+## 11.0.0 (02/20/2026)
+### New Features
+* Added `CompactionOptionsFIFO::max_data_files_size` to support FIFO compaction trimming based on combined SST and blob file sizes. Added `CompactionOptionsFIFO::use_kv_ratio_compaction` to enable a capacity-derived intra-L0 compaction strategy optimized for BlobDB workloads, producing uniform-sized compacted files for predictable FIFO trimming.
+* Include interpolation search as an alternative to binary search, which typically performs better when keys are uniformly distributed. This is exposed as a new table option `index_block_search_type`. The default is `binary_search`.
+
+### Public API Changes
+* Added new virtual methods `AbortAllCompactions()` and `ResumeAllCompactions()` to the `DB` class. Added new `Status::SubCode::kCompactionAborted` to indicate a compaction was aborted. Added `Status::IsCompactionAborted()` helper method to check if a status represents an aborted compaction.
+* Drop support for reading (and writing) SST files using `BlockBasedTableOptions.format_version` < 2, which hasn't been the default format for about 10 years. An upgrade path is still possible with full compaction using a RocksDB version >= 4.6.0 and < 11.0.0 and then using the newer version.
+* Remove deprecated raw `DB*` variants of `DB::Open` and related functions. Some other minor public APIs were updated as a result
+* Remove deprecated `DB::MaxMemCompactionLevel()`
+* Remove useless option `CompressedSecondaryCacheOptions::compress_format_version`
+* Remove deprecated DB option `skip_checking_sst_file_sizes_on_db_open`. The option was deprecated in 10.5.0 and has been a no-op since then. File size validation is now always performed in parallel during DB open.
+* Remove deprecated `SliceTransform::InRange()` virtual method and the `in_range` callback parameter from `rocksdb_slicetransform_create()` in the C API. `InRange()` was never called by RocksDB and existed only for backward compatibility.
+* Remove deprecated, unused APIs and options: `ReadOptions::managed` and `ColumnFamilyOptions::snap_refresh_nanos`. Corresponding C and Java APIs are also removed.
+* Remove deprecated `SstFileWriter::Add()` method (use `Put()` instead) and the deprecated `skip_filters` parameter from `SstFileWriter` constructors (use `BlockBasedTableOptions::filter_policy` set to `nullptr` to skip filter generation instead).
+
+### Behavior Changes
+* Change the default value of `CompactionOptionsUniversal::reduce_file_locking` from `false` to `true` to improve write stall and reduce read regression
+
+### Bug Fixes
+* Fix longstanding failures that can arise from reading and/or compacting old DB dirs with range deletions (likely from version < 5.19.0) in many newer versions.
+* Fix a bug where WritePrepared/WriteUnprepared TransactionDB with two_write_queues=true could experience "sequence number going backwards" corruption during recovery from a background error, due to allocated-but-not-published sequence numbers not being synced before creating new WAL files.
+
 ## 10.11.0 (01/23/2026)
 ### Public API Changes
 * New SetOptions API that allows setting options for multiple CFs, avoiding the need to reserialize OPTIONS file for each CF
