Vadym BardaandGitHub 55f922cf2f langgraph: release 0.3.23 (#4141) 2025-04-02 09:50:18 -04:00
Nuno Campos 6efeefe424 Maintain checkpoint LATEST_VERSION constant in langgraph lib 
- This should be controlled by the langgraph version, not the version of langgraph-checkpoint installed

Nuno Campos 94fa46f9fa Avoid creating checkpoint unless we're saving it 
- When checkpointing is disabled don't call create_checkpoint in PregelLoop
- In local_read apply writes directly to copies of updated channels
- Add BaseChannel.copy() method to create channel copies with less overhead
 2025-03-31 18:37:13 -07:00
Nuno Campos fd64ada9de Avoid raise-catch strategy in BaseChannel.checkpoint() 
- This mirrors the work done earlier on BaseChannel.get()
- Comparing to a sentinel value is significantly faster than raising and catching an exception

Nuno Campos 067b99c789 Lazily create atomic counters in pregel scratchpad 
- many times these aren't actually used, so makes sense to delay creation until needed
 2025-03-31 15:19:53 -07:00
Nuno Campos e9e9a96a0d Reduce perf impact of pregel scratchpad creation 
- make scratchpad class frozen now that its members are never reassigned
- replace next(gen expr) with for-loop to avoid allocating generator objects
 2025-03-31 14:50:10 -07:00
Nuno Campos d30da72f6e Reduce the number of channels created for each node by 50% 
- Used to be 2 channels per node, it is now one per node, which is the minimum
- Now both hard edges, conditional edges, entrypoint and conditional entrypoint all use the same channel to trigger a node

Nuno CamposandGitHub 522caa643f In Python 3.12 or above, use asyncio eager task factory (#4055) 
- This is a performance improvement when calling async functions that do
not use await, as they are run immediately and never scheduled in the
loop

 		7021ce3742 patch: fix return type of Topic.update (#4029) 
This PR fixes the return type annotation of the `update` method from
`None` to `bool`, as the method returns a boolean value indicating
whether self.values has changed

 		87603d8a00 docs: add version admonitions for Interrupt and RetryPolicy (#3988) 
This pull request includes changes to add version admonitions to the
documentation and update the styling for these admonitions. The most
important changes include the addition of version information to the
documentation, updates to the CSS for version admonitions, and
modifications to the `mkdocs.yml` configuration file to include the new
stylesheets.
this should solve this #3991
