+# Announcements and Developments
+
+This page tracks recent and upcoming changes to the Bittensor protocol and other major events in the Bittensor ecosystem.
+
+
+## Sub-Subnets (Major Feature Launch)
+
+**Status**: Ready for deployment on September 12, 2025
+- **What**: Sub-subnets allow subnet owners to apportion emissions across multiple sub-subnets, each running Yuma Consensus independently
+- **Key Features**:
+  - Enables up to 8 sub-subnets (IDs 0-7) within each main subnet for multi-task validation
+  - Fully backward-compatible with existing miners and validators via sub-subnet ID 0
+  - Each sub-subnet has its own weight matrix and independent emissions
+  - All validators participate in all sub-subnets with identical stake weights
+  - Miners automatically participate in ALL sub-subnets when registering for a subnet
+  - Emissions are divided evenly, but subnet owners can configure proportions.
+  - First version focuses on core functionality with additional features planned based on community feedback
+
+## Hyperparameter Rate Limiting
+**Status**: WIP
+- **What**: Prevents subnet owners from changing hyperparameters too frequently
+- **Rules**: Cannot change hyperparameters in last 10 blocks of a tempo
+- **Purpose**: Prevent exploitation where subnet owners kick off root validators to take full incentives
+- **Implementation**: Applies 7,200-block rate limit to prevent subnet owner exploitation
+
+## Child Key Fee
+
+A percentage fee will be deducted from emissions bound to validator hotkeys through a *child hotkey* relationship. This is designed to more highly incentivize validators who perform validation work, over child-key-only validators. It is being gradually rolled out to reduce surprise for the community and allow validators to adjust.
+
+**Status**: Implemented (Merged)
+- **Plan**: 
+  - Start at 1% (September 10)
+  - 30-day delay
+  - Increase by 1% per day for 17 days
+  - Final rate: 18%
+
+## Changes to the Subnet Registration/Deregistration Process
+
+**Status**: Ready for deployment on September 16, 2025
+- **Key Changes**:
+  - Subnet limit remains at 128 initially with no new registrations available immediately
+  - Immunity period reduced from 6 months to 4 months from registration block
+  - Network rate limit increased to 3 days (from 2 days) between registrations
+  - Initial lock cost set at 1,000 TAO with standard linear decay mechanism
+  - First deregistrations available approximately September 23 (one week after deployment)
+
+## Auto-Staking for Miners
+**Status**: Implemented (Merged)
+- **What**: Miners can automatically stake their mining income to a validator of their choice
+- **Implementation**: 
+  - New extrinsics `set_coldkey_auto_stake_hotkey` and `get_coldkey_auto_stake_hotkey`
+  - Set per coldkey, affects all miner hotkeys
+  - No transaction fees required
+  - Reduces sell pressure by allowing automatic delegation of mining rewards
+  - Event emission system being added to distinguish mining vs staking rewards for proper accounting
+  - Requires CLI support for configuration and management
+
+## Registration Fee Controls
+**Status**: Deployed
+- **What**: Subnet owners can configure neuron registration fees
+- **Implementation**:
+  - Subnet owners can configure neuron registration fees between 0.1 and 1 TAO
