Scs Versions Save

This release includes:

• A new SessionManager.HashTokenInStore option, which hashes the session token with SHA256 before passing it to the store. Thanks to @bramvbilsen for this.
• Support for Hijacker and Flusher interfaces for Go 1.20+ (fixes issues #188, #196, #186)
• Documentation improvements thanks to @Daniel-Sogbey.

• Added SetDeadline() method. Thanks @lwj5 and @fnoopv.

• The LoadAndSave() method has been rewritten, so that it no longer buffers responses (which should improve performance) and is now compatible with http.ResponseController.

Version 2.5.0 of SCS includes:

• Support for iteration over all sessions via the Iterate() method.
• New Token(), Deadline(), GetInt32(), GetInt64() and RememberMe() methods.
• Session stores which require a context.Context are now supported.
• New store implementations for Firestore, MSSQL, GORM and MongoDB.

Thanks to everyone who contributed to this release, especially:

• @gandaldf for updating all the session stores to support iteration, adding the MSSQL and BuntDB stores, and the many improvements to the documentation and stores.
• @jum for implementing the Firestore store, and the discussion around supporting context.Context in session stores.
• @joesonw for the PR to support context.Context in session stores.
• @cgossain for adding the MongoDB store.
• @lafriks for adding the GORM store.

• Fix data race in generateContextKey
• Improve test structure and add mockstore package
