{{ $NEXT }}
- PERL-671 Update CRUD testing data files
v1.6.1 2017-01-10 09:26:56-05:00 America/New_York
[Bug fixes]
- PERL-711 Support authSource URI parameter
- PERL-712 Undefined reference to strerror_r on Windows
v1.6.0 2016-11-29 12:12:26-05:00 America/New_York
[*** Deprecations ***]
- PERL-643 No new deprecations, but deprecated methods now issue warnings
and a stack trace once per call-site.
- PERL-443 Database->collection_names takes an optional filter parameter.
- PERL-611 Add support for the BSON Decimal128 type, available in
MongoDB v3.3.8 or later. Adds a dependency on BSON::Decimal128 as the
type-wrapper for this type.
- PERL-620 Add support for GridFS files with custom file_id values.
- PERL-626 PERL-680 PERL-684 Add support for maxStalenessSeconds
configuration parameter, available for use with MongoDB v3.4.0 or later.
- PERL-627 Add support for sending write concern for all database
commands that allow it (varies based on server version). Exceptions
will be thrown if write concern is requested for a command and
the server version does not support it.
- PERL-635 Add support for collation option to CRUD and index building
methods, available in MongoDB v3.4.0 or later.
- PERL-649 Report driver information, system information, and
user-configured application name to server during connection handshake.
[Bug fixes]
- PERL-582 Fix some edge cases in URI parsing.
- PERL-630 ReadConcern level must always be lower-case when sent to
- PERL-632 Fix server selection bugs in the case of read preferences with
multiple tag-set entries.
- PERL-670 Make collection drop check for server error codes, not just
a magic text error string.
- PERL-685 Cached primary for server selection now expires based on
heartbeat frequency.

v1.4.5 2016-08-22 15:40:36-04:00 America/New_York
[Bug fixes]
- PERL-652 The deprecated legacy 'update' method had a bug that wouldn't
allow an empty replacement document (which destroys all fields except
for _id). While strange, this now works.
v1.4.4 2016-07-27 15:06:43-04:00 America/New_York
[Bug fixes]
- PERL-647 Authenticate always to topology type Single to ensure
auth happens for hidden or uninitialized replica set members.
v1.4.3 2016-07-18 16:05:16-04:00 America/New_York
[Bug fixes]
- PERL-636 Fix application of read preference to mongos
- PERL-638 Fix application of query modifiers for MongoDB server 3.2+
v1.4.2 2016-06-14 09:30:05-04:00 America/New_York
[Bug fixes]
- PERL-622 Fixed GridFSBucket uploads when Class::XSAccessor
is not installed. NOTE: Class::XSAccessor is currently listed
as a requirement for MongoDB. This and PERL-621 lay the
groundwork for making the driver optionally pure-Perl.
v1.4.1 2016-05-17 13:34:58-04:00 America/New_York
[Bug fixes]
- PERL-621 Fixed GridFSBucket uploads when Class::XSAccessor (an
optional dependency for Moo) is not installed.
- Consolidated v1.3.x change notices into section v1.4.0
v1.4.0 2016-05-10 16:59:16-04:00 America/New_York
[*** Deprecations ***]
- The MongoDB::GridFS and MongoDB::GridFS::File classes are deprecated
in favor of the MongoDB::GridFSBucket and related classes. It will
be removed in a future major release.
- PERL-610 Adds support for maxTimeMS for parallel_scan (available in
MongoDB 3.4).
- Adds MongoDB::GridFSBucket class, which implements the new
driver-standard GridFS API. Also included are classes to emulate file
handles for uploads and downloads, making GridFS operations more
composable with existing Perl libraries.
[Bug fixes]
- PERL-619 Fixed BSON memory leak when throwing exceptions during
encoding or decoding.
- Invalid BSON documents (e.g. invalid length, not null-terminated) were
silently ignored; the driver now correctly throws an error.
- bypassDocumentValidation is now sent as a boolean.
