zentraR 0.1.3

• Documentation and metadata polish for the first CRAN submission (title casing, an updated external documentation link). No user-facing code changes.

zentraR 0.1.2

• The interactive progress indicator now advances during the parsing of large pages: the running reading count climbs as records are processed, so a big single-device fetch is visibly working instead of appearing frozen between pages.

zentraR 0.1.1

• On a rate-limit 429, wait precisely until the server’s advertised next-allowed time (parsed from the response) instead of using blind exponential backoff, so throttled fetches resume as early as possible.
• zc_sync(max_active = N) fetches up to N devices concurrently — safe and much faster because the v5 readings rate limit is enforced per device. A round-based scheduler backs off and retries any individually rate-limited device without blocking the others. Defaults to 1 (sequential).

zentraR 0.1.0

• First release.
• Device discovery via zc_list_devices() (auto-paginated, optional expand metadata).
• Reading retrieval via zc_get_readings(): tidy long output, automatic next_token pagination, flexible UTC time windows, and rate-limit-aware retries. A live progress indicator (spinner with page/reading counts) is shown in interactive sessions; control it with the progress argument or options(zentraR.progress = ).
• zc_pivot_wider(), zc_error_codes(), and zc_label_errors() helpers.
• Incremental zc_sync() with pluggable stores: zc_store_rds(), zc_store_csv(), zc_store_memory(), or return-only (store = NULL). Shows a live per-device progress indicator in interactive sessions (progress argument to control it).
• Rate-limit / transient backoffs print a branded, plain-language message (e.g. “ZENTRA Cloud rate limit reached; waiting 60s before retrying”) alongside the client’s live countdown.
• Authentication via zc_set_key() / the ZENTRACLOUD_API_KEY environment variable.
• Vignettes: “Getting Started with zentraR”, “Working with Your Data in R”, and “Scheduling Automatic Syncs”.
