…ld host configure_dylibs.sh rewrote libodbcinst/libltdl references to @loader_path only for $(uname -m). the universal2 wheel bundles both libs/macos/arm64 and libs/macos/x86_64, so on the x86_64 release runner only x86_64 got fixed and the arm64 libmsodbcsql.18.dylib shipped pointing at /opt/homebrew/lib/libodbcinst.2.dylib. on a clean Apple Silicon mac that path is absent, so the driver only loads after `brew install unixodbc` (issue #656). this regressed in 1.8.0 (first release after the driver upgrade). 1.7.1 and earlier are clean. - loop configuration over both arm64 and x86_64 under libs/macos - re-fix the committed arm64 + x86_64 dylibs to @loader_path Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Sorry, something went wrong.
the arm64 libodbcinst.2.dylib and libltdl.7.dylib were already @loader_path (committed that way in #82), so the fix commit left them untouched. re-sign and commit them too so all six bundled macOS dylibs are the canonical output of a single configure_dylibs.sh run rather than a mix of #82-era and new signatures.

Pull request overview
Fixes a macOS wheel packaging regression where the universal2 wheel’s non-host architecture dylibs were not rewritten to use @loader_path, causing import mssql_python to fail on clean Apple Silicon machines without Homebrew unixodbc (issue #656).
Changes:
- Update configure_dylibs.sh to process both arm64 and x86_64 bundled dylib directories instead of only the build host architecture.
- Skip configuration for an architecture when its libs/macos/<arch>/lib directory is not present.
- Improve completion logging to be architecture-specific.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

mssql_python/pybind/configure_dylibs.sh
the "Initial configuration" otool block ran before the directory and file existence checks, so a missing arch directory would hit otool (which errors, and under set -e aborts the script) before reaching the graceful `continue`. move the checks above the otool calls: a missing arch dir now skips cleanly, and libmsodbcsql/libodbcinst are verified present before they are inspected (libltdl is already -f guarded).

Release mssql-python v1.11.0. [AB#46332](https://sqlclientdrivers.visualstudio.com/c6d89619-62de-46a0-8b46-70b92a84d85e/_workitems/edit/46332) ### Summary Version bump to 1.11.0. Updates `mssql_python/__init__.py`, `setup.py`, and `PyPI_Description.md`. Bundled `mssql_py_core` bumped from 0.1.5 to 0.1.6. #### Bug Fixes - **SSH-tunnel / in-process forwarder deadlock** — Release the GIL around blocking ODBC round-trips in the teardown path and `SQLDescribeParam`, so `close()` and parametrized queries with `None` values no longer deadlock in-process TCP forwarder setups (#604, issue #565). - **BINARY/VARBINARY NULL parameters in temp tables and table variables** — Proactively resolve unknown NULL parameter types before binding and emit actionable `setinputsizes()` guidance on `SQL_VARCHAR` fallback (#654, issue #627). - **Context manager transaction semantics** — `Connection.__exit__` now commits on clean exit and rolls back on exception when `autocommit=False`, instead of always rolling back (#639, issue #635). - **macOS Apple Silicon import failure** — `configure_dylibs.sh` rewrites bundled ODBC dylib dependencies to `@loader_path` for every architecture in the universal2 wheel, fixing `import mssql_python` on clean Apple Silicon machines (#661, issue #656). - **Service Principal bulk copy freeze** — Fixed a GIL-deadlock in the Rust core that froze bulk copy under `ActiveDirectoryServicePrincipal` auth; picked up via the `mssql_py_core` 0.1.6 bump (#666, issue #662). #### Version Bump - `mssql_python/__init__.py`: `__version__ = "1.11.0"` - `setup.py`: `version="1.11.0"` - `PyPI_Description.md`: `## What's new in v1.11.0` section refreshed.

Work Item / Issue Reference
Summary
on Apple Silicon the bundled ODBC driver in the macOS wheel points at an absolute Homebrew path (/opt/homebrew/lib/libodbcinst.2.dylib) instead of the copy shipped inside the package. on a clean machine that path is absent, so import mssql_python fails until brew install unixodbc creates it (#656).
root cause: configure_dylibs.sh rewrites the bundled dylib dependencies to @loader_path only for $(uname -m). the wheel is universal2 and ships both libs/macos/arm64 and libs/macos/x86_64, but the release runner is x86_64, so only the x86_64 driver got fixed. the arm64 driver shipped with its raw Homebrew path from the driver upgrade in #569. regressed in 1.8.0; 1.7.1 and earlier are clean.
fix:
verified both arches resolve libodbcinst/libltdl via @loader_path with no absolute paths remaining, and the fixed arm64 driver dlopens against its bundled siblings (and fails when isolated, so there is no system fallback).
