v1.0.0.21\/22 \u2013 March, 2026<\/h2>\n\n\n\nWhat’s New<\/h3>\n\n\n\n
Enhanced license management. This is a required update<\/strong> that will enable the software to switch to node-locked activations and deactivations. Node-locked licenses associate your software with a specific machine, allowing administrators to monitor who is currently active. This new licensing system will be fully implemented by the end of March 2026 and will necessitate that existing active users re-register, which will attach the machine name and Windows username to the license key. This is a one-time activation and will not be counted against the total permitted activations.<\/p>\n\n\n\n If your software fails to register it may mean that it has not been updated to the latest version. Click [Use Trial] instead. Then close and reopen the software to allow it to automatically update.<\/p>\n\n\n\n Studio Express 2026 mandatory update includes miscellaneous bug fixes, security enhancements and user interface improvements.<\/p>\n\n\n\n When working with Grate inlets on grade, the software now allows a Gutter Width to be greater than the Grate Width.<\/p>\n\n\n\n Security (code signing) update. A code signing certificate is a digital certificate that verifies the identity of a software developer and the integrity of their code. It’s used by developers to digitally sign software, drivers, and executables such as Studio Express. Corrected an issue related to weir coefficients not updating per user edits. Regardless of the user edits, the weir coefficient remained unchaged, reverting to the default(s).<\/p>\n\n\n\n Improved subscription license key management.<\/p>\n\n\n\n Correction to the graphics in reports when printed to a PDF file using Microsoft PDF printer driver. The Hydrograph and Rainfall IDF Curve plots will no longer be filled with a solid color, rather will be transparent.<\/p>\n\n\n\n A new task has been added\u2026 Groundwater<\/a>. This task is dedicated to retention pond recovery analysis using the Simplified Analytical Method per the St. Johns River Water Management District (SJRWMD) in the state of Florida. It allows you to calculate the recovery time of both unsaturated and saturated lateral infiltration for water quality retention ponds that are influenced by a shallow sandy aquifer.<\/p>\n\n\n\n 1. You’ll now have the option to utilize the Weighted Volume method, as well as the Weighted CN method when employing Composite CNs. Learn More<\/a>.<\/p>\n\n\n\n 1. Security Update. Our software code is digitally signed and secured using the latest signature algorithm sha256RSA insuring that the software you download here is authentic and untampered with. This version simply updates our Microsoft Authenticode Code Signing Certificate and may require a couple of steps more than usual to update to this version.<\/span> Please see Getting Software Updates<\/a> for more information.<\/p>\n\n\n\n 1.

In addition to managing your license directly from the software, you will have the capability to deactivate license keys remotely through the \u201cMy Account\u201d portal (View Licenses -> Manage Sites). This will be very helpful recovering lost seats, e.g., when a PC is decommissioned without prior deactivation.<\/p>\n\n\n\n

Code signing certificates assure users that the code they’re downloading is genuine and hasn’t been tampered with. Code signing certificates are used for many types of Windows-based software and applications. From time-time we are required to update Hydrology Studio’s certificate(s). This update facilitates that.
During the update download you might be presented with the following Windows Defender screen. Please click “More info”. Then click [Run anyway]. The update will proceed.<\/p>\n\n\n\n![\"\"](\"https:\/\/learn.hydrologystudio.com\/studio-express\/wp-content\/uploads\/sites\/6\/2018\/05\/Install1.png\")
