Fix documentation typo for Address::p2tr_tweaked

This commit fixes a single-word typo in a documentation comment. The word 'pre-tweaked' was changed to 'tweaked' to accurately describe the function's parameter. There is no code change and no security impact.

Add comment explaining push_slice()'s minimality

This commit only adds documentation comments to two Rust source files. It does not change any executable code, so it cannot introduce or fix a security vulnerability by itself. The comments explain an existing behavior of the push_slice() …

Fix ScriptBuf::push_slice() handling of 0x00

This commit fixes how the library builds Bitcoin script instructions when pushing a single zero byte (0x00) onto the stack. Previously, ScriptBuf::push_slice() emitted an invalid opcode (OP_PUSHBYTES_0, which does not exist in Bitcoin) for…

Fix push_slice() tests

This commit only updates test code. It removes an 'ignore' marker from a test and corrects the expected byte output for pushing a single zero byte onto a Bitcoin script. There is no change to production code and no security issue.

Fix script::Builder::push_slice() handling of 0x00

This commit fixes a bug in the rust-bitcoin library where calling a function to push the single byte 0x00 onto a Bitcoin script would incorrectly push an empty byte array instead. In Bitcoin scripts, pushing the number 0 (empty) and pushin…

Script encoding bug: 0x00 byte pushed as empty array instead of one-byte pushPotential for non-standard or invalid transaction scripts depending on use caseCould affect protocols relying on exact script bytes (e.g., covenants, contracts, signature hashes)

Fix script::Builder::push_verify() following a push_int()

This commit fixes a bug in the Rust Bitcoin library's script builder. When building a Bitcoin script, after pushing a number onto the stack, the builder would incorrectly remember the last opcode it had seen. This caused a later call to `p…
