Changelog

Source: NEWS.md

Version 1.7.2.9000 (development version)

  • hardened td_get2(): downloaded/local CSV files are now validated (header and content) before replacing the cache, so HTML error pages, rate-limit responses and truncated downloads raise a clear error instead of silently returning (and caching) an empty data set
  • td_get2() cache is now tagged with its data source and format version; a cache produced from a different dataset_url is no longer reused
  • td_get2() reuses an already validated CSV from the same day instead of downloading it again, and falls back to the cached data (instead of erroring) when force_download = TRUE fails
  • td_get2() now retries downloads (3 attempts with backoff) and sends a package user agent, mitigating intermittent 429/connection reset errors from the portal
  • td_get2() no longer silently falls back to the default CKAN resource when an arbitrary dataset_url cannot be resolved; the fallback is restricted to the Tesouro Transparente portal and emits a warning
  • td_get2() asset code validation and filtering now share a single alias map, fixing the misleading list of valid codes in the error message and removing dead filtering code
  • td_get2() validates first_year/last_year and warns when the filters return no rows
  • fixed td_get() documentation pointing to an unreleased td_get2()
  • removed the optional MCP server (mcp_server(), mcp_tools(), and the bundled inst/mcp/tools.R definitions) along with the mcptools, ellmer, and jsonlite suggested dependencies
  • all internet-dependent tests now skip on CRAN and when offline (via testthat::skip_if_offline() and testthat::skip_on_cran()), while still running under covr
