- V 0.5.0.0: Cleaned up parser error behaviour:
- Parsing errors are now more helpful with better positional information, using a modified
showParsecErr and a new showParsecErrOneLine.
- Breaking change: The type of
readCalCurve changed. It is now safe, returning Either String CalCurveBP. The old version is preserved in readCalCurveUnsafe.
- V 0.4.0.2: Support for
optparse-applicative-0.19.0.0.
- V 0.4.0.1: Support for
random-1.3. Now possible, because MonadRandom supports it as well (https://github.com/byorgey/MonadRandom/blob/master/CHANGES.markdown#062-5-march-2025).
- V 0.4.0.0: Another major update:
- Added more calibration curves next to
intcal20: shcal20 and marine20. Renamed the Currycarbon.CalCurves.IntCal20 module to just Currycarbon.CalCurves. In the CLI, --calCurveFile is now just --calCurve, and it allows to either select the different packaged curves or read arbitrary .14c files.
- Added a new CLI plot element to the output of individual dates.
renderCLIPlotCalCurve plots a relevant section of the calibration curve.
- Added the command line options
--noTrimCalCurve and --noTrimOutCalPDF to allow control over the pre- and post-calibration trimming behaviour for radiocarbon dates.
- Changed the way products between calibration expressions are computed in
evalCalExpr. Input expressions in a multiplication are now calibrated for the entire length of the calibration curve. This allows to compute proper products and not fail in case of non-overlapping output.
- Changed the way calibration curves are embedded in currycarbon. This now uses the brilliant
file-embed library.
- Changed the interface of the core calibration functions.
CalibrateDatesConf no longer includes the CalibrationMethod, so calibrateDates and evalNamedCalExpr functions need it as an extra argument. calibrateDateBchron and calibrateDateMatrixMult now take CalibrateDatesConf and not its individual elements.
- Moved from Float to Double for probability densities and all functions that interact with them.
- Added a new output option
--basicFile to the CLI to enable simple per-expression output: The minimum start and maximum end of the high probability density regions and the median age. In this context writeCalC14 was split into writeCalC14HDR and writeCalC14CalRangeSummary in the library.
- Added little axis labels (BC/AD) to the command line plot to improve readability.
- Changed the release pipeline: Now again with a windows executable. currycarbon-macOS was replaced by currycarbon-macOS-X64 and currycarbon-macOS-ARM64.
- Switched to a new GHC version (v9.6.6) and stackage resolver version (lts-22.43).
- V 0.3.0.1: The golden tests can not run on stackage as it stands, so I hid them behind an environment variable.
- V 0.3.0.0: Major update with multiple breaking changes and new features:
- Added a new mechanism to draw random age samples from a CalPDF (
sampleAgesFromCalPDF :: AgeSamplingConf -> CalPDF -> RandomAgeSample). This is available from the command line with the options samplesFile, --seed, and -n/--nrSamples.
- Added a new concept to the
CalExpr data type: Age ranges with uniform probability for each year in the range (TimeWindowBP and TimeWindowBCAD).
- Reworked the encoding and evaluation mechanism for calibration expressions:
- Introduced the
NamedCalExpr as a wrapper around CalExpr with an identifier, and then adjusted the ID generation for CalPDFs to prioritize this identifier.
- Reworked the CLI DSL to support a standardized configuration language syntax implemented in a new module
ParserHelpers.hs. This introduces a set of flexible functions (calExpr(), uncalC14(), rangeBP(), rangeBCAD(), sum() and product()) which generally complement the previously available syntax and operators. The old syntax is mostly preserved as syntactic sugar for the new, more standardized syntax. Unfortunately this is not entirely seamless: The change breaks some expressions that were valid before (e.g. "3000,30 + 3020,50"). They now require additional parentheses to pass (so e.g. "(3000,30) + (3020,50)").
- Added some unit tests to cover the increasingly complex DSL.
- Changed the output files from .csv to .tsv and to a more meaningful and consistent set of column names.
- Slightly adjusted the rendering of the pretty, human-focussed command line output.
- Updated and improved the command line documentation.
- Renamed some CLI arguments:
--calibrationCurveFile -> --calCurveFile
--calCurveSegmentFile -> --calCurveSegFile
--calCurveMatrixFile -> --calCurveMatFile
- Changed the CLI behaviour with
--calCurveSegFile and --calCurveMatFile: currycarbon now fails with these options if the first sample is not a single, uncalibrated radiocarbon date (so uncalC14()).
- Added a simple golden test system with some basic calls to the
currycarbon CLI tool.
- Switched to a new GHC version (v9.4.7) and stackage resolver version (lts-21.17).
- V 0.2.1.2: Maintenance: Switched to a newer compiler/resolver version, lifted some dependency restrictions, ran stylish-haskell on the entire codebase, updated the github actions, deprecated the haddock documentation for the dev version on GitHub.
- V 0.2.1.1: Lifted some restrictions regarding the upper version bounds of dependencies.
- V 0.2.1.0: Added a mechanism to detect terminal encoding and fall back on a simpler CLI plot if it is not UTF-8.
- V 0.2.0.1: Brought sample names back to default CLI output.
- V 0.2.0.0: Added sum (and product) calibration and made the necessary changes to various interfaces (including CLI) to make this functionality accessible.
- V 0.1.2.0: Added simple summary data (
CalRangeSummary with calibrated median age + begin and end of 1- and 2-sigma ranges) to CalC14 and the CLI output and plot. The latter got refactored and enhanced in the process. HDRs are now "ordered", so _hdrstart actually stores the older and _hdrstop the younger date.
- V 0.1.1.0: Complete rewrite of the CLI output handling to avoid a memory leak.
- V 0.1.0.0: Switch to PVP versioning (https://pvp.haskell.org/).

