Max file size - For performance and stability, files larger than 16 MB will not be opened by Brackets.
Version numbering - While previous releases of Brackets used version numbers like "0.XX", this release is numbered "1.0" and the next release (due out within a month) will be "1.1".
Deprecated APIs removed - The following APIs, which had been deprecated for some time already, have been removed:
CollectionUtils moduleStringUtils.htmlEscape()FileUtils.canonicalizeFolderPath()ProjectManager.isBinaryFile()CSSAgent.getStylesheetURLs() & CSSDocument.getStyleSheetFromBrowser() EDIT_FIND*, EDIT_ADD_NEXT_MATCH, EDIT_SKIP_CURRENT_MATCH, EDIT_REPLACE
EDIT_FIND_COMMANDS, EDIT_REPLACE_COMMANDS
Bugs have already been filed with all extensions that are believed to be using these APIs.
Themes - Themes no longer need to include a dummy 'main.js' file. Theme authors may wish to continue including this file in the short term for compatibility with Brackets 0.44, however.
Prepackaged extensions - Distributions of Brackets can now include extensions that will be auto-installed in the user extensions folder on first launch. Place extension .zip packages in a folder named auto-install-extensions next to the www folder. Users can update & uninstall these extensions individually just like regular user-installed extensions.
