 ## Unreleased
 ### Changed
-- `d_delay_d_param` now applies the chain rule for delay components that respond to delays accumulated from earlier components (e.g. a binary delay's dependence on its evaluation epoch). Design-matrix entries for binary pulsars change at the ~1e-5 relative level. The parameter-independent ingredients are computed once per design matrix via the new `TimingModel.delay_deriv_chain`; the unused `acc_delay` argument of `d_delay_d_param` was replaced by the optional `chain` argument.
 ### Added
-- Support for hierarchical triple systems: a second (outer) binary component can be added via a `BINARY2` line with `_2`-suffixed orbital parameters (e.g. `PB_2`, `A1_2`). Outer orbit delay is computed before, and propagated into, the inner binary. Outer wrappers `BinaryDD2`, `BinaryBT2`, and `BinaryELL12` are provided. Delay derivatives account for the outer→inner coupling (chain rule through the previous delay). The projected semi-major axis includes a second time derivative `A1DOT2` (alias `X2DOT`).
-- Time-domain solar wind GP noise components: ridge, squared-exponential, Matérn, and quasi-periodic kernels
-- Documentation page explaining the time-domain solar wind noise model, its interpolation basis, and how it differs from the Fourier-basis noise models
-- `TOAs.get_tdb_seconds()`, returning the TDB times of the TOAs in seconds with a selectable dtype
 ### Fixed
-- Place ``solar_windx`` before the binary in ``DEFAULT_ORDER`` so SolarWindDispersionX delays and derivatives chain-rule through the binary the same way as ``solar_wind``.
 ### Removed

 ## [1.1.7] 2026-08-24
 ### Changed
 - Document Apple Silicon via native ``linux/arm64`` containers (`nanograv/ng20`) instead of claiming PINT cannot run there; Rosetta/osx-64 remains an alternative
