Appian Platform Helm Chart

• Fixed issue where `webapp.engineOverrides` field could not be set as it was incorrectly defined as an array instead of an object.
• Support setting `webapp.minHeapSize` to configure webapp's minimum heap size instead of using `customProperties`.
• Built against Appian operator v0.173.0 and Appian platform 25.1. This chart will work with other versions of the Appian operator and platform, both older and newer, but some parameters may not be valid

• Fixed issue where setting `disableResourceRequests: true` removed resource requests altogether but left limits in place, resulting in Kubernetes automatically adding resource requests back in and set to the same values as the limits. Now, setting `disableResourceRequests: true` sets resource requests to `0` to prevent this.
• Built against Appian operator v0.173.0 and Appian platform 25.1. This chart will work with other versions of the Appian operator and platform, both older and newer, but some parameters may not be valid

v1.1.0 Release Notes

• Minor increase to Search Server CPU requests for Small and Medium t-shirt sizes in-line with public docs update.
• Added `dataServer.class` field to enable independent scaling of the Data Service component without changing global t-shirt size.
• Breaking Change Aligned Data Service t-shirt sizing with latest public docs. This keeps resources relatively similar to earlier versions, but reduces RTS count for each t-shirt size. Use the new `dataServer.class` field or the `dataServer.rts.count` field to readjust if required.
• Breaking Change CPU limits are no longer set by default. This is to align with K8s best practices (where accurate CPU limits for the specific usage scenario are not already known). CPU limits can be applied by setting the new field `disableCpuLimits` to `false` (it defaults to `true`). If enabled, the t-shirt size's CPU limits are applied. This can be overridden globally by setting the new field `defaultCpuLimits` or overridden per component by setting `[component].cpuLimits`. The field `workerNodeTotalCpu` has been removed in favour of `defaultCpuLimits`. Previous chart behaviour can be achieved by setting `disableCpuLimits` to `false` and setting `defaultCpuLimits` to the previous value of `workerNodeTotalCpu`.
• Breaking Change Removed `serviceManager.cpuLimits` and `serviceManager.memoryLimits` fields. Use `serviceManager.default.cpuLimits` and `serviceManager.default.memoryLimits` instead.
• 'disableResourceRequests` now sets no `resources.requests` at all, rather than incorrectly setting them to `0`.
• Deprecated `dataSources.mysqlDriverConfigMapName`, which enabled deploying the MySQL driver via a ConfigMap and webapp init container. The supported MySQL driver is now too large to be mounted via a ConfigMap.
• Built against Appian operator v0.173.0 and Appian platform 25.1. This chart will work with other versions of the Appian operator and platform, both older and newer, but some parameters may not be valid

• Fixed an issue with the AGIC Ingress Template where an invalid `ingressClassName` was set. It now sets the annotation `kubernetes.io/ingress.class` instead, to the correct value, instead of setting `ingressClassName`.
• AGIC Ingress Template now defaults `ingressTemplate.usePrivateIp` to `false` instead of `true`.
• Built against Appian operator v0.166.0 and Appian platform 24.4. This chart will work with other versions of the Appian operator and platform, both older and newer, but some parameters may not be valid (e.g. `spec.rpa` was only introduced from v0.156.0).

• Allow storage.haSharedData to be specified when not in a high availability configuration
• No longer enforces passwordsPropertiesSecretName to be set (as this need only be provided and loaded at first environment startup)
• Support override of serviceManager.replicas in high availability configurations (from the default 3)
• Built against Appian operator v0.166.0 and Appian platform 24.4. This chart will work with other versions of the Appian operator and platform, both older and newer, but some parameters may not be valid (e.g. `spec.rpa` was only introduced from v0.156.0)

• Fixed bug preventing `ingress` from being used to completely override the templated ingress `ingressTemplate`
• Built against Appian operator v0.166.0 and Appian platform 24.4. This chart will work with other versions of the Appian operator and platform, both older and newer, but some parameters may not be valid (e.g. `spec.rpa` was only introduced from v0.156.0).

• Fixed bug preventing `webapp.dataSources` from being used to completely override the templated data sources `dataSources.primary` and `dataSources.business`
• Fixed bug where CPU and memory limits were not set for execution, analytics, groups, collaboration and process design engines when applying t-shirt sizes
• Default value of the Data Service custom property `rts.queryMemoryLimits.circuitBreaker.threshold.bytes` automatically set based on RTS count
• Added `webapp.customLoggers` to facilitate the addition of customized application logging
• Added `metricsAuthToken` to enable Appian Self-Managed Monitoring metrics API
• Added `cascadeVersionToComponentTags` for compatibility with the Appian Migration Tool
• Built-in SMTP-related custom properties are only added by the chart if `smtp.host` is provided
• `serviceManager.maxExecEngineLoadMetric` is now an integer (corrected from string)
• `dataServer.rts.count` is now an integer (corrected from string)
• `dataServer.rts.queryMemoryCircuitBreakerThresholdBytes` is now an integer (corrected from string)
• Built against Appian operator v0.166.0 and Appian platform 24.4. This chart will work with other versions of the Appian operator and platform, both older and newer, but some parameters may not be valid (e.g. `spec.rpa` was only introduced from v0.156.0).

• Added disableResourceRequests field for running on smaller, dedicated worker nodes.
• Built against Appian operator v0.161.0 and Appian platform 24.3. This chart will work with other versions of the Appian operator and platform, both older and newer, but some parameters may not be valid (e.g. spec.rpa was only introduced from v0.156.0).
• Minimum supported operator version is v0.156.0.

• Supports new Search Server API password (introduced in 24.3)
• Minor bug fixes
• Built against Appian operator v0.161.0 and Appian platform 24.3.
