  - Uses statically sized ram buffers, independent of number of files
  - Posix-like api: open, close, read, write, seek, stat, etc
  - It can run on any NOR flash, not only SPI flash - theoretically also on embedded flash of a microprocessor
- - Multiple spiffs configurations can be run on same target - and even on same SPI flash device

  - Implements static wear leveling 
  - Built in file system consistency checks
  - Highly configurable
  
 What spiffs does not:
  - Presently, spiffs does not support directories. It produces a flat structure. Creating a file with path *tmp/myfile.txt* will create a file called *tmp/myfile.txt* instead of a *myfile.txt* under directory *tmp*. 
- - It is not a realtime stack. One write operation might take much longer than another.
+ - It is not a realtime stack. One write operation might last much longer than another.
  - Poor scalability. Spiffs is intended for small memory devices - the normal sizes for SPI flashes. Going beyond ~128Mbyte is probably a bad idea. This is a side effect of the design goal to use as little ram as possible.
  - Presently, it does not detect or handle bad blocks.
  - One configuration, one binary. There's no generic spiffs binary that handles all types of configurations.

 ## HISTORY
 
+### 0.3.6
+- Fix range bug in index memory mapping #98
+- Add index memory mapping #97
+- Optimize SPIFFS_read for large files #96
+- Add temporal cache for opening files #95
+- More robust gc #93 (thanks @dismirlian)
+- Fixed a double write of same data in certain cache situations
+- Fixed an open bug in READ_ONLY builds
+- File not visible in SPIFFS_readdir #90 (thanks @benpicco-tmp)
+- Cache load code cleanup #92 (thanks @niclash)
+- Fixed lock/unlock asymmetry #88 #87 (thanks @JackJefferson, @dpruessner)
+- Testframe updates
+
+New API functions:
+- `SPIFFS_ix_map` - map index meta data to memory for a file
+- `SPIFFS_ix_unmap` - unmaps index meta data for a file
+- `SPIFFS_ix_remap` - changes file offset for index metadata map
+- `SPIFFS_bytes_to_ix_map_entries` - utility, get length of needed vector for given amount of bytes
+- `SPIFFS_ix_map_entries_to_bytes` - utility, get number of bytes a vector can represent given length
+ 
+New config defines:
+- `SPIFFS_IX_MAP` - enable possibility to map index meta data to memory for reading faster 
+- `SPIFFS_TEMPORAL_FD_CACHE` - enable temporal cache for opening files faster
+- `SPIFFS_TEMPORAL_CACHE_HIT_SCORE` - for tuning the temporal cache
+
 ### 0.3.5
 - Fixed a bug in fs check
 - API returns actual error codes #84) (thanks @Nails)
