ForestDB v1.1 is released with some critical bug fixes and enhancements as described briefly below.

**Enhancements**
- Snapshot and rollback support without enabling a sequence tree. Previously, a sequence tree was enabled by default even if an application does not need to retrieve a KV item using its sequence number (e.g., fdb_get_byseq, fdb_get_metaonly_byseq) or iterate KV items by their sequence numbers (e.g., fdb_iterator_sequence_init). From v1.1, a sequence tree is disabled by default, but can be explicitly enabled by setting seqtree_opt to FDB_SEQTREE_USE.
- Support for non-mobile ARM linux platforms.

**Bug Fixes**
- [MB-18567](https://issues.couchbase.com/browse/MB-18567) Insert a dummy block into the buffer cache before accessing it
- [MB-18539](https://issues.couchbase.com/browse/MB-18539) Do not allow get_byoffset() for transaction marker block
- [MB-18158](https://issues.couchbase.com/browse/MB-18158) Use the old file's version info during the migration of KVS header info
- [MB-18712](https://issues.couchbase.com/browse/MB-18712) Fix to a bug on comparison between NULL and zero-filled chunk
