+# Changelog
+
+---
+
+### Added
+- Protocol name allowlist filter: in Receiver Config, a new "Proto Filter"
+  field accepts a comma-separated list of protocol names (e.g. "Ford V2,VAG").
+  When set, the receiver ignores all decoded signals that are not in the list,
+  reducing RAM usage and increasing the chance of capturing the target protocol.
+  Leave empty to disable (default behavior, all protocols accepted).
+  Setting is persisted in last_subghz.settings under the ProtocolFilter key.
+
+### Changed
+- Protocol Filter: replaced free-text input with a dedicated protocol list
+  scene (Proto Filter in Receiver Config). All registered protocols are shown
+  as toggleable items (--- / ONLY). Selecting one or more protocols restricts
+  the receiver to only show those; leaving all as --- disables the filter.
+  The active count is shown inline in Receiver Config ("N set" or "All").
+  Filter is persisted across sessions and cleared by Reset to default.

+# Changelog
+
+All notable changes to the 24cxxprog EEPROM Programmer application will be documented in this file.
+
+## [2.0.0] - 2026-03-11
+
+### 🚀 Major Features Added
+
+#### Dynamic Memory Support for All 24Cxx Chips
+- **Full chip type support**: Added complete support for all EEPROM sizes from 24C01 (128B) to 24C512 (64KB)
+- **Dynamic buffer allocation**: Memory buffers now automatically resize based on selected chip type
+- **Configurable in Settings**: Users can now select chip type in Settings menu, and all operations adapt automatically
+
+### ✨ Enhancements
+
+#### Memory Management
+- Replaced fixed 256-byte buffers with dynamic allocation:
+  - `memory_data` - dynamically allocated based on chip size
+  - `file_data` - dynamically allocated based on chip size  
+  - `verify_buffer` - dynamically allocated based on chip size
+- Added `get_eeprom_size()` helper function returning size in bytes for each chip type
+- Added `reallocate_buffers()` function for automatic buffer reallocation on chip type change
+- Memory size tracked in `memory_size` field (32-bit for chips up to 64KB)
+
+#### Read/Write/Erase Operations
+- **Read operation**: Now reads entire EEPROM regardless of size (128B to 64KB)
+- **Write operation**: Supports writing to full address range of selected chip
+- **Erase operation**: Clears entire memory of selected chip type
+- **File operations**: Binary dumps now save/load full chip capacity
+
+#### User Interface Improvements
+- Address display format adapts to memory size:
+  - Small chips (≤256B): `0x00` format
+  - Large chips (>256B): `0000` hex format (4 digits)
+- Progress indicators updated for all memory sizes
+- Navigation (Up/Down) works across entire address range
+- File size display shows actual chip capacity
+
+#### File Naming
+- Filename generation now includes all chip types:
+  - Examples: `24C01_2026-03-11_10-30.bin`, `24C256_2026-03-11_10-30.bin`
+- Automatic timestamp-based naming for all chip variants
+
+### 🔧 Technical Changes
+
+#### Type Updates
+- Changed address/size types from `uint8_t` to `uint32_t` for large memory support:
+  - `current_address`: now `uint32_t`
+  - `read_total_bytes`: now `uint32_t`
+  - `write_total_bytes_async`: now `uint32_t`
+  - `verify_total_bytes`: now `uint32_t`
+  - `erase_current_addr`: now `uint32_t`
+  - `progress_value`: now `uint32_t`
+  - `file_size`: now `uint32_t`
+
+#### Format Specifiers
+- Updated all `printf`/`snprintf` calls to use correct format for `uint32_t`:
+  - Changed `%d` to `%lu` for unsigned long
+  - Changed `%X` to `%lX` for hex unsigned long
+
+#### Memory Safety
+- Added proper memory initialization in `reallocate_buffers()`
+- Added null pointer checks for all dynamically allocated buffers
+- Proper cleanup in `eeprom_app_free()` - all buffers freed correctly
+
+### 🐛 Bug Fixes
+- Fixed buffer overflow risk in memory operations for larger chips
+- Fixed format specifier warnings causing compilation errors
+- Fixed address boundary checking for chips larger than 256 bytes
+- Fixed progress bar calculations for larger memory sizes
+
+### 🔄 Behavioral Changes
+- Settings → Chip Type now immediately reallocates buffers
