© 2026 AnnounceHQ. All rights reserved.
New July 9, 2022
GA release v1.1.5 Changes since 1.1.4 : https://github.com/github/gh-ost/compare/v1.1.4...v1.1.5
gh-ost v1.1.5 is based on v1.1.4, plus commits cherry-picked from master branch.
Notable:
Cancel any row count queries before attempting to cut over, #846, thanks @ajm188
Add context/timeout to HTTP throttle check, #1131, thanks @timvaillancourt
Throttler will now throttle migration on HTTP timeouts to throttler source. This may cause a change in behaviour in rare cases (more throttling)
New command line flags:
--throttle-http-interval-millis - Number of milliseconds to wait between HTTP throttle checks (default 100) --throttle-http-timeout-millis - Number of milliseconds to use as an HTTP throttle check timeout (default 1000)
HTTP throttler calls now use gh-ost/VERSION-HERE as a User-Agent header
Use switch statements for readability, simplify .NewGoMySQLReader(), #1135, thanks @timvaillancourt
Ensure mysql rows responses are closed, #1132, thanks @timvaillancourt
compound pk tests, #387, thanks @shlomi-noach
Fix integer divide by zero panic in migrator, #1140, thanks @timvaillancourt for the PR and @ethankhall for reporting
fix: lost data in mysql two-phase commit, #1141, thanks @shaohk
Add golangci-lint CI action, fix gosimple, govet + unused lint errors, #1127, thanks @timvaillancourt
Check RowsAffected when applying DML events to get more accurate statistics, #844, thanks @ajm188
--replication-lag-query command line flag will be deprecated in gh-ost release 1.1.7 This release is not based on the master branch as it contains a known issue that is currently being investigated - please note that the master branch of gh-ost is not considered stable; only releases are considered production-ready.
Thank you to all contributors!
Updated 20th July 2022: RPM and deb packages have been updated to correctly include x86-64 binaries instead of arm64 binaries (thanks @Cartman75 for the issue report!)