- Fixed index creation examples.
- Fixed some typos and broken POD links.
[~ Internal changes ~]
- 'insert_one' with write concern {w:0} is sent via the legacy OP_INSERT
wire protocol for reduced latency.
- Optimized some query/command execution paths.
v1.3.4 2016-04-27 11:06:55-04:00 America/New_York (TRIAL RELEASE)
v1.3.3 2016-03-08 15:10:33-05:00 America/New_York (TRIAL RELEASE)
v1.3.2 2016-01-26 16:44:09-05:00 America/New_York (TRIAL RELEASE)
v1.3.1 2015-12-23 12:03:47-05:00 America/New_York (TRIAL RELEASE)
v1.3.0 2015-12-18 12:21:09-05:00 America/New_York (TRIAL RELEASE)
v1.2.3 2016-03-08 15:15:36-05:00 America/New_York
- Fixed tests for v3.3.X MongoDB series
- Fixed method and attribute documentation in MongoDB::BSON::Regexp
v1.2.2 2016-01-26 15:33:30-05:00 America/New_York
[Bug fixes]
- PERL-602 Support legacy Cpanel::JSON::XS booleans (before 2.3404)
- PERL-604 Improve detection of stale primaries when a replica set
election protocol version is being upgraded/downgraded.
- Fix uninitialized 'inserted_count' in MongoDB::InsertManyResult
- Fixed broken link in POD for MongoDB::DataTypes
v1.2.1 2015-12-18 11:32:19-05:00 America/New_York
[Bug fixes]
- PERL-599 Fix bson/bson-error.c compilation problem on Win32
v1.2.0 2015-12-07 12:55:11-05:00 America/New_York
- PERL-561 Add support for bypassDocumentValidation option to relevant
CRUD methods.
- PERL-564 Add support for readConcern (for MongoDB 3.2 only).
- PERL-569 Add 'batch' method to QueryResult for retrieving a chunk of
results instead of just one (via 'next') or all.

MongoDB 3.2 servers.
- Add find_id method to MongoDB::Collection for easy retrieval of a
single document by _id.
- Add support for write concern find-and-modify-style methods (for
MongoDB 3.2 only)
[Bug fixes]
- PERL-493 Don't send writeConcern if it is not set; this allows the user
to get the default write concern set on the server.
- PERL-571 Add -D_GNU_SOURCE to ccflags if needed.
- PERL-597 Check findAndModify-type command results for
writeConcernErrors (for MongoDB 3.2 only).
- PERL-595 Change limit/batchSize behavior to match CRUD spec; most users
won't notice the difference, but generally speaking, when there is both
a limit and a batch size, under MongoDB 3.2, the batch size is
respected if it is smaller than the limit. Previously, in some cases,
the batch size was ignored and the limit used instead.
- PERL-570 Update MongoDB::Cursor::info documentation.
- Replace term 'slave' with 'secondary' in docs.
- Skip fsync test on inMemory storage engine.
[~ Internal changes ~]
- PERL-558 Implement fsyncUnlock as a command for MongoDB 3.2+.
- PERL-563 Implement find/getMore/killCursors as commands for MongoDB
- Verify that server replies are less than maxMessageSizeBytes.

[Bug fixes]
- Fixed BSON encoding tests for big-endian platforms.
v1.0.2 2015-10-14 15:26:30-04:00 America/New_York
[Bug fixes]
- PERL-198 Validate user-constructed MongoDB::OID objects; also
coerces to lower case for consistency with generated OIDs.
- PERL-495 Preserve fractional seconds when using dt_type 'raw'
- PERL-571 Include limits.h explicitly rather than relying on other
headers to load it.
- PERL-526 Detect stale primaries by election_id (only supported by
MongoDB 3.0 or later)

- Fix a failing test in the case where a user is running a
single-node replica set.
- PERL-532 Document loss of precision when serializing long doubles
- Noted that IPv6 support requires IO::Socket::IP (core since
Perl v5.20.0).
