+- The workspace uses **version-specific manifests**: `Manifest-v1.12.toml`, `Manifest-v1.13.toml` and `Manifest-v1.14.toml`
 - Compat bounds in `Project.toml` use the form `"major.minor.patch"` — only bump them when the required version is actually registered in the General registry
 - When resolving `ERROR: empty intersection between Package@X and project compatibility Y`, check whether version Y is registered: `julia -e 'using Pkg; Pkg.Registry.update()'`, then inspect registry versions and delete the manifest if it is stale/conflicting (`rm Manifest-v1.12.toml; Pkg.resolve()`)
 - If the manifest is stale/conflicting, deleting `Manifest-v1.12.toml` and running `Pkg.resolve()` forces a clean resolution

 # Changelog
 
+## Unreleased
+### Added
+- experimental support for Julia 1.14 (compat bounds, default manifest, `bin/create_sys_image` and a CI job on Linux that may fail without failing the workflow)
+
 ## KiteControllers v0.4.2 - 2026-10-24
 ### Changed
 - the plot functions of the examples (before `examples/plot_functions.jl` and `examples/plot_helpers.jl`) moved to the new local package KitePlots in `lib/KitePlots`, which is part of the system image. Defined in `Main`, they could not be stored in it: the first plot of a log, e.g. with the OK button next to `plot_main` in the autopilot, took about 20 s to compile, mostly for the very large log type. The system image has to be created again with `bin/create_sys_image`
