Feature announcements, behind-the-scenes looks at how AlgoBlazer is built, and what is coming next.
Mock interviews launch with a shared editor and Run, private interviewer notes, a stopwatch, a drawing canvas and a full replay of the session; saved lists get the catalog's search and filters; study groups lean toward problems nobody in the room has solved; and a handful of presence and chat fixes.
Emoji reactions on every chat surface, a calendar of past daily challenges, rank insignia next to usernames, every language moved to the compiler, runtime and library set LeetCode runs, and a page documenting those runtimes.
Every solve earns XP now, across twelve ranks from Lil' Bit to Algo Blazer, and your history is already counted. The profile page is rebuilt as a dashboard, Learn category pages open with a short primer, and BFS and DFS each split into a tree half and a graph half.
Python solutions can use SortedList, SortedDict and SortedSet without an import line. The "How to use this section" guide on the Learn page is now seven short lines that stay on screen.
Python solutions start with the standard library already imported. Ctrl/Cmd+Z had stopped undoing your code in three separate ways, and all three are fixed. Also — example blocks wrap, the study-group sidebar survives a crowd, and the Learn map no longer goes blank after a database blip.
Java 25, Node 24 and Rust 1.98 replace runtimes from 2019, tree problems diagram their examples, the Learn section explains itself, and all 291 problem statements were rewritten to one voice.
Swift is the eighth language on every problem, a notification bell lands in the header, global chat keeps a 30-day backlog you can page through, and the emote set grows to around ninety.
Global chat moves onto the dashboard with unread badges, problem reports get a reply thread, Python and JavaScript get more memory, and study group code survives the end of the session.
Every problem gets an Activity feed with reactions and comments, the dashboard shows where the people you follow are right now, and the editor learns Vim, Emacs, and run/submit hotkeys.
A site-wide chat channel with emotes, live Twitch streams on the dashboard, real tree structures in tree problems, and a new beyond-interview tier in Learn.
C# joins the language list, study groups get problem selection and session history, submissions get a proper viewer, and problems now say which companies asked them.
The /practice section moves to /learn, C++ submissions compile as C++20, the editor gains word wrap and a safer Reset, and another dozen problems arrive.
Practice rooms get a collaborative drawing canvas, the dashboard shows who's solving right now, and 23 new problems land across the catalog.
Every problem now has a Discussions tab and spoiler-safe topic tags, your full submission history is browsable, and Learn gets next/prev navigation.
Solve problems together in real time, ask the AI why your code isn't working, and climb Learn ladders rebuilt from the ground up.