- PERL-579 Require at least version 0.25 of
[~ Internal changes ~]
- PERL-475 Optimize 'all' QueryResult method
v1.0.1 2015-09-22 12:55:08-04:00 America/New_York
[Bug fixes]
- PERL-567 Fixed a failing test in the case where a user is running a
replica set on the default port 27017.
- PERL-568 Fixed SYNOPSIS of
- Clarified some confusing sections of MongoDB::Tutorial and added
hyperlinks to documentation for methods used in the tutorial.
- Clarified some sections of MongoDB::Collection and MongoDB::Cursor
and added some hyperlinks.
v1.0.0 2015-09-21 16:15:04-04:00 America/New_York
[!!! Incompatible Changes !!!]
- The v1.0.0 driver includes numerous incompatible changes; users are
STRONGLY encouraged to read MongoDB::Upgrading for advice on upgrading
applications written for the 'v0' driver.
- PERL-221 The 'inflate_regexps' MongoDB::MongoClient option has been
removed. BSON regular expressions always decode to
MongoDB::BSON::Regexp objects. This ensure safety and consistency with
other drivers.
- PERL-330 The driver now uses pure-Perl networking; SSL and SASL now
implemented via optional CPAN modules IO::Socket::SSL and Authen::SASL.
- PERL-442 Connection string options have revised to match MongoClient
options; connection string options always take precedence over
MongoClient constructor arguments.
- PERL-470 The MongoDB::Cursor globals "slave_ok" and "timeout" no longer
have any effect and have been removed.
- PERL-471 The MongoDB::Cursor 'snapshot' method now requires a boolean
- PERL-505 When bulk inserting a document without an '_id' field, the _id
will be added during BSON encoding, but the original document will NOT
be changed. (This was the case for regular insertion in the v0.x
series, but not for the Bulk API.)
- PERL-519 The $MongoDB::BSON::use_binary global variable has been
removed. Binary data always decodes to MongoDB::BSON::Binary objects
(which now overload stringification). This ensures that binary data
will correctly round-trip.
- PERL-520 The $MongoDB::BSON::utf8_flag_on global variable has been
removed. BSON strings will always be decoded to Perl character strings.
This ensures that string data will correctly round-trip.
- PERL-523 Requires a replica set name explicitly to connect to a replica
set. Connecting to a single host is always in a 'direct' mode
- PERL-546 MongoDB::DBRef objects no longer have a 'fetch' method or
'client' attribute. This is consistent with the design of the MongoDB
drivers for other language. For the Perl driver, specifically, it
decouples the BSON model from the MongoClient model, eliminates a
circular reference, and avoid Perl memory bugs using weak references
under threads.
- MongoDB::MongoClient configuration options are now read-only and may
not be modified after client construction.
- The $MongoDB::BSON::looks_like_number and $MongoDB::BSON::char global
variables now ONLY have an effect at MongoDB::MongoClient construction.
Changing them later does not change BSON encoding. Both are deprecated
as well and should not be used in new code. Instead, the enhanced
MongoDB::BSON codec class has attributes that encapsulate these
- The 'dt_type' MongoDB::MongoClient option has been deprecated and made
read-only. It now only takes effect if C<MongoDB::MongoClient>
constructs a MongoDB::BSON codec object and is read-only so that any
code that relied on changing it after client construction will fail
rather that being silently ignored.
- The 'inflate_dbrefs' MongoDB::MongoClient option has been removed. By
default, dbrefs are always inflated to MongoDB::DBRef objects.
- The MongoDB::MongoClient 'read_preference' method is no longer a
mutator. It is now only an accessor for a MongoDB::ReadPreference
object constructed from 'read_preference_mode' and
- The legacy read preference constants in MongoDB::MongoClient have been
removed, as they are no longer are used with the new
MongoDB::ReadPreference class.
