3.2.0

Added

• Linux support for the core SwiftMETAR library and the decode-winds-aloft
  CLI. Conditional FoundationNetworking/FoundationXML imports and a
  String(localized:) shim cover the platform gaps. The METARFormatting
  module and the decode-metar/decode-taf CLIs remain Apple-only, as they
  rely on Measurement.FormatStyle, which open-source Foundation does not
  provide; all targets still build on Apple platforms.

3.1.0

Changed

• Adopted Swift's Approachable Concurrency upcoming-feature flags
  (NonisolatedNonsendingByDefault and InferIsolatedConformances),
  aligning the package's async execution semantics with modern Swift 6
  defaults. No public API signatures changed: the async from(string:)
  parsers and the from(xml:) AsyncStream producers behave the same
  from a caller's perspective.
• Dropped the now-redundant @preconcurrency qualifier from
  import RegexBuilder across all parser files. Sendability of the
  cached, actor-confined compiled regexes is still provided by the
  package's Regex: @retroactive @unchecked Sendable conformance, which
  is retained until the standard library conforms Regex to Sendable
  itself.

3.0.0

[3.0.0] - 2026-03-20

Added

• XML parsing for METARs and TAFs from aviationweather.gov cache files.
  • METAR.from(xml:) and TAF.from(xml:) return AsyncStream<Result<..., Error>>
    for resilient batch parsing with per-entry error handling.
• Winds aloft parsing.

Changed

• CLI tools (decode-metar, decode-taf) now support --format xml and
  --output json options.
• Log messages in CLI tools now go to stderr to keep JSON output clean.
• Updated to Swift 6.2.
• Added swift-format for code formatting.

Fixed

• Fixed CSV parsing for updated aviationweather.gov format (quoted raw text,
  separate station_id column).
• Fixed handling of TAF periods where the end date comes before the start date
  (e.g., crossing month boundaries).

2.0.1

Fixed

• Better handling of pressure tendency remarks ("5 group").
  • Pressure change value is negated for downwards trends.
  • Localized string fixed to indicate pressure value is a change.

2.0.0

  • Adds DecodeMETAR and DecodeTAF CLI tools to demonstrate formatting library.
  • Adds documentation for METARFormatting.
• Group now includes the raw text as text.

Changed

• NSLocalizedString usages removed in favor of xcstrings catalogs and
  String(localized:)
• Added Visibility.notRecorded case to differentiate "VSNO" from "M".
• Minimum OS versions advanced.
• Added some utility functions to Weather and Remark.
• Made Remark.Urgency sortable.

Fixed

• More lenient parsing of direction ranges.
• Removed unused Error case.
