend lines by group/point using three methods:
          - Theil–Sen (robust to outliers),
          - OLS (ordinary least squares),
          - LOESS (smoothed curve).
      - Supports faceting by river/point and customizable number of
        samples.
      - Returns a ggplot object ready for plotting.
  - Updated documentation for plot_trend() with practical examples.
  - Updated pkgdown site with dedicated section for trend visualization.

                 Changes in version 0.5.1 (2025-10-01)

  - New: plot_map() — interactive map of sampling points using Leaflet
    (optional dependency via Suggests).
  - Examples wrapped in if (interactive()) / \donttest{} to avoid
    network calls on CRAN.
  - Tests: added skip_on_cran() and skip_if_not_installed("leaflet")
    guards for map tests.
  - Encoding hardening: replaced non-ASCII characters with \u escapes.
  - Dependencies: removed unused htmltools from Imports.

  - Added expanded acronyms and DOIs/URLs in DESCRIPTION.
