h2. Bugs Fixed Since Last Release

[EVS:GF#17670|https://gforge.nci.nih.gov/tracker/?func=detail&group_id=491&aid=17670&atid=1850] \- DAO is throwing a ClassCastException when attempting access MedDRA
In the DAO layer, there is code that holds, as a Collection, the terminology name and the security token. This particular Collection is a HashMap and there is an attempt to pull data from this HashMap by position. Unfortunately, HashMaps don't guarantee order. So, the there is a ClassCastException being thrown.&nbsp;

h2. Known Issues

[EVS:GF #15776|https://gforge.nci.nih.gov/tracker/index.php?func=detail&aid=15776&group_id=491&atid=1850] \- DLBWrapper.getSupportedCodingSchemes returns null
The DLBWrapper.getSupportedCodingSchemes returns null if any of the codingSchemes in the repository require secure access.
Currently the first vocabulary that it attempts to access is NCI Metathesaurus, which is secured. Remains to be seen
if it will return anything if the secured vocab is not first.

[EVS:GF #15817|https://gforge.nci.nih.gov/tracker/index.php?func=detail&aid=15817&group_id=491&atid=1850] \- Inconsistancy in the application of codingScheme name in DLBAdapter.
In the DLBAdapter you can do a .setVocabulary() to set the default codingScheme, version and tag that some queries of
the DLBAdapter will run against. However, this default codingScheme is not consistantly applied.
# Some methods in DLBAdapter allow you to pass in a codingSchemeName. Of these, some use the passed in codingSchemeName
with a null CodingSchemeVersionOrTag. Others use the passed in codingSchemeName plus the version or tag passed in as
the default in .setVocabulary.
# Some methods with no parameters automatically use the defaults. Others don't.

h2. Deferred/Deprecated Items

As the EVS Team looks toward the next major release of LexEVS (v5.0), we have begun to anticipate functionality that will naturally be absorbed by the LexBIG API. Those items have been classified as deprecated in our GForge tracking system. Additionally, those items that have not been evaluated has high priority items, have been deferred to the 5.0 release.These items/trackers can be viewed [here|https://gforge.nci.nih.gov/tracker/?atid=1850&group_id=491&func=browse].
