Hi, For those interested: the new gretl4py-0.60 release is coming soon. Today I have uploaded fresh builds of version 0.52 for Windows (x86), Linux (x86), and macOS (Intel and Apple Silicon) here: https://sourceforge.net/projects/gretl/files/gretl4py/snapshots/ The most important changes are: 1. A new `gretl.Matrix` class. 2. The possibility to run hansl code, including scripts. 3. The possibility to pass Python lists to estimators, including functions provided by gretl packages. (That is: gretl.ols([1,0,2,3]).fit() which is an equivalent to gretl's 'ols 1 0 2 3'.) If you find any bugs, please report them. Best regards, Marcin
