Proposal #134202
Vote: Adopted
Reason: Builds fine and the hash matches, along with all the listed commits and the motivation makes sense.
The Argument Hex that is provided in the summary is also a match, and using the command " $ didc encode ‘()’ | xxd -r -p | sha256sum " we can also match the arg_hash from the payload.

e9b9740 fix: FI-1574: last_block_index shall be leb128 encoded
Adapted icrc3_get_tip_certificate to be compliant with the ICRC-3 specification by changing the encoding of last_block_index to leb128.
Done by adding leb128 version 0.2.5 to the list of dependecies in the toml file, setting the MAX_U64_ENCODING_BYTES constant to 10, as the maximum number of bytes required to encode a 64-bit unsigned integer (u64) in a specific encoding format in our case that being LEB128, to be used by the populate_last_block_hash_and_hash_tree function used to encode and store the last block’s index and its hash.
Using LEB128 for last_block_index ensures that small indices are represented efficiently.
The added test_u64_to_leb128 is used to verify the correctness of LEB128 encoding and decoding.

New lib leb128 introduced.
Encodes a u64 last_block_index into a compact LEB128 format, stores it in a buffer, and inserts it along with the last_block_index key into a mutable hash tree data structure.
Dfinity Copyright fix.
Unreleased is now 1.0.2 instead of 1.0.1
New type IcpXdrConversionRate and IcpXdrConversionRateResponse for query method get_icp_xdr_conversion_rate.
Changes are specifically for adding functionality to mock the ICP to XDR conversion rate.