calibrateDates function with a new config data type CalibrateDatesConf.
- V 0.21.3: Refactored the calibration curve interpolation.

- V 0.20.2: Some performance improvements for the calibration of large numbers of dates.
- V 0.20.1: Better (parsing) error handling.
- V 0.20.0: Added an option
--allowOutside to allow for calibrations to run outside the range of the calibration curve.
- V 0.19.0: Added functionality to filter out dates outside of the range of the calibration curve and report an error in this case.
- V 0.18.0: Implemented calibration with a StudentT distribution to mimic Bchron and established that as the new default. Reimplemented the
--method option of the CLI tool to reflect that change.
- V 0.17.0: Changed argument order in the
CalCurve data type to adjust to the order in .14C files.
- V 0.16.0: Refactoring in the library to simplify and clarify the interface.
- V 0.15.0: Added another calibration algorithm (following the implementation by Andrew Parnell in Bchron) and a method switch for the CLI.
- V 0.14.0: Introduced strictness, which brought a significant increase in performance. See the discussion here: https://old.reddit.com/r/haskell/comments/picjy6/how_could_i_improve_the_performance_of_my/.
- V 0.13.0: Major rewrite with the vector library - includes multiple bugfixes, but is surprisingly slow.
- V 0.12.0: Renamed some core functions.
- V 0.11.0: Made calibration curve interpolation optional and turned it off by default.
- V 0.10.0: Simplified CLI interface by dropping the

--hdrFile output a lot more machine-readable.
- V 0.8.0: Added option
--calibrationCurveFile to calibrate with different calibration curves.

runCalibrate.
- V 0.7.1: Added type documentation with haddock and replaced the existing types with record types.
- V 0.7.0: Changed the date input interface once more.
- V 0.6.0: Changed the date input interface, because parenthesis can be part of valid lab numbers.
- V 0.5.2: Fixed parallel evaluation (deepseq forced memory-intensive, non-lazy behaviour).
- V 0.5.1: Added github release action (copied from poseidon-hs).
- V 0.5.0: Added file input for dates to calibrate.
- V 0.4.0: Made output calibrated dates negative numbers for BC and positive for AD - and adjusted HDR printing accordingly.
