Versioning is a process of tracking changes to a database or software over time, allowing users to understand how the database has evolved and to easily roll back changes if necessary. As changes are made to the UI/UX of the database, it will be documented here in the release notes and this will include a brief description of the change, and the date it was made. We also use GitHub as the version control system to manage changes to the database by our developers. This allows us to track changes over time, roll back changes if necessary, and collaborate with others on the database.
Portuguese language support has been added to the application. Users can now switch between English, Vietnamese, Serbian, Ukrainian, Russian, Uzbek, and Portuguese, making the platform more accessible and inclusive for Portuguese-speaking users.
Russian and Uzbek language support has been added to the application. Users can now switch between English, Vietnamese, Serbian, Ukrainian, Russian, and Uzbek, making the platform more accessible and inclusive for Russian- and Uzbek-speaking users. As part of this update, several language components were consolidated and a number of untranslated labels were fixed across all supported languages. The project form navigation has also been made more responsive, adapting its tab labels and action buttons to fit smaller laptop screens and zoomed-in browser windows.
Numeric inputs across Financial Calculations, Economic Calculations, Project Details, and General Assumptions now handle formatted pasted values more reliably. Money values use format-on-blur display with comma grouping, year and percentage fields avoid unwanted thousands separators, and cleared or invalid entries resolve safely without producing NaN values. Fill-forward behaviour has been preserved where intended, dirty state tracking has been tightened, macro-economic rates now round consistently without adding new bounds, and result/report calculations have been hardened against legacy non-finite values.
Project forms are now protected against accidental data loss. If the user moves away from a form with unsaved edits — stepping between sections, switching tabs or projects, or closing the browser tab — the application prompts you to save first, continue without saving, or stay on the page. Saving from the prompt validates and stores your work before taking you to your destination. Save feedback has also been improved, with a clear notification if a save does not complete.
Users can now clone an existing project directly from their projects list. The clone workflow creates a new project under the current user account - prefixed with the copied title with [clone]. Uploaded project documents are not copied across to the new project. General project action feedback has also been improved with clearer success and error notifications.
Locale-based language content has been added to all remaining info modals across the application forms. These components are now dynamically built from our shared key tree structure making future updates easier to maintain across all supported languages.
The Excel onboarding workflow is now available to general public users, extending the workbook-based project setup flow beyond internal access. This update improves upload validation with a broader set of workbook structure and field checks, refines in-workbook validation feedback so users receive clearer guidance while entering data, and fixes several QA-reported edge cases around workbook versioning, validation prompts, and large numeric year-value inputs.
This patch resolves two PDF report generation issues identified through QA. Benefit summary rendering now handles long labels and percentage values more predictably, and the report delivery path has been hardened against middleware ICO asset requests that could bypass auth context during browser-driven PDF loads.
The admin dashboard now loads data progressively by section for a faster experience. Unique project analytics have been rebuilt with deterministic grouping logic, with new supporting routes that explain how values are calculated. A high-quality unique projects card and review page have been added, and the public projects section now supports all projects from the general account.
Users can now generate a PDF report summarising a screened project directly from the Results view. The report consolidates project details, analysis assumptions, and a per-variant summary covering CAPEX, OPEX, operational revenue, top economic benefits, and financial and economic indicators, with total cost shown in the project currency alongside EUR, USD, and the local currency equivalent. This feature is currently in beta — feedback from users will guide refinements ahead of a wider release.
Projects now support a wider range of world currencies, giving users more flexibility in project setup and reporting. Country sorting has been added to the project list for easier navigation, and the suspense (loading) UI has been refined for a smoother experience while content is being fetched. This update also includes a number of small bug fixes throughout the application.
Project country support has been added to the application. Users can now select the country of the project they are working on, making the platform more accessible and inclusive for users. Our internal dashboard has also been updated to display public project information.
Ukrainian language support has been added to the application. Users can now switch between English, Vietnamese, Serbian, and Ukrainian, making the platform more accessible and inclusive for Ukrainian-speaking users. All major navigation elements and modules have full Ukrainian translations, with ongoing improvements for a seamless localized experience.
