In an email to members, those behind the platform said the "site has been redesigned and rebuilt to make it easier to use and share your work".
New features include a publications directory and user directory, and the platform's home page now displays recently added articles by members.
The user directory allows people clicking on the site to browse the profiles of those journalists who have signed up and created a portfolio complete with bio and links to their work. The publications directory shows the titles members write for.
Journo Portfolio launched in December, and joins other portfolio sites aimed at journalists, including Cuttings.me.
Two months before Journo Portfolio launched, Journalism.co.uk published this list of five free portfolio and profile platforms for journalists.
