What's new in 7-Zip 24.05:
-
New switch -myv={MMNN} to set decoder compatibility version for 7z archive creating.
{MMNN} is 4-digit number that represents the version of 7-Zip without a dot.
If -myv={MMNN} switch is specified, 7-Zip will only use compression methods that can be decoded by the specified version {MMNN} of 7-Zip and newer versions.
If -myv={MMNN} switch is not specified, -myv=2300 is used, and 7-Zip will only use compression methods that can be decoded by 7-Zip 23.00 and newer versions. -
New switch -myfa={FilterID} to allow 7-Zip to use the specified filter method for 7z archive creating.
-
New switch -myfd={FilterID} to disallow 7-Zip to use the specified filter method for 7z archive creating.