Introduced the Excel Workbook Onboarding module (Admin only while in development). This workflow allows users to download a constrained eCBA workbook for offline data entry and upload it for validation. The template includes built-in error guidance, and successful uploads automatically save the project and redirect users to the analysis dashboard.
Introduced the AI project analysis dashboard component to drive analytics on platform-level data. This enables our internal team to gather insights into project diversity across sectors and countries, track user growth, and provides a better understanding of results screening and sensitivity analysis usage.
Serbian language support has been added to the application. Users can now switch between English, Vietnamese, and Serbian, making the platform more accessible and inclusive for Serbian-speaking users. All major navigation elements and modules have full Serbian translations, with ongoing improvements for a seamless localized experience.
The application now supports native multi-language support, allowing users to view and interact with the application in their preferred language. The update includes a language templating module that enables new country onboarding. The language documents are server-side rendered for faster loading times and improved performance.
The application has been migrated to a new hosting environment and the deployment processes streamlined for improved stability, faster response times, and enhanced developer efficiency. Users should experience faster page loads and more consistent performance across the platform and screening process.
Updates allow users to model new variants based off existing variants through the newly added clone function. Additionally, variant state is persisted when entering Financial or Economic input series data. This provides users with more flexibility and control over their analysis, allow users to quickly build on existing variants and move through the modelling process.
This update introduces several improvements to the project payload component, extending its functionality for future development and additional modules to be added to the eCBA. Changes focused on data handling and consistency across the application that were lead by user feedback and testing.
Based on user feedback, we've enhanced our video walkthrough content by restructuring it into three focused segments for better user experience. The updated series includes: (1) 'Introduction to eCBA' providing an overview of the application, (2) 'The eCBA in Practice' guiding users through project setup and screening processes, and (3) 'Interpreting Your Results' helping users understand and analyze their screened variant outcomes. This segmented approach makes the learning process more manageable and allows users to easily find specific guidance when needed.
This patch addresses a bug in the Macro Economic section where cumulative inflation calculations were not updating correctly when sensitive variables like the reference period were modified in Project Details. The fix ensures accurate inflation calculations that properly reflect changes to project parameters, maintaining data consistency across the application.
This patch addresses an edge case in the document management system where project files weren't being properly cleaned up during project deletion. The fix ensures that all associated documents are now correctly removed when a project is deleted, preventing orphaned files and maintaining system integrity.
We're excited to introduce two major features to enhance the eCBA. Users can now attach and manage various document formats directly at the project level, enabling better project documentation and supporting justification of input values with source materials. Additionally, we've launched the beta version of our eCBA Assistant (currently available to admin users), an AI RAG helper designed to guide users through platform features and provide real-time support for completing project analyses. This intelligent assistant aims to enhance user understanding and efficiency across the platform.
This update brings improvements to our API based on user testing feedback, ensuring more reliable and efficient data processing. We've enhanced form controls in the General Assumptions section, providing users with greater flexibility and validation capabilities. Several bug fixes were implemented, particularly addressing issues with reference period modifications in the Economic Benefits module to ensure accurate calculations and data consistency.
This update introduced a helpful video tutorial, providing step-by-step guidance for new users. The Macro Economic component now features auto-completion for inflation and real wage inputs, streamlining data entry. We've also enhanced the Economic calculation route with improved user guidance and tooltips. Several bug fixes were implemented in error handling components to provide more accurate feedback and prevent edge-case issues.
The eCBA now supports the Sensitivity Analysis module, which allows users to assess the impact of changes in input values on the project's financial and economic feasibility. This module is accessible through the Analysis tab once a user has completed their project setup.
Two core dependencies were updated to take advantage of the latest improvements and security patches. Time to first paint was reduced on multiple routes. The update also included a series of UX improvements to help user value inputs and general error handling.
This update focused on user input improvements and bug fixes. Additional control was given to the user during financial and economic data input. Bug fixes and frontend improvements were made to our newly added Mechanistic Damage and Loss module, ensuring a smoother user experience.
