Cloud Customer Notes
Costpoint Cloud customers receive updates through Deltek’s managed quarterly release process. New features and enhancements are delivered as part of the Cloud update, and customers are encouraged to review these release notes together with Cloud-specific documentation in the Deltek Learning Hub (DLH) to understand feature availability and any configuration considerations unique to the Cloud environment.
Opt-In Features
Some features delivered in Costpoint are optional and may require enablement before they become available.

On-Premises Customer Notes
This section provides information specific to on-premises Costpoint customers, including release methodology updates, upgrade considerations, and guidance on applying and validating updates.
Updates to the New Costpoint Release Methodology for On-Premises Customers
This section summarizes updates to the Costpoint Quarterly Release methodology for on-premises customers, first introduced with Costpoint 8.2 (June 2023). This approach helps Deltek deliver features more frequently while maintaining quality and stability.
Deltek delivers Quarterly Releases (QRs) that include new features, defect fixes, and regulatory updates. Calendar Year End (CYE) updates are delivered separately and are compatible with the current year’s Q2 release and later (Q3 and Q4).
Costpoint 8.2 (Deltek’s Innovation Release) follows Deltek’s Product Lifecycle Phases (see Product Lifecycle Phase Descriptions). Each QR is in Active Support for 3 months, then Maintenance Support for 6 months, before moving to Sustaining Support.
Upgrade expectations (on-premises)
Apply at least two QRs each calendar year (you may skip one QR as part of your annual upgrade plan).
To receive CYE updates (W-2, 1099, payroll, and other regulatory updates), you must be on the current year’s Q2 release or higher.
Because Q1 moves to Sustaining Support in September under the 9-month policy, remaining current helps ensure access to support updates and critical hot fixes.
To help accelerate upgrades, customers are encouraged to use Deltek-provided or alternative test automation tools. Learn more here.
As part of the Quarterly Release transition, Costpoint version numbers will reflect the year and quarter of release starting with 2025 Q1 (for example, 2025.1, 2025.2, and so on). See Support Lifecycle: Deltek Costpoint Product Family for the full release listing.

Michigan Q2 2026 SUTA Electronic Filing: MiUI EFW2 Updates
This enhancement updates Michigan SUTA electronic filing to comply with Version 2 of the MiUI EFW2 file format. The update ensures that employee-level reporting aligns with the revised Employee Detail Record (RS) requirements, particularly for adjustment reason handling and out-of-state wages formatting.
Compared to version 1, version 2 introduces three related updates:
Reason or Adjustment Code (RS 344-345) defaulting logic: Blank Reason or Adjustment Codes now default to:
00 for original submissions
01 for adjustment submissions replacing the v1 behavior where blank adjustment records defaulted to 10 (Out of State Wages)
Explicit definition of Reason or Adjustment Code 00: The description of code 00 has been updated to explicitly state that it represents an original submission that does not include out-of-state wages.
Out of State Wages (RS 348-358) field formatting: If there are no out-of-state wages to report, the Out of State Wages field must contain exactly eleven (11) blank spaces.
Attention: For more information, see: MiUi EFW2 File Format Employer Reference Document.
Create Quarterly SUTA Tax File (PRPSMM)
Use this screen to generate the quarterly SUTA tax file for Michigan with the updated EFW2 Version 2 format.
The screen sets the File Layout to EFW2 and disables the field to prevent changes.
The Adjustment Reason Code field in the file was updated so that it will use 10 and not 00 if there are out-of-state wages.
When no out-of-state wages exist, the application will fill Out of State Wages field with exactly eleven blank spaces.
Informational messages display during processing when:
There are no QTD out-of-state wages but Adjustment Reason Code is 10.
There are QTD out-of-state wages but Adjustment Reason Code is not 10.
Manage SUTA Quarterly Reporting Data (PRMQRD)
The system uses the Adjustment Reason value from this screen when determining the correct RS 344-345 output for Michigan filings. The Adjustment Reason Description of 00 was updated from “Original submission” to “Original submission of a record that does not include out of state wages.”
This enhancement requires the following:

