v0.45.0 (2025-03-25)

Highlights

Experimental msgspec IO

Taps and targets now support custom message writing and reading interfaces, and the new (experimental) msgspec-based encoding is available.
See the docs for more information.

Thanks to @BuzzCutNorman and @s7clarke10 for the thoughts and suggestions!

singerlib is now a public module

The low-level Singer library is now available as a public module and can be imported directly from singer_sdk.singerlib. If you're using the now deprecated _singerlib module, please update your code to use the new public module.

Singer Decimal string format

The x-singer.decimal JSON Schema extension is now supported by the SDK. Read the docs to learn how to use it with taps and targets.

@edgarrmondragon Do you know why Dependabot is not picking up the updated PyPI release (yet)? https://github.com/ReubenFrankel/tap-f1/actions/runs/14072314231/job/39408875511#step:3:204

[edgarrmondragon]

No idea 🤔.

https://pypi.org/pypi/singer-sdk/json does have the correct version under info, so I'm not sure why they're not picking it up.

I can't find any issue that seems relevant: https://github.com/dependabot/dependabot-core/issues. Maybe it's worth creating one.

[edgarrmondragon]

Ah, maybe
