## What's Changed * Fix: include super admin in unified permission checks by @nobodyiam in https://github.com/apolloconfig/apollo/pull/5566 ## Installation Please refer to the [Distributed Deployment Guide](https://www.apolloconfig.com/#/en/deployment/distributed-deployment-guide). ## How to upgrade from v2.5.0 to v2.5.1 There is no schema change between v2.5.0 and v2.5.1. So simply deploy v2.5.1 executables with the following sequences: 1. apollo-configservice 2. apollo-adminservice 3. apollo-portal **Full Changelog**: https://github.com/apolloconfig/apollo/compare/v2.5.0...v2.5.1

## Highlights ### Global Search for Key and Value Administrator users can now perform a global fuzzy search on the key and value of configuration items, making it easier to locate where the configuration is being used across applications, environments, clusters, and namespaces. See [Configuration queries (administrator privileges)](https://www.apolloconfig.com/#/en/portal/apollo-user-guide?id=_17-configuration-queries-administrator-privileges). ### Observer Mode for Application AccessKey Before officially enabling application keys, you can configure Application AccessKeys in observation mode to only log without intercepting configuration retrieval. ### Limitation on the Number of Namespaces and Configuration Items Users can now limit the number of namespaces and also the number of configuration items in a single namespace. See [Parameter settings for limiting the number of namespaces in the appld+cluster dimension](https://www.apolloconfig.com/#/en/portal/apollo-user-guide?id=_64-parameter-settings-for-limiting-the-number-of-namespaces-in-the-appldcluster-dimension) and [Limitation on the number of configuration items in a single namespace](https://www.apolloconfig.com/#/en/portal/apollo-user-guide?id=_65-limitation-on-the-number-of-configuration-items-in-a-single-namespace). ### Cluster-Level Permission Control Support Users can now configure editing and publishing permissions for namespaces based on cluster granularity. [Configuring permissions for different dimensions](https://www.apolloconfig.com/#/en/portal/apollo-user-guide?id=_123-configuring-permissions-for-different-dimensions). ## What's Changed * bump version to 2.4.0-SNAPSHOT by @nobodyiam in https://github.com/apolloconfig/apollo/pull/5202 * update the server config link system info page by @nobodyiam in https://github.com/apolloconfig/apollo/pull/5204 * feat: support portal restTemplate Client connection pool config by @youngzil in https://github.com/apolloconfig/apollo/pull/5200 * build(deps): bump com.mysql:mysql-connector-j from 8.0.32 to 8.2.0 by @dependabot in https://github.com/apolloconfig/apollo/pull/5217 * chore: beautify footer: github -> GitHub by @SnowOnion in https://github.com/apolloconfig/apollo/pull/5220 * 添加了管理员全局搜索Value值的功能 by @xiaoxianhjy in https://github.com/apolloconfig/apollo/pull/5182 * fix：Fixed link namespace published items show missing some items by @youngzil in https://github.com/apolloconfig/apollo/pull/5240 * solve the problem of duplicate comments and blank lines by @youngzil in https://github.com/apolloconfig/apollo/pull/5232 * feat: add determine appid+cluster namespace num limit logic by @youngzil in https://github.com/apolloconfig/apollo/pull/5228 * feat: add observe status access-key for pre-check and logging only (#5216) by @larry4xie in https://github.com/apolloconfig/apollo/pull/5236 * feat: add determine single namespace item num limit logic by @youngzil in https://github.com/apolloconfig/apollo/pull/5227 * feat: ConfigService cache record stats by @youngzil in https://github.com/apolloconfig/apollo/pull/5247 * fix：RefreshAdminServerAddressTask supports dynamic configuration of time interval by @youngzil in https://github.com/apolloconfig/apollo/pull/5248 * fix：Optimize the default log path configuration by @youngzil in https://github.com/apolloconfig/apollo/pull/5251 * refactor: Configuration files uniformly use Kebab style by @youngzil in https://github.com/apolloconfig/apollo/pull/5262 * [Docs]OSPP Support Kubernetes ConfigMap for Apollo java, golang client by @dyx1234 in https://github.com/apolloconfig/apollo/pull/5233 * feat: openapi query namespace support not fill item by @youngzil in https://github.com/apolloconfig/apollo/pull/5249 * refactor(sql): align database ClusterName and NamespaceName fields lengths by @youngzil in https://github.com/apolloconfig/apollo/pull/5263 * feat(biz): Added the value length limit function for AppId-level configuration items by @youngzil in https://github.com/apolloconfig/apollo/pull/5264 * chore: typo fix by @arrow1991 in https://github.com/apolloconfig/apollo/pull/5272 * fix: keep clusters order in envclusters openapi by @uucloud in https://github.com/apolloconfig/apollo/pull/5277 * Bump com.thoughtworks.xstream:xstream from 1.4.20 to 1.4.21 to fix CVE-2024-47072 by @nisiyong in https://github.com/apolloconfig/apollo/pull/5280 * Create quick-start-btpanel.md by @bestlaw66 in https://github.com/apolloconfig/apollo/pull/5274 * feat: highlight diffs for properties by @WTIFS in https://github.com/apolloconfig/apollo/pull/5282 * Feature/openapi rate limit function by @youngzil in https://github.com/apolloconfig/apollo/pull/5267 * feat: add JSON format button in apollo-portal by @WTIFS in https://github.com/apolloconfig/apollo/pull/5287 * add missing url patterns for AdminServiceAuthenticationFilter by @nobodyiam in https://github.com/apolloconfig/apollo/pull/5291 * upgrade cache action version by @nobodyiam in https://github.com/apolloconfig/apollo/pull/5297 * support java.time.Instant serialization with gson by @nobodyiam in https://github.com/apolloconfig/apollo/pull/5298 * Code style-Optimize some code structures to improve readability by @youngzil in https://github.com/apolloconfig/apollo/pull/5293 * Add usage instructions for multiple appid in the Apollo client by @TerryLam2010 in https://github.com/apolloconfig/apollo/pull/5295 * typo: portal access admin service by @liubingyan127 in https://github.com/apolloconfig/apollo/pull/5305 * [Docs]OSPP-Add more observability in apollo config client by @Rawven in https://github.com/apolloconfig/apollo/pull/5229 * docs(charts): 更新 Helm chart 包和索引 by @lambda-hj in https://github.com/apolloconfig/apollo/pull/5310 * Feat(Auth): Authorization by Env Cluster by @BlackBear2003 in https://github.com/apolloconfig/apollo/pull/5302 * optimize: pre check dataChangeCreatedBy in updateItem by @k8scat in https://github.com/apolloconfig/apollo/pull/5316 * fix apollo-on-kubernetes link by @nobodyiam in https://github.com/apolloconfig/apollo/pull/5317 * feat: Email notification when releasing by OpenAPI by @BlackBear2003 in https://github.com/apolloconfig/apollo/pull/5324 ## Installation Please refer to the [Distributed Deployment Guide](https://www.apolloconfig.com/#/en/deployment/distributed-deployment-guide). ## How to upgrade from v2.3.0 to v2.4.0 1.

