Nightly development build of MODFLOW 6.
The develop branch of the MODFLOW 6 repository contains bug fixes and new functionality that may be incorporated into the next approved MODFLOW 6 release. Minimal development distributions are posted regularly to nightly build repository — these should be considered preliminary, provisional release candidates for the next version of MODFLOW 6.
The nightly builds are available as operating-system specific distributions including binaries, MODFLOW 6 input/output documentation, development notes, and a code.json metadata file.
The binaries are built in develop mode.
Linux binaries built on Ubuntu 22.04 may encounter libc-related backwards-incompatibilities on earlier versions of Ubuntu or other Linux distributions. This distribution, the main MODFLOW 6 distribution, and the MODFLOW-USGS/executables distribution are built on Ubuntu 20.04 for broader compatibility.
Release notes summarizing the current development cycle's changeset are included in the nightly distribution. The distribution also includes a copy of the 'MODFLOW 6 – Description of Input and Output' document (mf6io.pdf).
Release tags are based on the date, with format YYYYMMDD. Nightly builds are retained for 30 days in the event that there are issues with the latest release candidate.
Any issues with the nightly build should be posted on the main MODFLOW 6 GitHub repo and flagged with the nightly build label.
