Note on upgrades from pre 2.0 releases
Version 2.0 release includes a backward incompatible file format change for YSQL. Note: Prior to 2.0, YSQL was still in beta. This means that if you have an existing cluster running releases older than 2.0 with YSQL enabled, then you will not be able to upgrade to version 2.0 or higher release.
There are two ways to address the above note.
- If you don't care about preserving your existing data, then delete your cluster, and create a new
cluster with 2.0.x.x - If you want to continue using your existing data, then please save your data,
delete the cluster, create a new cluster with 2.0.x.x and then load the previously saved data.

v1.2.4 (Apr 02, 2019)
Overview of Changes
[IMPORTANT] This version includes a backward incompatible file format change for YSQL. This means that if you have an existing cluster with
YSQL schema, then you will not be able to connect to the YSQL database after upgrading to v1.2.4. There are two ways to work around this problem:
- If you don't care about preserving your existing data, then you can delete your older cluster, upgrade to v1.2.4 and create a new cluster.
- If you want to continue using your existing data, then please save your older data (in the form of SQL statements), delete the older cluster, upgrade to v1.2.4, create a new cluster and then load the previously saved data.
YSQL Changes
- Added support for primary keys. It is now possible to create a table with a primary key. #955
- Added support for temporary tables. #805
- Added support for CYCLE option in CREATE SEQUENCE statement. #993
- Enabled
SET TRANSACTION READ WRITE
statement. #1081 - Support RelationType in TableInfo to distinguish between system tables, user tables and user indexes. #906
Bug Fixes
- Fixed a crash in tserver that is observed while inserting null value into an indexed column. #945
- Fixed a bug where indexes on system catalog tables were not being updated during DDL. #1083
- Fixed detection of single row transactions on tables that have primary keys.
- Fixed MiniMaster startup race condition in test infrastructure. #1040
System Improvements
- Reduce per-connection overhead for cache preloading. #1090 #1091
- Faster release of sending buffers to reduce memory consumption when leader sends large updates to followers who are lagging behind. #1079
- Parallelize DNS resolution while filling system.peers and system.local tables #1000
- Script for post-processing test results and generating JSON-based result files.
- Improve stability of QLTransactionTest.IntentsCleanupAfterRestart. #1102