## Highlights ### Support for H2 Database Apollo now supports the H2 database, ideal for rapid deployment scenarios. For further details, refer to PR #4851. ### Release Histories Retention Users can now adjust how many release histories to keep for each namespace, reducing the risk of too many histories overloading the database. For more info, please see the [documentation](https://www.apolloconfig.com/#/en/deployment/distributed-deployment-guide?id=_3212-apollorelease-historyretentionsize-number-of-retained-configurations-release-history). ### Log Directory Relocated to /opt/logs The log files for Apollo ConfigService, AdminService, and Portal are now all in `/opt/logs`, instead of in separate folders like `/opt/logs/10003171`, `/opt/logs/10003172`, and `/opt/logs/10003173`. ### Create Applications with OpenAPI Open API consumer tokens now include a flag indicating permission to create applications. When set to 'yes', users are enabled to create applications using the consumer token through the Open API.  ### Grayscale Functionality for Non-Properties Namespaces Grayscale release is now enabled for non-properties namespaces, such as YAML and JSON. ### Audit Log for Administrators Administrators now have access to detailed audit logs via the `Audit Log` feature located in the Admin Tools section.   ## What's Changed * fix: PULL_REQUEST_TEMPLATE.md old url by @weiyichao in https://github.com/apolloconfig/apollo/pull/4726 * bump version to 2.2.0-SNAPSHOT by @nobodyiam in

## Highlights ### Admin Tools Enhancement **User management enhancement** The user management page now has a list view of all users and administrators can easily find a specific user to edit.  **System configuration enhancement** The system configuration page now has a list view of all configuration items of PortalDB as well as ConfigDB. Administrators can easily find a specific configuration item to edit.   **Open platform authorization management enhancement** The open platform authorization management page now has a list view of third-party apps and administrators can easily find a specific app to grant permission.  ### Basic Types for Item Users can now config the types of the item and apollo would do a basic type check based on the type. The types available now are String(default), Number, Boolean, and JSON.  ### Non-properties Namespaces Comparison Feature The comparison feature for non-properties namespaces is now available.  ### Support Database as the Service Registry for apollo-configservice and apollo-adminservice Apollo now supports the use of database as the service registry, without relying on a third-party service registry such as eureka. See [database-discovery](https://www.apolloconfig.com/#/en/deployment/distributed-deployment-guide?id=_2235-database-discovery) for more information. ## What's Changed ### Features * Optimize

refer to the [Distributed Deployment Guide](https://www.apolloconfig.com/#/en/deployment/distributed-deployment-guide). ## How to upgrade from v2.0.1 to v2.1.0 * Apply [apolloconfigdb-v200-v210.sql](https://github.com/ctripcorp/apollo/blob/master/scripts/sql/delta/v200-v210/apolloconfigdb-v200-v210.sql) to ApolloConfigDB * Deploy v2.1.0 executables with the following sequences: * apollo-configservice * apollo-adminservice * apollo-portal * Execute the following SQL to clear the spring sessions as spring security sessions are not compatible between versions, see https://github.com/spring-projects/spring-security/issues/9204 ```sql use ApolloPortalDB; delete from `SPRING_SESSION_ATTRIBUTES`; delete from `SPRING_SESSION`; ``` ## New Contributors *
