改进记录包括：
Whats new in this release: * A key addition in this release is addition of App catalog. The app catalog incorporates registering applications, computational resources and flexible use of job management and data movement protocols. More Details: * [AIRAVATA-1125] - Application Catalog * [AIRAVATA-1067] - Allow file transfer from the gateway to the resource through Airavata * [AIRAVATA-1015] - Craft data models for application catalog * [AIRAVATA-1236] - Database design for Application Catalog * [AIRAVATA-1302] - Implement App catalog open-jpa layer and resource layer * [AIRAVATA-1303] - Start app-catalog database with app catalog thrift service starts * [AIRAVATA-1305] - Adding test cases to test app-catalog cpi API Changes: * AppCatalog API was added as described above. * No changes were made to previously release API methods. Improvement made in this release: * This release bundles a stable iteration of using Apache thrift as a framework to implement Airavata API. More Details: * [AIRAVATA-481] - GFac Sample * [AIRAVATA-958] - Integrate airavata credential store with GSISSH library in order to retrieve credentials * [AIRAVATA-989] - Clone a created experiment in Orchestrator to launch on different host * [AIRAVATA-1070] - Integrate the SSH file transfer between the gateway and resources to the Gfac * [AIRAVATA-1126] - Application Catalog Design * [AIRAVATA-1235] - No error type defined for a missing Project Issues fixed in this release: * Testing and bug fixing resulted in the following fixes. * [AIRAVATA-437] - Stdout and stderr files are read as string and will be problem if the file are big * [AIRAVATA-743] - Cleanup database sql scripts * [AIRAVATA-950] - Host parameters not saved in the database * [AIRAVATA-951] - Misleading error message in airavata server console when submitting a job to BR2 * [AIRAVATA-975] - Wrong exception given when certificate path is configured incorrectly * [AIRAVATA-1026] - GFacAPI logic to load input/output handlers is not working property * [AIRAVATA-1058] - Airavata 0.11 Source Build: Dependency Problems * [AIRAVATA-1085] - Update the Experiment Status * [AIRAVATA-1119] - JPARegistry tests are failing * [AIRAVATA-1310] - When entered gateway username and password user gets redirected to XSEDE user portal * [AIRAVATA-1338] - Cannot create Experiments using PHP Gateway * [AIRAVATA-1345] - Refresh button for Experiment Status page * [AIRAVATA-1347] - Cannot edit or view summery of experiments created with WRF application and its input files attached * [AIRAVATA-1348] - Cannot Save and Launch WRF experiment at the same time. It fails. Client Packages: * A key client side focus of this releases is to validate Airavata functionality with PHP clients. a PHP Reference Gateway is developed to exercise API functionality. * PHP command line samples also have been developed and tested against the API. * An initial version of the C++ SDK was also contributed but is not yet fully tested. More Details: * [AIRAVATA-1064] - Create php Samples using Airavata Thrift API Client SDKs * [AIRAVATA-1352] - In PGA gateway, include creation time in Experiment Summary Upgrade Instructions: * Airavata 0.13 should work with the previous 0.12 release. * Older releases will need to be manually updated. Beyond 1.0, Airavata will maintain backward compatibility within major releases. Known Issues: * Airavata 0.13 continous to be a stepping stone towards a stable 1.0 release. A known limitation is lack of a UI to register applications (using the app-catalog API). * XBaya and the workflow capabilities are being integrated into the new architecture and do not yet work with this release. A subsequent release (0.14) will bring back workflows into a functioning. Documentation: * This release was used as a tutorial to outreach apache airavata to science gateway developers. * Tutorial documentation - https://cwiki.apache.org/confluence/display/AIRAVATA/XSEDE+2014+Tutorial * [AIRAVATA-858] - Error data retrieval from the Airavata API * [AIRAVATA-1329] - Document Hands on tutorial material on PHP reference gateway * [AIRAVATA-583] - Improve content coordination across website and wiki
