# ClickHouse release 1.1.54292
## New features:
* Added the `pointInPolygon` function for working with coordinates on a coordinate plane.
* Added the `sumMap` aggregate function for calculating the sum of arrays, similar to `SummingMergeTree`.
* Added the `trunc` function. Improved performance of the rounding functions (`round`, `floor`, `ceil`, `roundToExp2`) and corrected the logic of how they work. Changed the logic of the `roundToExp2` function for fractions and negative numbers.
* The ClickHouse executable file is now less dependent on the libc version. The same ClickHouse executable file can run on a wide variety of Linux systems. Note: There is still a dependency when using compiled queries (with the setting `compile = 1`, which is not used by default).
* Reduced the time needed for dynamic compilation of queries.
## Bug fixes:
* Fixed an error that sometimes produced `part ... intersects previous part` messages and weakened replica consistency.
* Fixed an error that caused the server to lock up if ZooKeeper was unavailable during shutdown.
* Removed excessive logging when restoring replicas.
* Fixed an error in the UNION ALL implementation.
* Fixed an error in the concat function that occurred if the first column in a block has the Array type.
* Progress is now displayed correctly in the system.merges table.