+- Current address is reset to 0 if it exceeds new chip size after type change
+- File load operation respects maximum chip capacity (won't load more than chip can hold)
+
+### 📋 Supported Chip Types
+
+Complete support matrix:
+| Chip Type | Size | Status |
+|-----------|------|--------|
+| 24C01 | 128 bytes | ✅ Full Support |
+| 24C02 | 256 bytes | ✅ Full Support |
+| 24C04 | 512 bytes | ✅ Full Support |
+| 24C08 | 1 KB | ✅ Full Support |
+| 24C16 | 2 KB | ✅ Full Support |
+| 24C32 | 4 KB | ✅ Full Support |
+| 24C64 | 8 KB | ✅ Full Support |
+| 24C128 | 16 KB | ✅ Full Support |
+| 24C256 | 32 KB | ✅ Full Support |
+| 24C512 | 64 KB | ✅ Full Support |
+
+### ⚠️ Breaking Changes
+- Binary dump files from previous versions (always 256 bytes) are incompatible with chip-specific sizes
+- Users should re-read and save new dumps after upgrading
+
+---
+
+## [1.0.0] - Previous Version
+
+### Initial Release
+- Basic read/write/erase operations
+- Fixed 256-byte buffer (24C02 only)
+- I2C address configuration
+- File load/save operations
+- Basic hex viewer

+# FlipBIP - BIP32/39/44
+
+https://github.com/xtruan/FlipBIP
+
+## Crypto toolkit for Flipper Zero
+- Using Trezor crypto libs from `core/v2.5.3` release
+
+## Background
+
+The goal of this project is to see how much crypto functionality can be brought to the Flipper Zero.
+
+### Complete
+
+- Trezor crypto C code ported into `crypto` subfolder
+  - Adapted to use Flipper hardware RNG (see `crypto/rand.c`)
+  - Imports and some C library functions modified for compatibility with FBT
+- Navigation and UI adapted from FAP Boilerplate app
+- BIP39 mnemonic generation
+  - 24, 18, or 12 words configured in settings
+- BIP39 mnemonic to BIP39 seed generation
+- Hierarchical Deterministic (HD) wallet generation from seed
+  - Generation of offline `m/44'/0'/0'/0` BTC wallet
+  - Generation of offline `m/44'/60'/0'/0` ETH wallet (coded from the $SPORK Castle of ETHDenver 2023!)
+  - Generation of offline `m/44'/3'/0'/0` DOGE wallet
+  - Generation of offline `m/44'/133'/0'/0` ZEC transparent address wallet (by @wh00hw)
+  - Similar features to: https://iancoleman.io/bip39/
+- Saving wallets to SD card
+  - Wallets are saved to SD card upon creation in `apps_data/flipbip`
+      - NOTE: `apps_data` folder must already exist on SD card!
+  - Saved wallets can be viewed between app runs
+  - Wallets are encrypted with a randomly generated key, and that key is also encrypted
+      - `.flipbip.dat` and `.flipbip.key` files are both required to be in `apps_data/flipbip`
+      - Backups of both these files `.flipbip.dat.bak` and `.flipbip.key.bak` are also maintained
+      - If you want to externally back up your wallet, I recommend copying all these files, and storing the `key` and `dat` files seperately
+  - NOTE: The wallets should be decently tough to crack off of a Flipper, however any Flipper with the app installed can load a wallet in the `apps_data/flipbip` directory if both the `key` and `dat` file are present
+- BIP39 passphrase support
+  - Configured in settings, not persisted between runs for security
+- Import your own mnemonic
+  - Lots of typing required but you can now use the wallet with an existing mnemonic you have saved
+  - Useful to convert paper backup to keys and receive addresses without relying on a laptop or phone
+- Improved receive address generation features
+  - Addresses are now generated at the same time as other pieces of wallet info
+    - This slows down initial wallet load, but makes UI much more responsive
+  - QR code files are now generated for each address and stored in the `apps_data/flipbip` directory
+    - This app is required to view the QR code files: https://github.com/bmatcuk/flipperzero-qrcode
+    - NOTE: This happens during the `View Wallet` step; you must view a wallet after generating/importing a wallet in order to ensure the address QR files are correct
+- Broke out crypto functionality into its own library using `fap_private_libs` feature
+
+### Work in Progress
+
+- More coin types
+  - Support for more custom BIP32 wallet paths
+
+### (FAR) Future
+
+- Custom wallet security
+  - User specified password
+- USB/Bluetooth wallet functionality
