19.3.0

Features

• titers: Support parsing of thresholded values (e.g., "<80" or ">2560"). #1118 (@huddlej)
• tree: Support bootstrapped trees generated with RAxML via user-provided --tree-builder-args. #1127 (@tsibley)

Bug Fixes

• utils: Serialize common numpy data types in write_json. #1119 (@victorlin)
• filter: Standardize exit codes from internal error handling. #931 (@victorlin)
• tree: Suppress the Cannot specify --substitution-model unless using IQTree warning when --substitution-model is left at its default. #1127 (@tsibley)
• tree: Print the underlying error message when tree building fails. #1127 (@tsibley)
• Previously, numpy and scipy were installed as dependencies of dependencies. Mark them as direct dependencies since they are used directly within Augur. #1120 (@victorlin)

19.2.0

Features

• titers: Allow users to specify a custom prefix for attributes in the JSON output (e.g., cTiter can be changed to custom_prefix_cTiter). #1106 (@huddlej)

19.1.0

Features

• io: Add open_file and write_sequences to the Python Pubic API. #1114 (@joverlee521)

19.0.0

Major Changes

• io: Only read_metadata and read_sequences are available as part of the Python Public API. Other Python API functions of the augur.io module are no longer directly available. This is a breaking change, although we suspect few users to be impacted. If you still need to use other imports in your scripts, they can be imported from the Developer API but note that they are no longer part of the Public API. #1087 (@victorlin)

Bug Fixes

• docs: Update the API documentation to reflect the latest state of things in the codebase. #1087 (@victorlin)
• Fix support for Biopython version 1.80 which deprecated Bio.Seq.Seq.ungap(). #1102 (@victorlin)
• export v2: Fixed a bug where colorings for zero values via --colors would not get applied to the exported Auspice JSON. #1100 (@joverlee521)
• curate: Fixed a bug where metadata TSVs failed to parse if data within a column included comma separated values #1110 (@joverlee521)

18.2.0

Features

• Add the curate subcommand with two sub-subcommands, passthru and normalize-strings. The curate subcommand is intended to be a suite of commands to help users with data curation prior to running Nextstrain analyses. We will continue to add more subcommands as we identify other common data curation tasks. Please see the usage docs for details. #1039 (@joverlee521)

18.1.2

Bug Fixes

• traits: Fix trait inference when tips have missing values. #1081 (@huddlej)

18.1.1

Bug Fixes

• filter: Fixed a bug where --group-by week would fail when all samples in a chunk have been dropped due to ambiguous dates. #1080 (@victorlin)

18.1.0

Features

• filter: Add support to group by ISO week (--group-by week) during subsampling. #1067 (@victorlin)

Bug Fixes

• filter: Fixed unintended behavior in which grouping by day would "work" when used with month and/or year. Updated so it will be ignored. #1070 (@victorlin)
• filter: Fixed unintended behavior in which grouping by month with ambiguous years would "work". Updated so date ambiguity is checked properly for all generated columns. #1072 (@victorlin)

18.0.0

Major Changes

• export: The --node-data option may now be given multiple times to provide additional .json files. Previously, subsequent occurrences of the option overrode prior occurrences. This is a breaking change, although we expect few usages to be impacted. Each occurrence of the option may still specify multiple files at a time. #1010 (@tsibley)

Bug Fixes

• refine: 17.1.0 updated TreeTime to version 0.9.2 and introduced the refine flag --use-fft. This makes previously costly marginal date inference cheaper. This update adjusts when refine runs marginal date inference during its iterative optimization. Without the use-fft flag, it will now behave as it did before 17.1.0 (marginal inference only during final iterations). With the --use-fft flag, marginal date inference will be used at every step during the iteration if refine is run with --date-inference marginal #1034. (@rneher)
• tree: When using IQtree as tre builder, --nthreads now sets the maximum number of threads (IQtree argument -ntmax). The actual number of threads to use can be specified by the user through the tree-builder-arg -nt which defaults to -nt AUTO, causing IQtree to automatically chose the best number of threads to use #1042 (@corneliusroemer)
• Make cvxopt as a required dependency, since it is required for titer models to work #1035. (@victorlin)
• filter: Fix compatibility with Pandas 1.5.0 which could cause an unexpected AttributeError with an invalid --query given to augur filter. #1050 (@tsibley)
• refine: Add --verbosity argument that is passed down to TreeTime to facilitate monitoring and debugging. #1033 (@anna-parker)
• Improve handling of errors from TreeTime. #1033 (@anna-parker)

17.1.0

Features

• refine: Upgrade TreeTime from 0.8.6 to >= 0.9.2 which enables a speedup of timetree inference in marginal mode due to the use of Fast Fourier Transforms #1018. (@rneher and @anna-parker)

Bug Fixes

• refine, export v1: Use pandas.DataFrame.at instead of .loc for single values #979. (@victorlin)
• refine: Gracefully handle all exceptions from TreeTime #1023. (@anna-parker)
• refine: Document branch length units treetime expects #1024. (@anna-parker)
• dates: Raise an error when metadata to get_numerical_dates() is not a pandas DataFrame #1026. (@victorlin)
