 This enables the `x86_64-unix` feature to have efficient implementations of various algorithms for `x86_64` CPUs on a Unix-like system. The 'unix' suffix indicates that the `UnixSeeder`, which uses `/dev/random` to generate random numbers, is activated as a fallback if no hardware number generator is available (like `rdseed` on `x86_64` or if the [`Randomization Services`](https://developer.apple.com/documentation/security/1399291-secrandomcopybytes?language=objc) on Apple platforms are not available). To avoid having the `UnixSeeder` as a potential fallback or to run on non-Unix systems (e.g., Windows), the `x86_64` feature is sufficient.

 In order to manage more complicated cases, another method called `Migrate On Read` can be used.
 
 Here is an example timeline where data is migrated only as needed with the `Migrate On Read` approach:
-- A new version of the `Application` is compiled, it has [email protected].2 as dependency (the dependency will have to be renamed to avoid conflicts, a possible name is to use the major version like `tfhe_0_4`) and [email protected] which will not be renamed and can be accessed as `tfhe`
+- A new version of the `Application` is compiled, it has [email protected].3 as dependency (the dependency will have to be renamed to avoid conflicts, a possible name is to use the major version like `tfhe_0_4`) and [email protected] which will not be renamed and can be accessed as `tfhe`
 - Code to manage reading the data is added to the `Application`:
 - The code determines whether the data was saved with the 0.4 `Application` or the 0.5 `Application`, if the data is already up to date with the 0.5 format it can be loaded right away, if it's in the 0.4 format the `Application` can check if an updated version of the data is already available in the 0.5 format and loads that if it's available, otherwise it converts the data to 0.5, saves the converted data to avoid having to convert it every time it is accessed and continue processing with the 0.5 data
 
 The above is more complicated to manage as data will be present on disk with several versions, however it allows to run the service continuously or near-continuously once the new `Application` is deployed (it will require careful routing or error handling as nodes with outdated `Application` won't be able to process the 0.5 data).
 
 Also, if required, several version of TFHE-rs can be "chained" to upgrade very old data to newer formats.
-The above pattern can be extended to have `tfhe_0_4` ([email protected].2 renamed), `tfhe_0_5` ([email protected] renamed) and `tfhe` being [email protected], this will require special handling from the developers so that their protocol can handle data from 0.4.2, 0.5.0 and 0.6.0 using all the conversion tooling from the relevant version.
