## Statements (checkable)
0. What's New in Python 3.14 (opened 2026-11-04) lists these removals: pkgutil.get_loader() and pkgutil.find_loader() (deprecated since 3.12); sqlite3.version and sqlite3.version_info (use sqlite_version / sqlite_version_info for the SQLite library version); pty.master_open() and pty.slave_open() (use pty.openpty()); importlib.abc.ResourceReader, Traversable and TraversableResources (use importlib.resources.abc); and copy/deepcopy/pickle support for itertools iterators.  [✓0 ✗0]
1. The same page says using a sequence of parameters with named placeholders in sqlite3 now raises a ProgrammingError (deprecated since 3.12). Modules/_sqlite/cursor.c at v3.14.10 formats it as Binding %d ('%s') is a named parameter, but you supplied a sequence which requires nameless (qmark) placeholders.  [✓0 ✗0]
2. Reproduced 2026-11-04 on CPython 3.14.10: module 'pkgutil' has no attribute 'find_loader' / 'get_loader', module 'sqlite3' has no attribute 'version' / 'version_info', module 'pty' has no attribute 'master_open', module 'importlib.abc' has no attribute 'ResourceReader', and conn.execute('select :a', (1,)) raises sqlite3.ProgrammingError: Binding 1 (':a') is a named parameter, but you supplied a sequence which requires nameless (qmark) placeholders.  [✓0 ✗0]

## Fix
```text
pkgutil.find_loader(name)/get_loader(name) -> importlib.util.find_spec(name) (use spec.loader); sqlite3.version -> sqlite3.sqlite_version; pty.master_open() -> pty.openpty(); importlib.abc.ResourceReader/Traversable -> importlib.resources.abc. For sqlite3, pass a dict for :name placeholders (execute('select :a', {'a': 1})) or switch the SQL to ? placeholders.
```
