v1.7.1Compare Source
Patch notes 1.7.1
This is a micro patch release which fixes two bugs from the 1.7.0 release.
Bug fixes
v1.7.0Compare Source
CVXPY 1.7
This release is consistent with our semantic versioning guarantee. It comes packed with many new features, bug fixes, and performance improvements.
This version of CVXPY supports Python 3.9 through 3.13. While working on the next release, we continue to officially support CVXPY 1.6.
New GPU solvers
CVXPY begins supporting GPU solvers in this release. The following solvers are supported:
MPAX runs on a GPU device specified by the JAX environment. MPAX, cuOpt, and CuClarabel are new solver interfaces that can be used with CVXPY. SCS has a new backend based on cuDSS that can be used through the existing SCS interface.
Sparse array support
SciPy is deprecating the sparse matrix API in favor of sparse arrays. See the migration guide here.
CVXPY 1.7 supports the new sparse array API but continues to support the sparse matrix API for backwards compatibility.
Update on reshape order
In CVXPY 1.6, we began raising warnings for the default reshape order being Fortran ('F'),
which differs from NumPy's default order ('C'). We also mentioned that we would raise an error
if the order was not specified in CVXPY 1.7, and switch the default order to 'C' in CVXPY 1.8.
However, we have decided to postpone these changes to CVXPY 2.0, the next major release.
We believe that raising errors could break existing code and cause confusion among users.
We encourage users to continue explicitly specifying the order when using reshape, vec, and flatten atoms.

Special shoutout to @PTNobel for leading the integration of GPU solver interfaces into CVXPY.

CVXPY 1.6
This release is consistent with our semantic versioning guarantee. It comes packed with many new features, bug fixes, and performance improvements. This version of CVXPY supports Python 3.9 through 3.13. While working on the next release, we continue to officially support CVXPY 1.5.
Default reshape order warning
CVXPY's default order for array manipulation atoms such as reshape, vec and flatten, is Fortran ('F'). In this release CVXPY raises a warning when no explicit order is specified.
In version 1.7, we plan to raise an error if the order is not specified. Finally, in version 1.8, we will switch the default order from ('F') to ('C') to match NumPy's behavior.
Dropping ECOS dependency
In version 1.5, we changed our default solver from ECOS to Clarabel and announced that we would be removing ECOS as a dependency in 1.6. Despite some regressions in certain DQCP tests, we are moving forward with dropping ECOS in this release. If you are experiencing any issues with Clarabel we encourage you to try using SCS or add ECOS as a dependency to your project.
Features and bug fixes
- axis atoms like min, max and sum
- indexing
- elementwise operations

v1.5.4Compare Source
Patch notes (from #2628)
New backward support policy
This release will be the last one in the 1.5.x series.
We plan to no longer support cvxpy versions 1.5.x, where x<4, while we continue working on cvxpy 1.6.x
Version 1.5.4 will be the last supported version in the 1.5.x series. In the future, we might update 1.5.4 with backport bug fixes.
