Affected versions:   3.6.0 to 3.6.5
Status:   fixed (3.6.6)
Found/reported by:   a user, on 2023-05-04

Status:   fixed (3.5.2 and 3.6.3)
Found/reported by:   author, on 2022-06-05

Description:   the ability to define the external momenta is broken.
Affected versions:   3.6.0, 3.6.1, 3.6.2
Status:   fixed (3.6.3)
Found/reported by:   author, on 2022-06-04

Description:   index_offset statement cannot appear before partition statement.
Affected versions:   3.6.0, 3.6.1, 3.6.2
Status:   fixed (3.6.3)
Found/reported by:   author, on 2022-05

Description:   some models can be erroneoulsy classified as decomposable, and then the diagram generation may be skipped.
Affected versions:   3.6.0, 3.6.1
Status:   fixed (3.6.2)
Found/reported by:   a user, on 2022-05-10

Description:   user-defined model-constants are not processed correctly, and the program may crash.
Affected versions:   3.6.0
Status:   fixed (3.6.1)
Found/reported by:   author, on 2022-04-28

Description:   an error message that should point to the model-file points to some other file instead.
Affected versions:   3.5.0
Status:   fixed (3.5.1)
Found/reported by:   author, on 2022-03-12

Description:   forbidden characters (mainly Tab) are not detected in input files.
Affected versions:   3.4,  3.4.1,  3.4.2
Status:   fixed (3.5.0)
Found/reported by:   a user, on 2021-05-27

Status:   fixed (3.4.2)
Found/reported by:   author, on 2019-04-06

Description:   plink is faulty (with true).
Affected versions:   3.4
Status:   fixed (3.4.1)
Found/reported by:   author, on 2019-03-16

Description:   no diagram is generated if options nosnail and notadpole are both specified.
Affected versions:   3.4
Status:   fixed (3.4.1)
Found/reported by:   author, on 2019-03-03
Remarks:   in this case “notadpole” is redundant, and may be omitted.

Description:   the case where there is at least one field which does not appear in any vertex is treated incorrectly.
Affected versions:   0.5
Status:   fixed (0.6)
Found/reported by:   author, on 2018-06-05
Remarks:   this anomalous case may be unlikely to appear in practice, but...
