 # Ryujinx Changelog
 All updates to the Ryujinx official master build will be documented in this file
 
+## 1.0.6670 - 2021-02-21
+### Changed
+- PPTC & Pool Enhancements:
+  - Fixed memory instability / excessive memory spikes in some "heavy" games after loading/saving .cache files (fixes issue reported by users);
+  - Fixed limitation of loading/saving large .cache files (fixes issue reported by users);
+  - Reduced memory usage when loading/saving .cache files;
+  - Ptc.Load & Ptc.Save now use XXHash128, which is 10 times faster than MD5;
+  - Fixed redundant saving / log spamming of .info files (fixes issue reported by users);
+  - Added a simple PtcFormatter library for deserialization/serialization, which does not require reflection, in use at PtcJumpTable and PtcProfiler; improves maintainability and simplicity / readability of affected code.
+  - Improved handling of Pools (Slim) for PPTC, allowing to halve the number of pools in use and thus reducing memory usage and slightly increasing the translation speed (you save ~1 second every 1k translations (for a CPU with 4+4 cores); so for 30k translations you save ~30 seconds (for the same CPU));
+  - BitMap pools are now limited during use and disposed after use;
+  - Pools Limiter is now configurable.
