-What's New in 1.11
-------------------
-
-.. important:: Upgrade to Version 1.11.9 or Later
-
- Versions 1.11.0 through 1.11.2 of the driver have been retracted because
- of a bug that could cause undefined behavior when reading the ``Raw`` field
- on database error types, such as ``CommandError`` and
- ``WriteException``.
-
- Version 1.11.8 of the driver has been retracted because
- it incorrectly contains changes intended for 1.12.1.
-
- Upgrade to version 1.11.9 or later if you are using a retracted
- version of the driver.
-
-New features of the 1.11 Go driver release include:
-
-- Removal of support for MongoDB versions 3.5 and older.
-
-- Removal of support for Go versions 1.12 and older.
-
-- Improvements to ``Timeout`` API and behavior, including:
-
- - Modified retry logic for greater application resiliency.
-
- - Extended ``mongo.IsTimeout`` error helper to catch more timeout errors.
-
- - New GridFS methods that take contexts instead of using ``SetReadDeadline``
- and ``SetWriteDeadline``.
-
-- Reduced memory allocations during operation execution.
-
-- Fix for SRV polling bug that prevented changes in SRV records when the
- associated MongoDB connection string included a username and password.
-
-- Support for :abbr:`GCP (Google Cloud Platform)` service accounts when using
- Google Cloud Key Management Services.
-
-- Improvements to server-side resource cleanup when using the ``Cursor.All`` and
- ``Session.WithTransaction`` functions.
-
-- ``SERVICE_HOST`` Kerberos authentication parameter specification enabled with
- the ``authMechanismProperties`` connection string option.
-
-- Corrected output from the ``bson.Raw.String()`` method to Extended JSON
- type for timestamps when the BSON document contains a UTC Timestamp
- field.
-
-- Resolution of conflicts when retrying reads with read concern
- ``"available"`` or ``"linearizable"``.

- decoding empty types.
-
-- Support for encoding atypical map key types for data that can be unmarshalled
- into a textual representation of itself.
-
