 ## 2024.01 Update
 
-1. Fixes in how gas in transactions on special accounts is accounted in block limit. Previously, gas was counted as usual, so to conduct elections that costs >30m gas block limit in masterchain was set to 37m gas. To lower the limit for safety reasons it is proposed to not count gas on special accounts. Besides `gas_max` is set to `special_gas_limit` for all types of transactions on special accounts. New behavior is activated through setting `gas_prices_v3` in `ConfigParam 20;`.
+1. Fixes in how gas in transactions on special accounts is accounted in block limit. Previously, gas was counted as usual, so to conduct elections that costs >30m gas block limit in masterchain was set to 37m gas. To lower the limit for safety reasons it is proposed to caunt gas on special accounts separately. Besides `gas_max` is set to `special_gas_limit` for all types of transactions on special accounts. New behavior is activated through setting `version >= 5` in `ConfigParam 8;`.
    * Besides update of config temporally increases gas limit on `EQD_v9j1rlsuHHw2FIhcsCFFSD367ldfDdCKcsNmNpIRzUlu` to `special_gas_limit`, see [details](https://t.me/tonstatus/88).
 2. Improvements in LS behavior
    * Improved detection of the state with all shards applied to decrease rate of `Block is not applied` error
    * Better error logs: `block not in db` and `block is not applied` separation
    * Fix error in proof generation for blocks after merge
+   * Fix most of `block is not applied` issues related to sending too recent block in Proofs
+   * LS now check external messages till `accept_message` (`set_gas`).
 3. Improvements in DHT work and storage, CellDb, config.json ammendment, peer misbehavior detection, validator session stats collection, emulator.
+4. Change in CTOS and XLOAD behavior activated through setting `version >= 5` in `ConfigParam 8;`:
+   * Loading "nested libraries" (i.e. a library cell that points to another library cell) throws an exception.
+   * Loading a library consumes gas for cell load only once (for the library cell), not twice (both for the library cell and the cell in the library).
+   * `XLOAD` now works differently. When it takes a library cell, it returns the cell that it points to. This allows loading "nested libraries", if needed.
 
-Besides the work of the core team, this update is based on the efforts of @XaBbl4 (peer misbehavior detection).
