Revision history for Neo4j::Driver
0.49 2024-04-15
- Issue a Perl warning if a broken Neo4j::Client version is detected. For Bolt
support installed from CPAN, Neo4j::Client 0.46 is currently recommended.
0.48 2024-04-10
- The cypher_params config option now allows 'v2' as a synonym for v2.
- Minor documentation updates.
0.47 2024-04-09
- Returning a Result object from a managed transaction function now issues
a warning that the Result may not be valid outside the function.
- Clarify in documentation that concurrent_tx is a legacy feature.
- Minor documentation fixes.
- Minor testing improvements.
0.46 2024-03-03
- Add support for byte array values via Bolt and Jolt (Neo4j::Types v2).
- Fix Record->get() to not require its argument to be created as number when
used as index, or created as string when used as field name.
- Add check to prevent the HTTP-only concurrent_tx feature from being used
with neo4j: URIs.
- Add check to prevent plugin() after session().
- Update the "experimental" warning in the plug-in API documentation.
- Calling list methods in scalar context is no longer experimental.
- Avoid crash of types-temporal.t on Win32.
0.45 2024-02-16
- The boolean values used in HTTP query results are no longer chosen
by the JSON coder. Perl core booleans are used on v5.36 and newer;
on older Perl versions, JSON::PP booleans are used. (GH #16)
0.44 2024-02-06
- Result->peek() is no longer experimental.
- Result->consume() is no longer experimental.
- Result->summary() is discouraged in favour of consume().

immediately when the last record is retrieved.
- Minor testing improvements.
0.43 2024-01-31
- Accept neo4j: URIs, converting them to bolt / http / https.
- Change default URI from http://localhost to neo4j://127.0.0.1.

- Calling element_id() on nodes and relationships from Neo4j version 4
and earlier issues a warning. It will not become fatal.
- New Neo4j::Driver::Types doc as an initial step towards Neo4j::Types v2.
0.40 2023-07-19
- Add documentation that calling element_id() on nodes and relationships
from Neo4j version 4 and earlier might change to become a fatal error.
0.39 2023-07-06
- The concurrent_tx option is no longer experimental (now defaults to off).

- Mitigate test failures on slow machines and on Perl v5.10
0.36 2023-02-05

available to plug-ins as a Neo4j::Error object. (GH #7)
0.35 2023-01-24

"Bolt error -1" and become unusable after a server-side statement
evaluation failure inside an explicit transaction.
