Create a new instance from older package version

[orenyodfat]

app.sol enable creating a contract instance according to package name .
this will give always the latest implementation version of the specific package.

what will be the recommended approach to enable creating a contract instance from an older package versions ?

options:

• versioning via the package name - each package has its own version- not nice.
• bypass app.sol create function. get the package contract to get the specific provider for the require version.
• add version field to app.sol create function.

latest option seems to be cleaner.

I will close this issue here as it can be discussed in the forum.

Reopening issue to track adding a method to App.sol to create a contract from an older version natively. Alternatively, we could provide a library that takes care of this, to avoid polluting App itself.

Regarding use cases, see @orenyodfat answer on the forum:

There are few reasons why we would like to enable creation of contracts(in our case daos) from older versions : feature sets which was deprecated on new versions, using old safe audited contracts… and more.
