Milestones
2.8.6

2.8.6

Open

Due by June 30, 2026

Last updated Jan 27, 2026

3% complete

(expected) Bug fixes for fallout possible due to "fightwarn" effort in 2.7.5/2.8.0 - a few were caught in 2.8.1 and 2.8.2, some issues from those were caught in 2.8.3...
(expected) Clean-up of basic data types usage (NUT string API and notably methods for numeric conversions, booleans, ...)
(expected) Dynamic Mapping Files (DMF) feature supported, to allow the driver binaries to be built once and data mappings to be loaded and modernized on the fly [Ported from 42ITy project, related to #1316]
(expected) Porting of remaining performance and bug fixes from 42ITy project, if any remain unported after 2.8.3
(expected) Review and possible porting of patches applied by packaged distributions of NUT
(expected) A NUT for Windows installer (notably to set permissions for USB IDs handled by NUT drivers)?
(expected) CI automation for coding style (clang-format)
(expected) CI automation for use of data points in drivers that conform to patterns defined in docs/nut-names.txt
(expected) Basic C/C++ code built for WIN32 getting on par with POSIX as much as possible (many ifdefs now skip the higher-hanging fruit)
