[NTG-context] How to obtain older versions of LMTX?

Hi all, In order to circumvent a bug in the latest versions (2023-09-26 and 2024-01-08) of LMTX regarding math alignments, I am trying to get an older version of LMTX (from before September 2023) for MacOS ARM. Does any one know how to proceed? Thanks in advance. Best regards: Otared
