# Rcpi 1.41.3 (2024-09-09)

## Improvements

- Added early dependency checks for pwalign in functions that use
  pairwise alignment. If certain dependency conditions can't be met,
  the error is raised immediately, preventing unnecessary computation (#26).
- Replaced rjson with jsonlite to maintain compatibility with R < 4.4.0.
  The recent rjson update (v0.2.22 , 2024-08-20) requires R (>= 4.4.0),
  which would break builds on r-oldrel (#28).

# Rcpi 1.41.2 (2024-08-30)

## Improvements

- Since Bioconductor 3.19 and Biostrings 2.72.0, the pairwise sequence
  alignment facilities have been moved from Biostrings into the pwalign package.
  For maximum compatibility, we now detect the installed Biostrings version
  at runtime and decide which package to use for pairwise alignment,
  without introducing pwalign as an additional hard dependency.

  When calling `calcTwoProtSeqSim()` and `calcParProtSeqSim()`,
  if users have Biostrings >= 2.72.0 installed while pwalign is not installed,
  expect to see an explicit error in the results saying that pwalign is
  required and should be installed from Bioconductor.

# Rcpi 1.41.1 (2024-07-20)

## Improvements

- Replaced RCurl with httr2 and curl for retrieving molecular and sequence
  data from web APIs. Updated the outdated API endpoint URLs for DrugBank
  and RCSB PDB (#18).
- `inst/CITATION` now uses `bibentry()` to replace `citEntry()` (#19).
- Fixed check notes on lost braces when running `R CMD check` under R 4.4.x (#21).

# Rcpi 1.37.1 (2023-06-27)

## Improvements

- Migrate rcdk to a runtime soft dependency using rlang, to avoid build time issues.
- Migrate unit tests from using RUnit to testthat.
- Use GitHub Actions workflows for `R CMD check` and building the pkgdown website.
- Fix URLs that are broken or moved in the documentation.
