 ## Versioning & Updates
 
-- **Current version: v0.1**  
-  This release contains 354 curated entries, covering 16 cancer types and 58 unique HLA alleles (MHC-I). All entries include experimental immunogenicity evidence. Peptide lengths range from 8–13 amino acids, with 9-mers being the most common.  
+- **Current version: v0.2**  
+  This release contains **257 curated positive neoantigen peptides**, covering **25 cancer types** and **46 unique HLA class I alleles**.  
+  All entries are experimentally validated for immunogenicity and include harmonized molecular features such as binding rank, stability, anchor mutation, and expression context.  
+  Peptide lengths range from **8–13 amino acids**, with **9-mers** remaining the most common.
 
 - **Update strategy**  
-  Future releases will expand coverage by adding new literature sources, additional mutation types, and molecular features not yet included in v0.1. Patient-level metadata will also be progressively enriched as more information becomes available.  
+  NDD v0.2 represents a focused, high-quality subset of experimentally confirmed positive neoantigens,  
+  refined to support transparent benchmarking and community collaboration.  
+  Future versions will expand by incorporating validated negatives, additional mutation types,  
+  and extended clinical metadata to enable comprehensive model training and evaluation.
 
 - **Changelog**  
-  All modifications and additions will be documented in `CHANGELOG.md`, including new data sources, field extensions, and corrections.  
+  All modifications, new fields, and updates are documented in `CHANGELOG.md`,  
+  including patient cohort adjustments and dataset schema consistency.
 
 - **Reproducibility**  
-  Historical versions of the dataset will remain available in the repository, allowing users to reproduce analyses and compare results across versions.  
+  Historical drafts prior to v0.2 have been deprecated and are no longer public,  
+  ensuring that analyses and benchmarks reference a single, consistent dataset release.
