Major changes:

- Added a new diagram type `"interactive"`. Interactive diagrams are a HTML pages containing "crumble".
- Added `stim.Circuit.inverse`
- Added `stim.Circuit.with_inlined_feedback`

Diagram improvements:

- Detector slice diagrams now use colors that are more color-blind friendly
- Added new diagram type `detslice-with-ops-svg` which overlays operations over the detector slice diagram
- The `type` argument for `.diagram` methods is no longer keyword-only
- The `tick` argument for `.diagram` methods can now be set to a `range(start, end)`, producing a diagram containing each tick in the range as a sub-diagram
- Detector slice diagrams now prefer shapes that have mirror symmetry, when choosing how to draw a stabilizer
- Detector slice diagrams now switch to using bezier curves when stroking between colinear points, to disambiguate which points are vertices and which points are skipped
- Increased the initial size used for the 3d model viewer and the svg viewer
- Improved the initial camera position used by the 3d model viewer to better frame the model
- Increased the font sizes used for gates in SVG diagrams, so they better fill their boxes
- Detector slice diagrams can now be filtered by `stim.DemTarget` (to slice observables in addition to detectors, include observable targets in the filter)
- SVG diagrams now group elements, making them easier to touch up afterwards in image editors

Sinter improvements:

- Added `--postselected_detectors_predicate` to `sinter collect`, generalizing `--postselect_detectors_with_non_zero_4th_coord`
- It's now possible to specify custom decoders

- `sinter predict` can now be given `--metadata_func auto` instead of `--metadata_func "sinter.comma_separated_key_values(path)"`
- Added command line arguments to `sinter plot`:
- `--y_func`
- `--y_axis`
- The expression given to `--plot_args_func` now has access to several more values: `stat`, `stats`, `decoder`, metadata`, and `strong_id`.
- The `plot_args_func` argument of `sinter.plot` methods can now take a third argument, `stats`, the list of stats in the curve
- Discard rate diagrams now include more Y axis indicators
- `sinter combine` now sorts its output
- Added `--order preserve|metadata|error` option to `sinter combine`

Notable bug fixes:

- Fixed `stim.Circuit.flattened` not fusing all operations
- Fixed `stim.Circuit.without_noise` not fusing all operations
- Fixed `PAULI_CHANNEL_2` not being marked as targeting pairs of qubits
- Fixed sinter's internal python files not being marked as private, so they don't appear as autocomplete suggestions
- Fixed `stim.Circuit.detector_error_model` failing when errors affected more than 15 detectors (unless decompose_errors=True)
- Fixed `stim.Circuit.without_noise` not making independent copies of the operations (!)
- Fixed sinter only sampling using the first decoder given to it, instead of all decoders, when given multiple decoders

- Fixed a segfault and bad parsing logic in `stim.read_shot_data_file` (!). Fuzz tested the read/write methods against the python reference methods to avoid this happening again.

Notable dev changes:

- Fixed files being opened in text mode instead of binary mode, resulting in bad parsing/serialization on Windows due to \n bytes being turned into \r\n and vice versa.
- Templatized classes like `simd_word` so AVX and SSE code can coexist in the same binary
- Added `stim_python_bindings` cmake target
- The cmake build now uses file lists which can be regenerated using a script
- Added `dev/` directory for scripts
- File lists used by cmake are now generated automatically instead of maintained manually
- The polyfill simd_word that uses 64 bit words now only uses one word instead of two (reducing padding overhead)
- To allow supporting a larger variety of decoders, sinter no longer includes each decoder in its requirements. Decoders need to be installed separately to use them.
- Added `-fPIC` to `libstim` cmake target
- Sinter now passes most information via the disk instead of through the multiprocessing API. This reduced the workload on the manager and the startup costs of batches, but made it much more disk limited on high core count machines.
- The API reference no longer shows deprecated methods (these methods are still listed in the .pyi stubs file)
- All doc strings now wrap at 80 characters, and this is enforced by continuous integration.
- The command line reference documentation has been substantially improved (e.g. flag information now grouped with the command instead of separate)
- Added python 3.11 support and OSX ARM support to the set of prebuilt wheels
