Installation notes

Changelog

3.0.0 (2026-09-01)

Compatible with Redmine 6.1.x, 6.0.x, 5.1.x, 5.0.x.

Multi-database support¶

• Added MySQL 8.0+ and MariaDB 10.2+ support alongside PostgreSQL 11+.
• Database-specific views and stored functions are installed automatically for the configured adapter.
• SLA level, elapsed-time and diagnostic calculations produce consistent results on every supported database.

Upgrade compatibility¶

• Existing SLA types are preserved and receive deterministic positions when upgrading from an older version.
• The ordered and non-null sla_types.position migration is supported on PostgreSQL, MySQL and MariaDB.
• Existing project-level SLA permissions and secure PATCH-only cache operations are preserved.

Performance and reliability¶

• SLA level calculation now evaluates calendar days instead of scanning every minute.
• Holiday processing and elapsed-time calculations have been optimized.
• The SLA "Explain" diagnostic view is available on every supported database.

Installation requirements¶

The normal migration command remains unchanged:

bundle exec rake redmine:plugins:migrate NAME=redmine_sla RAILS_ENV=production

MySQL and MariaDB installations must provide server time-zone tables. If binary logging is enabled, log_bin_trust_function_creators must allow creation of the plugin's stored functions.

2.2.2 (2026-08-31)

Compatible with Redmine 6.1.x, 6.0.x, 5.1.x, 5.0.x.

Security and permissions¶

• SLA cache refresh, deletion and purge now require manage_sla on every affected project.
• Users with view_sla retain read-only access only to SLA caches belonging to issues they are allowed to see.
• Global SLA cache purge remains restricted to administrators.
• Project-scoped operations cannot modify caches belonging to another project.

Secure routes¶

• Cache refresh and purge operations now use PATCH instead of GET.
• State-changing requests therefore benefit from Rails' standard CSRF protection.

Upgrade reliability¶

• Includes the safe SLA type position migration introduced in 2.2.1.
• Existing SLA types are assigned deterministic positions in their previous creation order before position becomes mandatory.
• Upgrade behavior is compatible with PostgreSQL, MySQL and MariaDB.

2.2.1 (2026-08-31)

Compatible with Redmine 6.1.x, 6.0.x, 5.1.x, 5.0.x.

Upgrade fix¶

• Fixed upgrades from installations created before SLA type ordering.
• Existing SLA types receive deterministic positions in their previous creation order.
• The resulting sla_types.position column is enforced as non-null.
• The migration is portable across PostgreSQL and MySQL/MariaDB.

2.1.7 (2026-08-29)

Compatible with Redmine 6.1.x, 6.0.x, 5.1.x, 5.0.x.

SLA type reliability¶

• Dynamic SLA accessors are now resolved at runtime instead of being generated only when the application starts.
• Newly created SLA types are immediately available without restarting Redmine.
• Deleting an SLA type no longer leaves obsolete accessor methods in the application.
• The change applies consistently to issues, time entries and SLA caches.

2.1.4 (2026-08-29)

Compatible with Redmine 6.1.x, 6.0.x, 5.1.x, 5.0.x.

Performance¶

• Project-scoped SLA cache purges now use bulk deletion instead of deleting records one by one.
• SLA spent-time rows continue to be removed through the existing database cascade.
• Improves purge performance on projects containing many issues without changing functional behavior.

Full details: https://github.com/likehopper/redmine_sla/releases/tag/v2.1.4

2.2.0 (2026-08-29)

Compatible with Redmine 6.1.x, 6.0.x, 5.1.x, 5.0.x.

SLA type ordering¶

• Added drag-and-drop ordering from the dedicated /sla/types list.
• The configured order applies to issue gauges, issue and time-entry columns, the SLA Explain view and the SLA Level Terms matrix.
• Added a toggle to reveal SLA types that are not yet used by an existing level.
• Updated the SLA Level Terms matrix to use Redmine's native list presentation.

Additional improvements¶

• Fixed rounded-bar and pie-gauge rendering issues.
• SLA type accessors are now resolved dynamically.
• Improved the performance of project-scoped SLA cache purges.
• Removed routine query-building messages from error-level logs.

2.1.1 (2026-08-28)

Compatible with Redmine 6.1.x, 6.0.x, 5.1.x, 5.0.x.

SLA calculation diagnostics¶

• Added an on-demand "Explain" view for individual issue SLA calculations.
• Shows the selected SLA level and calendar, working hours and the reason why a level matched.
• Provides a day-by-day breakdown of elapsed SLA time, including weekends and holidays.
• Access is restricted to users allowed to manage SLA information for the project.

Reliability¶

• Long untracked status intervals are summarized instead of generating one diagnostic row per calendar day.
• The diagnostic view is read-only and does not modify SLA caches.
