 * Usage of functions neighbor, runningAccumulate, runningDifferenceStartingWithFirstValue, runningDifference deprecated (because it is error-prone). Proper window functions should be used instead. To enable them back, set allow_deprecated_error_prone_window_functions=1. [#63132](https://github.com/ClickHouse/ClickHouse/pull/63132) (Nikita Taranov).

 * In the new ClickHouse version, the functions geoDistance, greatCircleDistance, and greatCircleAngle will use 64-bit double precision floating point data type for internal calculations and return type if all the arguments are Float64. This closes #58476. In previous versions, the function always used Float32. You can switch to the old behavior by setting geo_distance_returns_float64_on_float64_arguments to false or setting compatibility to 24.2 or earlier. [#61848](https://github.com/ClickHouse/ClickHouse/pull/61848) (Alexey Milovidov).
 
 * Queries from system.columns will work faster if there is a large number of columns, but many databases or tables are not granted for SHOW TABLES. Note that in previous versions, if you grant SHOW COLUMNS to individual columns without granting SHOW TABLES to the corresponding tables, the system.columns table will show these columns, but in a new version, it will skip the table entirely. Remove trace log messages "Access granted" and "Access denied" that slowed down queries. [#63439](https://github.com/ClickHouse/ClickHouse/pull/63439) (Alexey Milovidov).
 
 * Fix crash in largestTriangleThreeBuckets. This changes the behaviour of this function and makes it to ignore NaNs in the series provided. Thus the resultset might differ from previous versions. [#62646](https://github.com/ClickHouse/ClickHouse/pull/62646) (Raúl Marín).
