The current version is 1.12. I've tried bumping but the tests hang on me.
All tests run successfully (there are expected failures, of course). The test suite is *extremely* thorough. I think this is good for mathematical software. Each test runs rather quickly; their number is huge. For 1.12, all tests for python-3.10 and 3.11 took about 5 hours. Full success. So, I'm committing 1.12.
Note that when people say hang, they do tend to genuinely mean hang as in no progress/more output.
There are a lot of progress indicators. They run all the time. It does not hung. Done: commit 271be9ede6d74c0ce3e356ae7596413fe7782463
... for you. mgorny seems to think it hanged for him though.
I think he was too impatient :-)
I think there was a period of 10 (or maybe 15) minutes whan no new output appeared. I think this was in documentation tests: program fragments were extracted from all the documentation. After that, these fragments were run relatively quickly, to compare their respective outputs with what is written in the documentation. A very useful invention, by the way: it ensures that the documentation does not get iut of sync with the code.
