v5.9.0

Diff since v5.8.2

Define the new interface functions AbstractMCMC.getstats and AbstractMCMC.requires_unconstrained_space. Both used to be part of Turing's external sampler interface; they are now shifted here to allow for samplers to depend only on AbstractMCMC and not Turing.

Merged pull requests:

• Add AbstractMCMC.getstats and AbstractMCMC.requires_unconstrained_space (#182) (@penelopeysm)

Closed issues:

• Allow multiple callbacks (#80)
• Correct syntax for chainscat and chainsstack (#122)
• CI fails on 1.12 (#181)

v5.8.2

AbstractMCMC v5.8.2

Diff since v5.8.1

The num_warmup sampling keyword argument is now passed through to AbstractMCMC.step_warmup. This is useful because some warmup procedures (e.g. in HMC) may have different behaviour depending on whether it is the first warmup step or last warmup step.

Merged pull requests:

• Pass num_warmup as kwarg to step_warmup (#178) (@penelopeysm)
• Add a link to Turing docs (#179) (@penelopeysm)

When performing multiple-chain sampling (with MCMCSerial, MCMCThreads, or MCMCDistributed), an additional keyword argument chain_number is now passed as a keyword argument to callback functions. Its value runs from 1 to nchains.

Merged pull requests:

• Improve docstrings for MCMCThreads, MCMCDistributed, and MCMCSerial with usage examples (#171) (@Copilot)
• Add chain_number keyword argument when performing multi-chain sampling (#174) (@penelopeysm)

Closed issues:

• Unhelpfull docstring for MCMCThreads (#105)