- The MongoDB::MongoClient 'authenticate' method has been removed;
credentials now must be passed via configuration options and
authentication is automatic on server connection.
- The MongoDB::Cursor class has been split. Actual result iteration is
done via a new MongoDB::QueryResult class.
- MongoDB::Error exception objects are now used consistently throughout
the driver, replacing other error mechanism and raw "die" calls.
- The MongoDB::WriteResult class was renamed to MongoDB::BulkWriteResult.
- The long-deprecated MongoDB::Connection class has been removed.
- Low-level client functions have been removed.
[*** Deprecations ***]
- PERL-398 The MongoDB::MongoClient 'timeout' and 'query_timeout' options
are deprecated in favor of new, more explicit 'connect_timeout_ms' and
'socket_timeout_ms' options.
- PERL-424 The MongoDB::Cursor 'count' method has been deprecated.
- PERL-464 The MongoDB::Database 'last_error' method has been deprecated.
- PERL-507 MongoDB::Collection 'get_collection' method is deprecated; it
implied sub-collections, which don't actually exist in MongoDB.
- PERL-511 The old CRUD method names for the MongoDB::Bulk API have been
deprecated in favor of names that match the new MongoDB::Collection
- PERL-516 The MongoDB::Collection index management methods have been
deprecated in favor of the new MongoDB::IndexView API.
- PERL-533 The MongoDB::Collection 'save' method has been deprecated.
- PERL-534 The MongoDB::Collection 'validate' method has been deprecated.
- PERL-559 The MongoDB::Database 'eval' method has been deprecated, as
the MongoDB server version 3.0 deprecated the '$eval' command.
- The MongoDB::MongoClient 'sasl' and 'sasl_mechanism' config options
have been deprecated in favor of the more generic 'auth_mechanism'
- Legacy MongoDB::Collection CRUD methods (insert, update, etc.) have
been deprecated in favor of new CRUD API methods.
- MongoDB::CommandResult changed the name of the accessor for the
document returned by the server to 'output' instead of 'result' for
clarity. The 'result' method is deprecated.
- As mentioned above, 'dt_type', '$MongoDB::BSON::looks_like_number' and
'$MongoDB::BSON::char' have been deprecated in addition to their other
behavior changes.
- PERL-93 Implemented awaitData cursor support.
- PERL-135 Added the ability to set write_concern at database and
collection level, rather than only in MongoDB::MongoClient.
- PERL-233 Implemented SSL certificate support via IO::Socket::SSL
- PERL-375 Added support for cursor options to the MongoDB::Collection
'find_one' method.
- PERL-378 Implemented the cross-driver Server Discovery and Monitoring
- PERL-379 Implemented the cross-driver Server Selection specification.
- PERL-406 Allowed count methods to work with query hints.
- PERL-408 Implemented SCRAM-SHA-1 and revised handshake for MongoDB 3.0
and later.
- PERL-413 Added max_time_ms as a MongoDB::MongoClient configuration
option to set a default for database and collection objects.
- PERL-422 Added support for specifying read preferences in the
connection string URI.
- PERL-465 Added support for arbitrary options on index creation.
- PERL-466 Added the ability to set read preference at the database and
collection level.
- PERL-486 Added 'has_modified_count' method to MongoDB::UpdateResult and
MongoDB::BulkWriteResult to ease detection of when that attribute is
supported by a server or not.
- PERL-490 Added 'list_collections' method to MongoDB::Database.
- PERL-500 Added 'topology_status' method to MongoDB::MongoClient.
- PERL-502 and PERL-503 Implemented new common driver CRUD API
specification in MongoDB::Collection.
- PERL-506 Added support for serializing/deserializing Time::Moment
- PERL-515 Added new MongoDB::IndexView API.
- PERL-554 Implemented 'server_selection_try_once' configuration option on
- Added an optional read preference argument to 'run_command'.
