Release of FR5 v5.3.2b (3.21) & FR5 2022 Customer Survey

by FR5 | Jul 01, 2022

FirstRate5 v5.3.2b (3.21) is now available as a free download from www.fr5.com.au. Sustainability Victoria (SV) recommends that all users upgrade to this version.

This version includes a bug fix and a number of minor enhancements. Full details are available in the software release notes, which can be opened by clicking ‘Release Notes’ under the Help menu.

Below is a summary of key items included in FR5 v5.3.2b (3.21).

  •  Five new ceiling fan sizes have been added.
  • Functionality has been added on the Windows tab to allow users to hold shift and select/deselect all windows between two points.
  • A new default windows list named 'None' has been added. The 'None' list will be defaulted to when a window list is not already recorded in a user's profile settings file.
  • Fixed a windows list error that was causing intermittent calculation failures when project files were uploaded to the FirstRate5 website. This issue was only impacting files uploaded to the website and had no impact on files calculated locally.​​​

FR5 v5.3.2, FR5 v5.3.2a and FR5 v5.3.2b are all current versions of FirstRate5. Project files created in these software versions will continue to calculate automatically on the website.

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, eg,  v5.3.2a to v5.3.2b, will by default overwrite the previous version, while major releases involving a number change, eg, v5.3.1 (3.21) to v5.3.2 (3.21), will by default install beside older versions.
