      abstract     = {The HALHF collaboration has discussed a new baseline for
                      the project, taking into account comments from the
                      accelerator community on various aspects of the original
                      design. In particular, these concerned the practicality of
                      the dual-purpose linac to accelerate both colliding positron
                      bunches and the drive beams required for the plasma linac.
                      In addition, many other aspects of the project were also
                      considered; the discussion and conclusions are documented in
                      this paper. Finally, a new baseline is outlined that has
                      been optimised and addresses several weaknesses in the
                      original design, has higher luminosity, reduced
                      centre-of-mass energy boost and additional features such as
                      two interaction points and positron polarisation as well as
                      electron polarisation. Although HALHF has become longer and
                      more expensive, it remains significantly smaller and cheaper
                      than other mature Higgs factory designs currently under
                      discussion.},