Vermont Q2 2026 SUTA Electronic Filing
This enhancement updates Vermont Quarterly SUTA electronic filing to align with the state’s current ICESA file layout requirements for the modernized UI system. It updates Vermont-specific processing on the Create Quarterly SUTA Tax File and Manage SUTA Tax File Data screens so you can generate files that match the revised state format and reporting rules. The update also changes how Vermont employer account numbers, total hours worked, business status indicators, and other file elements are reported.
For Vermont, some controls are now unavailable because the state no longer requires or accepts those values in the same way. This enhancement applies only when the filing state is Vermont.
Manage SUTA Tax File Data (PRMSMM)
The Manage SUTA Tax File Data screen now applies Vermont-specific behavior for fields that are no longer used in the updated Vermont ICESA file layout. When you select VT (Vermont) as the filing state, the screen:
Disables the Media Transmitter/Auth. No./Suffix Code/EFT controls.
No longer validates Media Transmitter/Auth. No./Suffix Code/EFT as numeric.
No longer reports the Media Transmitter/Auth. No./Suffix Code/EFT value in the Vermont Code A Authorization Code field.
Create Quarterly SUTA Tax File (PRPSMM)
The Create Quarterly SUTA Tax File screen now includes Vermont-specific updates that support the revised ICESA file layout and reporting requirements. When you select VT (Vermont) as the filing state, the screen:
Sets the default value of the Computer Manufacturer field to DELTEK.
Enables the Amended checkbox.
Updates the Business Status (Vermont) drop-down list under Other Filing Info with Vermont-specific filing options.
Uses the latest Vermont file layout which includes the following updates:
Code A 141-153 Original or Amended: Added field and source is the Amended checkbox
Code A 208-213 Authorization Code: No longer report the Media Transmitter/Auth. No./Suffix Code/EFT fields
Code A 243-250 File Creation Date: Renamed field name
Code E 173-179 VT Employer Account Number: Must be right -justified and zero-filled
Code S 155-161 VT Employer Account Number: Must be right -justified and zero-filled
Code S 235-238 Total Hours Worked: Now applies to all employees (previously hourly employees only)
Code S 239-244 Filler: No longer report the hourly wage, must be zero-filled
Code T 2-8 Total Number of Employees: Corrected data type to numeric
Code C 2-18 VT Employer Account Number: Must be right-justified and zero-filled
Code C 243-250 Unemployment Contribution Amount Due: Renamed field name
Code C 112 Employer no longer has employees/Discontinued operations in Vermont: Renamed field name, updated source
Code C 113 Out of Business: Renamed field name, updated source
Code C 114 Employer change in address or name: Renamed field name, updated source
Code C 115 Employer change in payroll service provider: Renamed field name, updated source

Purchasing >> Import Purchase Orders
Defect 2679752: When you updated purchase orders using the Import Purchase Orders preprocessor (AOPUTLPO), the approval date and approval user fields were inconsistently populated compared to updates made through the Manage Purchase Orders screen (POMMAIN). The preprocessor overwrote existing approval values on purchase order lines with data derived from the purchase order header, while the Manage Purchase Orders screen retained the original approval values. This discrepancy caused approval audit data to be overwritten during batch updates, impacting records with previously valid approval information.

Purchasing >> Manage Purchase Orders
Defect 2697021: When you entered the awarded quote on a purchase order line, a false-positive "different unit of measure" error displayed, even when the PO line's unit of measure matched the corresponding quote line's unit of measure. The error occurred only on quote lines with a unit of measure differing from the majority unit of measure across the quote's lines. Lines sharing the majority unit of measure accepted the awarded quote without error.
For Pick and Choose deployment: If you choose not to apply this hotfix, as a workaround, you can avoid entering the awarded quote on the purchase order line.
