+The Apache Arrow team is pleased to announce the 7.0.0 release. This covers
+over 3 months of development work and includes [**474 resolved issues**][1]
+from [**?? distinct contributors**][2]. See the Install Page to learn how to
+get the libraries for your platform.

+## Columnar Format Notes

+TBD
+
+## C++ notes
+
+A set of CMake presets has been added to ease building Arrow in a number
+of cases (ARROW-14678, ARROW-14714).
+
+The `arrow::BitUtil` namespace has been renamed to `arrow::bit_util`
+(ARROW-13494).
+
+Concatenation of union arrays is now supported (ARROW-4975).
+
+`StructType` gained three convenience methods to add, change and remove
+a given field (ARROW-11424).
+
+The `Datum` kind `COLLECTION` has been removed as it was entirely unused
+in the codebase (ARROW-13598).
+
+### Compute Layer
+
+A number of compute functions have been added:
+
+- functions operating on strings: "binary_reverse" (ARROW-14306),
+ "string_repeat" (ARROW-12712), "utf8_normalize" (ARROW-14205);
+- "fill_null_forward", "fill_null_backward" (ARROW-1699);
+- "ceil_temporal", "floor_temporal", "round_temporal" to adjust temporal input
+ to an integral multiple of a given unit (ARROW-14822);
+- "year_month_day" to extract the calendar components of the input
(ARROW-15032);
+- "random" to general random floating-point values between 0 and 1
(ARROW-12404);
+- "indices_nonzero" to return the indices in the input where there are
+ non-zero, non-null values (ARROW-13035).
+
+Decimal data is now supported as input of the arithmetic kernels
+(ARROW-13130).
+
+Dictionary data is now supported as input of the hash join execution node
+(ARROW-14181).
+
+Residual predicates have been implemented in the hash join node
+(ARROW-13643).
+
+The "list_parent_indices" function now always returns int64 data
+regardless of the input type (ARROW-14592).
+
+Month-day-nano interval data is now supported as input of the same functions
+as other interval types (ARROW-13989).
+
+### CSV
+
+The CSV writer got additional configuration options:
+- the string representation of null values (ARROW-14905);
+- the quoting strategy: always / never / as needed (ARROW-14905);
+- the end of line character(s) (ARROW-14907)
+
+### Dataset Layer
+
+"SkyHook", a dataset addition that offloads fragment scan operations to a
+Ceph distributed storage, was contributed (ARROW-13607).
