Version	Date	Changes and/or Fixes	Thanks To
1.0.0	01/02/2014	Original release of QuickSnap
1.0.1	25/02/2014	Fixed an issue with GEM where classes 3-402 to 3-407 were incorrectly classed as 3-403 to 3-408 Fixed an issue where Native Interactive Grouper would not accept age variable (because QuickSnap was always trying derive age from Birth Date, Episode Start Date even when Age had already been supplied)	Oliver Berry, Department of Health WA
1.0.2	27/02/2014	Fixed issue with Overnight Palliative Care where 3-106 was incorrectly classified as 3-105 due to incorrect use of <= where < should have been used.	Oliver Berry, Department of Health WA
1.0.3	24/03/02014	Added a column called 'RecordIdentifier' to the QuickSnap Native Format so that the output file of the batch group for QuickSnap Native Format contained identifiable records	Ting Wong, Global Health
1.0.4	28/04/2014	the Native Interactive Grouper now includes data items for Date of Birth, Start Date, End Date and Leave Days – which enables calculation of ‘Age’ and ‘Length of Stay’. This change makes the items accepted by the interactive grouper consistent with the items in the QuickSnap DSS File Format. The interpretation of ‘Provider Type’ had a problem where if none of the provider flags were ticked, the system was interpreting the episode as a ‘Multi-disciplinary’ rather than an error class. After the fix, if no provider flags are ticked, an error ‘Required data item was invalid,Provider Type Flags’ and the episode is grouped with the error class 3-906.	Debra Hinton, NSW Health
2.0.0	05/06/2015	Updated QuickSnap to support AN-SNAP Version 4, with both a Batch and an Interactive Grouper.
2.1.0	22/10/2015	Resolved a bug where in batch grouping, Rehab episodes will inherit the last valid Impairment Code when an Invalid or Missing Impairment Code is encountered Support for AROC v4 'Legacy' Impairment Codes: the full MeTEOR codeset is still supported, along with mappings for V3 impairment codes which were deprecated in V4. This enables grouping of Episodes extracted from AROC Online Services where the Impairment Code was originally supplied using AROCv3 Impairment Codes and have been mapped to V4. Added the Age Type variable as per the AN-SNAP v4 Manual: Age Type: is the primary determinant of Adult/Paediatric classification for Palliative Care and Rehabilitation: If Age Type = 9 (Not Specified): Age will be used to determine Age Type If Age Type = 1 (Paediatric): Age will be validated, Age must be <= 19 If Age Type = 2 (Adult): Age will be validated, Age must be >= 16 This change involves the addition of this data item to all file formats	Ning Ding, Independent Hospital Pricing Authority
2.1.5	01/11/2015	Added V3 impairment codes as acceptable AROC Impairment Codes Age calculation now based on Episode Admission Date (rather than Phase Start Date) for Palliative Care Length of Stay for Palliative Care phases still based on Phase Start and End Date (but that is immaterial since length of stay is not used in grouping) added Phase Start Date and Phase End Date to every file format, since Palliative Care now requires Episode Start and End Date made Diagnosis Array interpretation more flexible to support MeTEOR definition and IHPA's internal format for this item corrected calculation of FIM Motor for circumstances where Impairment Code Group was not provided or was invalid (as is always the case in GEM)	Debra Hinton, NSW Health
2.1.6	12/01/2016	Resolved an issue in Adult Admitted Rehabilitation where Impairment Group is Stroke, Weighted FIM Motor 19-35. Age = 67 previously was incorrectly grouped to 4AA6 (should be 4AA7).
2.1.7	12/04/2016	Resolved an issue in Adult Admitted Rehabilitation where Impairment Group is Reconditioning, Weighted FIM Motor 50-66, FIM Cognition 5-25 (4AR3), 26-35 (4AR2). Grouper was previously grouping on the criteria FIM Cognition 5-30 (4AR3), 31-35 (4AR2)
