[deps] Update channels-redis requirement from ~=4.1.0 to ~=4.2.0

[dependabot]

Updates the requirements on channels-redis to permit the latest version.

Changelog

Sourced from channels-redis's changelog.

4.2.0 (2024-01-12)

• Dropped support for end-of-life Python 3.7.

• Added support for Python 3.11 and 3.12.

• Upped the minimum version of redis-py to 4.6.

• Added CI testing against redis-py versions 4.6, 5, and the development branch.

• Added CI testing against Channels versions 3, 4, and the development branch.

4.1.0 (2023-03-28)

• Adjusted the way Redis connections are handled:

  • Connection handling is now shared between the two, core and pub-sub, layers.

  • Both layers now ensure that connections are closed when an event loop shuts down.

    In particular, redis-py 4.x requires that connections are manually closed. In 4.0 that wasn't done by the core layer, which led to warnings for people using async_to_sync(), without closing connections when updating from 3.x.

• Updated the minimum redis-py version to 4.5.3 because of a security release there. Note that this is not a security issue in channels-redis: installing an earlier version will still use the latest redis-py, but by bumping the dependency we make sure you'll get redis-py too, when you install the update here.

4.0.0 (2022-10-07)

Version 4.0.0 migrates the underlying Redis library from aioredis to redis-py. (aioredis was retired and moved into redis-py, which will host the ongoing development.)

Version 4.0.0 should be compatible with existing Channels 3 projects, as well as Channels 4 projects.

• Migrated from aioredis to redis-py. Specifying hosts as tuples is no longer supported. If hosts are specified as dicts, only the address key will be taken into account, i.e. a `password`` must be specified inline in the address.

• Added support for passing kwargs to sentinel connections.

• Updated dependencies and obsolete code.
