# Change Log ## 4.0 > Released 10/21/2017 * Major breaking changes arriving in v4. ### New Features * Ability to read data from a specific offset. ex: readInt8(5) * Ability to write over data when an offset is given (see breaking changes) ex: writeInt8(5, 0); * Ability to set internal read and write offsets. ### Breaking Changes * Old constructor patterns have been completely removed. It's now required to use the SmartBuffer.fromXXX() factory constructors. Read more on the v4 docs. * rewind(), skip(), moveTo() have been removed. * Internal private properties are now prefixed with underscores (_). * **All** writeXXX() methods that are given an offset will now **overwrite data** instead of insert * insertXXX() methods have been added for when you want to insert data at a specific offset (this replaces the old behavior of writeXXX() when an offset was provided) ### Other Changes * Standardizd error messaging * Standardized offset/length bounds and sanity checking * General overall cleanup of code. ## 3.0.3 > Released 02/19/2017 * Adds missing type definitions for some internal functions. ## 3.0.2 > Released 02/17/2017 ### Bug Fixes * Fixes a bug where using readString with a length of zero resulted in reading the remaining data instead of returning an empty string. (Fixed by Seldszar) ## 3.0.1 > Released 02/15/2017 ### Bug Fixes * Fixes a bug leftover from the TypeScript refactor where .readIntXXX() resulted in .readUIntXXX() being called by mistake. ## 3.0 > Released 02/12/2017 ### Bug Fixes * readUIntXXXX() methods will now throw an exception if they attempt to read beyond the bounds of the valid buffer data available. * **Note** This is technically a breaking change, so version is bumped to 3.x. ## 2.0 > Relased 01/30/2017 ### New Features: * Entire package re-written in TypeScript (2.1) * Backwards compatibility is preserved for now * New factory methods for creating SmartBuffer instances * SmartBuffer.fromSize() * SmartBuffer.fromBuffer() * SmartBuffer.fromOptions() * New SmartBufferOptions constructor options * Added additional tests ### Bug Fixes: * Fixes a bug where reading null terminated strings may result in an exception.
