Update Nov-10-2022:

• Added EPICv2 manifest and annotations
Update Sep-03-2022:

• update to Ensembl manifests, mouse manifests and human anotation
• update to the documentation of column headers
Update Jun-15-2021:

• updated gene annotation to GENCODE v36 to be consistent with GDC. CGI column is updated to contain CGI only when CGIposition is not NA.
• updated mouse array gene model
Update Apr-14-2021:

• updated gene annotation to GENCODE v37
Update Jul-4-2020:

• More detailed annotation to SNP and channel-switching probes
Release Sep-9-2018:

• Added gene_HGNC column for gene symbols corrected for HGNC compatibility
• Updated SNP masking with dbSNP build 151
• All maskings were redone on hg19. Previously hg19 manifest file was "borrowing" hg38 maskings.
• CCS probes have shrunk in numbers based on AF filtering (>1%).
• See Updates Summary for more details.
Release Aug-8-2018:

• Fix to MASK_mapping, some mapping with NM>0 are now masked as well
• Addition of NM columns and gene annotation to the manifest file.
• Previously, masking of mapping issues were merged from hg19 and hg38. Now masking on hg19 and hg38 was re-built entirely independently. There is some small decrease in the number of masking due to this change and a small increase due to the added NM-based masking (included in MASK_mapping).
• See Updates Summary for more details.
Release Mar-4-2018

• Fix to hg19 decoy mapping inconsistency.
Release Jan-4-2018

• Updated strand information.
Release Nov-23-2017

• Changed to RDS from RData following R's recommendation.
• Update to missing value representation.
• Update to table headers.
• Added gene annotation in short forms.
• Added mapping to genome both including and excluding alt-chromosomes.
• Made consistent naming of columns with underscores.
Release Mar-13-2017
• fix to relative position in SNP masking of type-I probes.
