## New features since last version update
+ - 3 July 2021: Allow optional prefixing of `hCoV-19/` to strain names when exporting Auspice JSON for visualization. This is specified via the config option `include_hcov19_prefix`. This is included in Nextstrain-maintained builds at the request of GISAID.
- 27 June 2021: Update clade definitions with 21G (Lambda, C.37) emerging from Peru and 21H (B.1.621) emerging from Colombia.
- 22 June 2021: Add the ability to specify subsampling via a `priorities.tsv` file. To use, set the `priorities > type: file` and add `priorities > file: path/to/priorities.tsv` to your build's `subsampling` schema. `priorities.tsv` contains `strain name\tarbitrary numerical value`. Higher values = higher priority. ([#664](https://github.com/nextstrain/ncov/pull/664))
- 18 June 2021: Change default behavior of frequency estimation to estimate frequencies starting 1 year prior to the current date. To override this default behavior, define a `min_date` in the `frequencies` section of the builds configuration. ([#659](https://github.com/nextstrain/ncov/pull/659))