- Added 'db' and 'coll' methods as aliases for 'get_database' and
'get_collection' on MongoDB::MongoClient and MongoDB::Database,
- Added the 'get_namespace' method to MongoDB::MongoClient (with the
alias 'ns'), to get a MongoDB::Collection object directly from
a MongoDB::MongoClient object.
- Added a 'connect' class method to the MongoDB class for syntactic sugar
to create a client object.
- Added a 'with_codec' method to MongoDB::Collection for easier localized
changes to BSON codec attributes.
- Added a 'reconnect' method to MongoClient to handle reconnection after
a fork or thread spawn.
- Added support for correctly encoding boolean objects from JSON::XS,
Cpanel::JSON::XS, JSON::PP, JSON::Tiny and Mojo::JSON.
[Bug Fixes]
- PERL-146 Normalized server addresses to lower case.
- PERL-401 Fixed index creation to always have a non-zero write concern.
- PERL-409 Added missing declarations for MinGW on Windows.
- PERL-410 Fixed BSON encoding/decoding to detect and throw and error if
invalid UTF-8 is detected.
- PERL-429 Fixed read preference tag sets logic.
- PERL-435 Switched to http-style SSL certificate name validation.
- PERL-454 Prevented warnings when creating BSON datetimes at the epoch.
- PERL-477 Fixed list_indexes and list_collections when responses are too
big to fit in a single database response.
- PERL-480 Fixed GridFS bug: retrieving a GridFS file now throws an error
if no chunks exist instead of returning an empty string.
- PERL-489 Fixed fatal BSON encoding bug serializing references to
- PERL-531 Bulk update/replace documents would not validate properly when
$MongoDB::BSON::char was not '$'. While that functionality has moved
to the MongoDB::BSON codec instead of the global variable, all
update/replace documents (bulk and CRUD API) are now validated after
key munging.
- PERL-536 Fixed GridFS to stop throwing an error when a known empty file
has no chunks; errors will still be thrown if a non-empty file has no
- PERL-540 Fixed memory leak in DateTime::Tiny inflation.
- PERL-543 Fixed a bug serializing undef from Tie::IxHash objects.
- PERL-556 Fixed serialization of thread-shared variables.
- Fixed t/cursor.t for new explain format.
- Removed storage engine dependent code and tests.
- Fixed MSVC compilation: fix unused vars and statements before
declarations; removed unused, but problematic bcon.c and bcon.h; use
Perl memory alloc functions instead of malloc.
- Made conflicting 'multi' and 'multiple' update options fatal.
- Fixed use of slave_ok and $readPreference for communicating read
preferences to a mongos.
- Fixed t/database.t for change in server error message.
- Ensured topology type is correct whenever a server is marked

- Fixed bug in MongoDB::MongoClient::database_names error handling.
- Use of -Wall compiler flag during smoke testing has been restricted to
gcc compilers, only.
- Fixed encoding to raise an error if an array-reference document
contains duplicate keys.
- Stopped encoding scalar-ref objects as BSON BINARY type. (Throws an error
instead about an unhandled type.)
- Fixed incorrect configuration test for GCC atomic operations.
- Fixed bug numifying wtimeout in write concern serialization.
- Fixed BSON double tests on Perls with long-doubles enabled.
- Fixed t/gridfs to work around a bug in MongoDB 3.1.2.
- Fixed a number of XS memory leaks from non-mortalized variables during
BSON encoding.
- PERL-127 Integers that fit in 32-bits are now encoded as BSON Int32;
larger integers are encoded as BSON Int64; Math::BigInt objects are
always encoded as BSON Int64.
- PERL-331 The MongoDB::BSON package is now a full class, implementing a
BSON encoder-decoder (codec). It can be supplied as an attribute to
MongoDB::MongoClient, MongoDB::Database and MongoDB::Collection
- PERL-488 MongoDB::WriteConcern method 'is_safe' renamed to
- PERL-527 A database name is now optional for MongoDB::DBRef, which is
consistent with the DBRef specification.
