2025-02-13 Release#
Nonlinear Solver: Some Problems Delayed#
On 2025-02-10, some problems submitted to the Nonlinear solver were stuck in pending from approximately 04:03 AM to 09:51 AM Pacific time, at which time they were processed.
2024-12-11 Release#
Some Customers Could Not Log In to the Leap Service#
From 2024-12-03 at 1:00 PM Pacific time to 2024-12-05 at 5:52 PM, some customers could not log in to the Leap service; API access was unaffected.
2024-12-05 Release#
2024-11-28 Release#
Advantage_system4.1: Temporarily Degraded Solution Quality#
The Leap service’s Advantage_system4.1
QPU solver’s performance was
degraded on 2024-11-27 from 2:54 PM to 3:14 PM Pacific time. Affected users
have been contacted by D‑Wave.
2024-11-27 Release#
Advantage_system4.1: Temporarily Degraded Solution Quality#
The Leap service’s Advantage_system4.1
QPU solver’s performance was
degraded on 2024-11-23 from 5:50 PM to 6:26 PM Pacific time. Affected users
have been contacted by D‑Wave.
2024-10-28 Release#
QPU Solvers: Solution Quality for Fast Anneal Degraded#
Due to a software issue, performance of the fast-anneal feature on QPU solvers in the Leap service was degraded from 2024-10-02 to 2024-10-28. Affected users have been contacted by D‑Wave.
2024-10-21 Release#
Certain Problems Submitted to QPU Solvers Failed with HTTP 403#
Certain problems submitted to QPU solvers failed with the 403 Forbidden
HTTP status code. This issue was due to overzealous firewall rules
in the Leap service.
Compression on problem upload for QPU solvers, which is only available for Ocean SDK version 8 or greater and is enabled by default, made this issue more likely to occur.
2024-10-02 Release#
Nonlinear-Program Solver Did Not Reject Invalid Models#
The dwave-optimization
package version 0.3.0 or earlier allowed models that attempted to access
an array outside the array’s index range. From 2024-09-18 to 2024-10-02,
the nonlinear-program solver, hybrid_nonlinear_program_version1
,
did not properly reject problems with such models.
Affected users have been contacted by D‑Wave.
Advantage_system4.1: Temporarily Degraded Solution Quality#
The Leap service’s Advantage_system4.1
QPU solver’s performance was
degraded from 2024-09-24 at 11:41 PM Pacific time to 12:12 AM the next
morning. Affected users have been contacted by D‑Wave.
Solver Parameters and Properties Were Not Displayed for Some Users on the Dashboard#
For some users, clicking a solver in the Solvers section on the dashboard did not display the solver’s properties and parameters; instead, some text that included N/A was displayed.
2024-08-07 Release#
Error Received When Failing to Join Project#
When invited to join a project, a very small number of existing Leap service users received an error when clicking the email’s project acceptance link. Affected users have been contacted by D‑Wave.
2024-07-26 Release#
Advantage_system5.4: Degraded Solution Quality#
A small number of problems submitted to the Advantage_system5.4
solver
from 2024-07-10 to 2024-07-24 may have experienced degraded solution quality.
Affected users have been contacted by D‑Wave.
2024-07-16 Release#
Retrieving SAPI Tokens via the Leap Service’s API Failed#
From 2024-07-10 to 2024-07-16, attempting to retrieve a SAPI token via the Leap service’s API (for example, while configuring access to solvers in the Leap service from a Codespace) failed with an HTTP 404 error.
2024-07-10 Release#
Leap Admin: Global Search on Members Could Have Failed#
When an organization administrator typed a user’s name in the global-search bar and then clicked on a result, an HTTP 404 error was displayed instead of the user profile.
Leap Admin’s “Export to JSON” Did Not Download Sample Sets#
Some Leap service administrators may have received an error when attempting to export a solver’s returned sample set to JSON format.
2024-06-12 Release#
Advantage2_prototype2.3: Performance Temporarily Degraded#
The Advantage2_prototype2.3
solver’s performance was degraded from
2024-06-03 at 2:45 PM Pacific time to 8:05 AM the next morning. Problems
submitted using the fast-anneal protocol with anneals faster than 300 ns were
affected.
2024-05-15 Release#
Some Administrators Could Not Access Leap Admin#
From 2024-05-01 to 2024-05-02, some administrators were automatically logged out of their Leap service accounts when attempting to access Leap Admin.
2024-05-08 Release#
Advantage2_prototype2.3 Solver: Some Submissions May Have Had Degraded Solution Quality#
From 2024-05-01 to 2024-05-08, some problems submitted to the
Advantage2_prototype2.3
solver might have experienced a small degradation
in solution quality resulting from a now-corrected, minor shift
in the inductance of about 7% of the processor’s qubits.
For more information, contact D‑Wave Customer Support.
2024-05-01 Release#
Older Codespaces May Have Required Rebuild#
Due to a backwards-incompatible upgrade to the Solver API introduced on March
20, 2024, upgrading the
Ocean SDK
to version 6.9.0 or later was recommended if planning to use
the dwave auth login
CLI command.
Codespaces created from a D‑Wave GitHub repository before February 26, 2024, requiring reauthorization in the Leap service may have encountered an issue when attempting to log back into an existing Codespace after logging out. This issue could be resolved by launching the Codespace and running the following command in the VS Code command palette to rebuild the workspace with the latest Ocean SDK:
Codespaces: Full Rebuild Container
Advantage2_prototype2.3 Solver: Unstable Behavior at Short Fast-Anneal Times#
For the Advantage2_prototype2.3
solver, unstable behavior occurs when
fast-anneal times are below about 5 ns;
however, this unstable behavior has no effect on problem submissions
because the lower limit for anneal time, as returned by the fast_anneal_time_range
solver property, is now 5 ns.
2024-04-18 Release#
Could Not Retrieve a SAPI Token via the Leap Service’s API#
Due to an issue affecting OAuth 2.0 access to some of the Leap service’s API endpoints, OAuth clients were unable to fetch SAPI tokens or the list of projects from the Leap service.
The issue manifested in the Ocean CLI when configuring access to solvers
in the Leap service, for example when running
dwave config create --auto-token
or dwave leap project token
.
You may have encountered this issue in your
GitHub Codespace with the Ocean SDK installed. For example,
when running dwave auth login --oob && dwave config create --auto-token
,
the Ocean software’s CLI authorization command suggested for
D-Wave examples
opened in your GitHub Codespace, failed with error message
Failed to fetch SAPI token from Leap API.
2024-04-17 Release#
Sometimes Access Renewal Dates Were Outdated#
If a project’s Anniversary Date changed, sometimes the Access Renewal date as shown on the dashboard was not updated to the project’s new Anniversary Date.
