ecodive 2.3.0

• Added ecodive JOSS citation information.
• New robust_aitchison() beta diversity function.
• Switch from testthat to dependency-free tinytest for test suite.
• read_tree fixes for edge cases.

ecodive 2.2.6 (2026-04-14)

• When using CLR normalization:

  • Warns when zeros are detected and pseudocount is NULL.
  • Then continues with pseudocount <- min(counts[counts>0]) / 2.

Breaking Changes

• norm now defaults to "none" instead of "percent".
• norm parameter was removed from some beta diversity functions.

ecodive 2.2.4

Breaking Changes

• The rarefy() function has been simplified:

  • drop = FALSE now returns samples with original counts when sum < depth.
  • drop = TRUE no longer drops zero-sum features - only zero-sum samples.
  • depth can no longer be a fraction (only positive integers now).
  • n_samples parameter has been removed.
  • warn parameter has been added.

ecodive 2.2.3

• Coerce counts to double before rarefaction.

ecodive 2.2.2 (2026-01-16)

• Drop explicit zeros from sparse matrices after rarefaction.

ecodive 2.2.1 (2025-12-12)

• Corrected CRAN rchk issue.

ecodive 2.2.0 (2025-12-03)

• Dedicated rarefaction backends for dense and sparse matrices.
• Auto-conversion to col-major sparse matrix for distance/diversity calculations.

ecodive 2.1.0 (2025-09-26)

Breaking Changes

• rescale parameter is superseded by norm parameter.

Fixes

• alpha_div() and beta_div() will only forward applicable parameters.
• No longer crashes when pairs = integer(0).
• pseudocount = NULL correctly selects smallest non-zero count.

ecodive 2.0.0 (2025-09-21)

Breaking Changes

• Input matrix is now samples as rows.
• Removed weighted parameter.