- PERL-529 Connection string option keys are now parsed
- PERL-530 The driver now warns on unsupported connection options.
- PERL-550 DBRefs allow extra fields (for compatibility); this is not
recommended for new DBRefs.
- Renamed DocumentSizeError to a more general general DocumentError.
- MongoDB::Collection attributes that should not be set in the
constructor have been made private, but with public accessors for
backwards compatibility. Private attributes that are set in the
constructor (e.g. 'database') are now public.
- Failure to create indexes when constructing a GridFS object are ignored
rather than a fatal error.
- Calls to Carp::confess() or die() have been replaced with exceptions
from MongoDB::Error subclasses, typically MongoDB::UsageError.
- Generic MongoDB::Error exceptions have been replaced with subclasses
that have a specific, documented purpose, including:
MongoDB::AuthError, MongoDB::GridFSError, MongoDB::InternalError and
- Configuration options representing times have stricter validation such
that options that should be non-negative will raise exceptions when
given negative numbers.
- BSON code derived from libbson has been updated to libbson 1.1.7.
- Returns MongoDB::UnacknowledgedResult from unacknowledged writes (i.e.
{ w => 0 } write concern) instead of the corresponding result object
(i.e. MongoDB::InsertResult for inserts).
- Loads Authen::SCRAM::Client only on demand, as its Unicode module
dependencies are costly when not needed.
- MongoDB::QueryResult attributes have become private, as they are an
implementation detail and not intended for end-users to inspect.
- Aborts Makefile.PL on Windows before Vista/2008 for better error
message than subsequent compilation/test failures.
- Changes default connect_timeout_ms to 10,000.
- Credential details omitted from usage error messages.
- PERL-423 Improved documentation of cursor snapshot mode, as it doesn't
do what many people think it does.
- PERL-425 Documented deprecation of the 'drop_dups' option for index
- PERL-524 Updated legacy author emails in docs and metadata.
- Added contributors section to MongoDB main documentation based on git
commit logs.
- Added MongoDB::Upgrading document with changes from v0.x.
- Documented how to disable returning _id from queries.
- Rearranged Collection and Database documentation.
- Corrected errors in MongoDB::Cursor documentation.

for completeness.
- Added Class::XSAccessor, Moo and Type::Tiny::XS.
- Enforced minimum versions for configuration requirements.
- Moved DateTime::Tiny from a test_requires dependency to a
test_recommends dependency.
- Removed core modules File::Copy, File::Path and File::Spec from the
list of test dependencies.
- Removed Class::MOP::Class as an explicit dependency (still used
internally by Moose).
- Removed Data::Types and Data::Dump as test dependencies.
- Removed File::Slurp.
- Removed JSON module in favor of JSON::MaybeXS.
- Removed Moose, Syntax::Keyword::Junction and Throwable.
- Removed Test::Warn.
- Updated Path::Tiny minimum version to 0.054 (rather than unspecified).
- Updated IO::Socket requirement on Windows to 1.31.
- Updated Authen::SCRAM::Client minimum version to 0.003.
- PERL-467 Removed outdated MongoDB::Indexing document.
- PERL-497 The $MongoDB::BSON::use_boolean never worked; BSON boolean
values were always deserialized as objects. Rather than
"fix" this and break people's code, the option has been removed and
documented as such.
- The MongoDB::MongoClient 'auto_connect', 'auto_reconnect', and
'find_master' methods have been removed, as server discovery and
selection is now automatic.
- PERL-371 Added tests for parsing localhost:port.
- PERL-492 Implemented server selection tests.
- PERL-513 Added maxTimeMS tests for CRUD API methods.
- Changed text index test to use $text operator, not text command (which
was removed in MongoDB 3.0).
- Changed t/max_time_ms.t to skip unless $ENV{FAILPOINT_TESTING} is true.
- Reduced number of threads used in threads testing to avoid out of
memory errors on memory constrained systems.
