# Changelog
## 1.3.2
+ Support was improved for 14.0.0+.
+ `loader` was updated to reflect the latest official behaviors.
+ `ro` was updated to reflect the latest official behaviors.
+ A number of minor issues were fixed and improvements were made, including:
+ A memory leak was fixed in filesystem path management; this could cause a crash when launching games ~100 times, or when deleting/re-downloading games.
+ A bug was fixed that could cause threads to not see a newly signaled semaphore.
+ A number of minor inaccuracies were fixed in the updated FileSystem APIs.
+ General system stability improvements to enhance the user's experience.
## 1.3.1
+ Support was added for 14.1.0.
+ A number of minor under the hood improvements to accuracy were made to better reflect latest official system module behavior, particularly around FS apis.
