Transition Arrangements for FR5 v5.2.11 (3.13)

As mentioned in previous communications, the NatHERS Administrator has advised Sustainability Victoria that the accreditation for FirstRate5 5.2.11 (3.13) has been extended to 1 August 2020. This extension will allow assessors to complete assessments already commenced using FR5 5.2.11 (3.13) and transition to FR5 v5.3.0a (3.21).

Assessors should use this transition period to finalise assessments already underway, rather than commence new assessments using FR5 v5.2.11 (3.13).
Until 1 August 2020 (5pm), a transition period will be in place. During this period v5.2.11 (3.13) files, v5.3.0 (3.21) files and v5.3.0a (3.21) files will automatically calculate on the FirstRate5 website.

After 1 August 2020 5pm, v5.3.0 (3.21) and v5.3.0a (3.21) files will continue to automatically calculate on the FirstRate5 website, however v5.2.11 (3.13) files will calculate by special request only.


Note: It is the user’s responsibility to ensure certificates are produced with the appropriate version. If a user chooses to inappropriately use an earlier version of FR5 to produce a certificate, they run the risk that a Building Surveyor will reject the certificate leading to further certificate costs.

Note: Installation of minor releases involving a letter change (e.g. v5.3.0 to v5.3.0a) will by default overwrite the previous version, while major releases involving a number change (e.g. v5.2.11 to v5.3.0) will by default install beside older versions.