[~ Internal changes ~]
- PERL-133 Implemented a test that client can connect to replica sets
without primary.
- PERL-259 Implemented write commands for MongoDB 2.6+ (i.e. doing writes
via database commands versus via the wire protocol with OP_INSERT,
OP_UPDATE, etc.).
- PERL-325 Updated vendored ppport.h to version 3.31.
- PERL-433 Updated listCollections to use command form on 3.0 servers.
- PERL-434 Updated listIndexes to use command form on 3.0 servers.
- PERL-436 Bumped maxWireProtocolVersion for 3.0 support.
- PERL-455 Changed to use connect timeout as the socket timeout for
topology scans.
- Implemented a 5 second "cooldown" period after a network error during
topology scanning during which new connection attempts will not be
made. This avoids excessive blocking in the driver when it's unlikely
that the server will be available right away.
- Removed unused vendored libyajl files.
- Refactored and reorganized perl-mongo.h and perl_mongo.c. Removed
unused functions and macros.
- Disabled many internal class type constraints and runtime assertions
unless the PERL_MONGO_WITH_ASSERTS environment variable is true.
- Changed use of 'strerror_s' to 'strerror' to attempt to get C/XS
linking on Windows XP.
- Changed all Moose classes to Moo classes for speed and to minimize the
deep dependency tree.
- Changed argument handling for CRUD API methods to stop coercing inputs
to Tie::IxHash. This makes them significantly faster.
- Optimized networking code paths substantially.
- Consolidated various constants to MongoDB::_Constants.
- Inlined and adapted the Throwable CPAN module to avoid deep
dependencies for MongoDB::Error.

[Bug Fixes]
- Fix auth connection issues (Olly Stephens)
- Fix driver creating duplicate connections when port isn't specified (Olly
- Fix authentication check on some versions of Perl (Olly Stephens)
0.45 - September 7, 2011
This is a recommended upgrade. There are no backwards-breaking changes, only
bug fixes and enhancements.
- Perl 5.8.4 and higher is now officially supported (5.8.7 was the previous
minimum version).
- Improved the way that connecting handles an interrupt signal. The driver
now continues to attempt connection for the remaining duration of the
timeout, instead of erroring out immediately.
[Bug Fixes]
- Fixed MaxKey and MinKey deserialization. Deserializing these types would seg
fault if they hadn't been serialized previously.
- Fixed Windows compilation (Taro Nishino)

0.44 - July 26, 2011
This is a recommended upgrade. There are no backwards-breaking changes, only
bug-fixes and enhancements.
- Added MongoDB::BSON::looks_like_number flag.
The Perl driver has always been coy about turning strings into numbers. If
you would like aggressive number parsing (if it looks like a number, send it
to the DB as a number), you can set MongoDB::BSON::looks_like_number to 1
(defaults to 0, the previous behavior). See the MongoDB::DataTypes pod for
more info.
- Tests should now clean up after themselves, leaving no test databases
[Bug Fixes]
- Setting a sort in the arguments to MongoDB::Collection::find is now passed
through correctly to the cursor.
- Fixed segmentation fault in array serialization: caused by specifying an _id
field on insert and using an array (not a hash or Tie::IxHash).
- Fixed segmentation fault in threading: if Mouse was used instead of Moose,
version 0.43 of the driver would segfault if multiple threads were used.
- MongoDB::Cursor now inherits the $Mongo::Cursor::slave_okay global setting,
as well as checking if slave_okay is set on the cursor instance.
- Fix GridFS functions to only ensure GridFS indexes on writes, allowing
GridFS API usage on slaves.
0.43 - May 31, 2011
This is a recommended upgrade. There are no backwards-breaking changes, only
bug-fixes and enhancements.
- Auto-detects max BSON size for inserts, which means documents larger than
4MB can now be inserted. See L<MongoDB::Connection/max_bson_size> for
- Added the L<MongoDB::Cursor/info> method, which returns meta information
about the results being returned.
