Evaluate PyTango upgrade from 10.1.2 to newer version

[utkarshp1161]

Background

We currently have PyTango 10.1.2 installed. The following newer versions are available on PyPI:

Version	Date	Type
10.1.3	Feb 10, 2026	Patch
10.1.4	Mar 3, 2026	Patch
10.3.0rc1	May 22, 2026	Release candidate

Before deciding whether to upgrade, we should answer the following questions.

---

Questions

Functionality

• Do the newer versions introduce anything useful for our abstraction layer?
• Are there API changes that would make our code simpler or more ergonomic?
• Also keeping in mind LLM (agentic) Usage

Breaking Changes

• Do any versions introduce breaking changes to data structures or interfaces we rely on?
• Is there a migration guide we need to follow?

Dependencies

• Do newer versions require a cppTango upgrade? If so, what is the effort?

Testing

• Do newer versions change behaviour in DeviceTestContext or test utilities that would affect our test suite?
• Do we need to update mocks or fixtures?

Risk

• Is 10.3.0rc1 stable enough to track or pin for future adoption?
• What is the rollback plan if an upgrade breaks something?

What do you guys think on this?

[DomPTech]

I think migrating to 10.1.3 or 10.1.4 is low-risk for now. They appear to add minimal fixes and docs/build compatibility improvements with no obvious API changes.
We should consider 10.3.0rc1 more thoroughly as it looks like it introduces various binding and async changes. I'll take a closer look later.
